Book Review: ‘F.P. Journe Invenit et Fecit’ By Jean-Pierre Grosz Quill & Pad
F.P. Journe Invenit et Fecit’ Dec 10, 2019

Book Review: ‘F.P. Journe Invenit et Fecit’ By Jean-Pierre Grosz

‘F.P. Journe Invenit et Fecit’ by Jean-Pierre Grosz narrates the story of François-Paul Journe, one of the most successful independent watchmakers of our time. This book outlines both Journe’s incredible and – dare I say – courageous career and delves into his personal life, which wasn’t always rosy and light. A very atypical career that deserves the attention it receives with this book, Elizabeth finds it is a must-read.

Cambodia’s First Watchmaking School Opens in Phnom Penh

One of Asia’s quickest growing economies, Cambodia remains a relatively small market for mechanical watches, but now boasts its own watchmaking school – led by a pair of former WOSTEP instructors – which will begin operations in mid 2020. Supported by a local real estate conglomerate, the Prince Horology Vocational Training Center will offer a full-time, two-year course in watchmaking. Totalling some 3,400 hours of training, the watchmaking course will be comprehensive and modelled on the education offered by Swiss watchmaking schools. Designed by a team that includes a former director of WOSTEP, Switzerland’s leading watchmaking school, the course includes watchmaking history and culture, toolmaking and maintenance, repair and servicing of both mechanical and quartz watches, as well as some parts production. Filled with brand new equipment, the school is ready for its first students Located in the Chrouy Changvar district of central Phnom Penh, the country’s capital, the Prince Horology Vocational Training Center recently opened its premises, which are fully equipped with brand new benches and tools, giving students the opportunity to learn both watch repair as well as movement part production and finishing. The school’s leadership team includes Jessica Thakur, formerly an instructor at Richemont’s American watchmaking school in Texas and then at WOSTEP, as well as Maarten Pieters, who was the director of WOSTEP from 2002 to 2018. Prior to that, Mr Pieters ...

Casio Introduces the G-Shock “Full Titanium” Camouflage

Just a few months after the G-Shock 5000-series in titanium was unveiled, Casio has announced the G-Shock GMW-B5000TCM-1, which is essentially the same but with an unusual, laser-engraved camouflage pattern on the case and bracelet. The pattern is achieved by varying the size of the pixels that make up the camouflage motif; three different pixel sizes are engraved to create shading of the camouflage. The rest of the watch is identical to the standard titanium model, which means a sapphire crystal, black screen and gold accents. The case is in lightweight titanium case and bracelet – coated in black diamond-like carbon (DLC) – weighing just 110g in total. (Editor’s note: I handled one just last week and it’s a cool-looking watch that light on the wrist, but the price is pretty steep for what it is, though it’s probably worth the premium just for the cool factor.) Also announced at the same time is the G-Shock MTG-B1000DCM-1A, which has the same engraved camouflage pattern, except on the steel case and bracelet that have a black ion-plated (IP) coating.

Business News: LVMH Buys Tiffany & Co. for US$16.2 Billion

After several weeks of negotiations, LVMH has sealed the deal to buy Tiffany & Co. in a US$16.2 billion, all-cash deal. Despite several years of listless growth and a declining share price – though its current management was in a midst of engineering a turnaround – Tiffany & Co. is the biggest acquisition ever in the luxury goods industry. The French luxury conglomerate, which owns Louis Vuitton and Christian Dior, is paying US$135 a share, about 35% above the last traded price before news of the takeover broke. With the acquisition of the storied American jeweller, LVMH strengthens its presence in the “hard” luxury business of jewellery and watches, a segment traditionally dominated by its Swiss rival Richemont, the owner of Cartier, Van Cleef & Arpels, and most recently, Buccellati. The addition of Tiffany’s to its 75-strong stable of brands, which includes watchmakers like Hublot and TAG Heuer, will also help LVMH grow its presence in China and the United States, where the jeweller’s baubles are popular. And the deal also means Tiffany’s well regarded chief executive, Alessandro Bogliolo, returns to LVMH, where he was once the chief operating officer at Bulgari.

Omega Introduces the James Bond Limited Edition Set

Omega is slowly counting down to the latest James Bond film, No Time to Die, which is scheduled for April 2020, with a trickle of 007-themed watches. Just two months ago it debuted a Seamaster Diver 300M to mark half a century of On Her Majesty’s Secret Service (OHMSS),  and now it’s the release of a box set of two watches in steel and gold respectively, presented in a suitcase by British luggage maker Globe-Trotter. Limited to 257, the James Bond Limited Edition Set is made up of a pair of Seamaster dive watches almost identical to the earlier OHMSS edition but without the date. Both are essentially variants of the 42mm Seamaster Diver 300M but tweaked to incorporate several references to 007. The stainless-steel model features a black ceramic bezel insert with a white enamel scale, while the yellow gold version has a scale of Ceragold, which is ceramic with gold filling for the markings. Both have black ceramic dials engraved with the gun barrel motif taken from the title sequence of James Bond films. The hands and indices of both models are yellow gold, with the 12 o’clock marker inspired by the fictional Bond family coat of arms. A subtle detail is the “50” embedded within the luminous marker at ten o’clock, visible only in the dark, a nod to the 50th anniversary of OHMSS. And there’s also the tiny “007” that takes the place of the marker on the minute track. A commemorative plate bearing the set serial number is screwed into the side of the case, ...

Panerai Introduces the Radiomir California PAM 931 & Radiomir 8 Days PAM 992

Panerai’s new launches this year have so far been inclined towards civilian sports – including the Luna Rossa trio and Mike Horn edition – which is a key part of chief executive Jean-Marc Pontroué’s strategy that also emphasises “experiences”. But with its two new launches – the Radiomir California 47mm (PAM 931) and Radiomir 8 Days 45mm (PAM 992) – the brand returns to the old school Marina Militare style – both have a familiar look that’s heavily inspired by wristwatches Panerai made for frogmen of the Italian navy in the 1930s and 1940s. Radiomir California 47mm PAM00931 Notably, both watches have steel cases with an “aged patina effect”, essentially a surface coating that reproduces the look of the vintage originals. The Radiomir California 47mm (PAM00931) revisits a design that Panerai has reproduced several times in the past – modelled on the ref. 3646 of the 1930s – but now with a “tropical” dial in graduated brown that mimics the look of aged dials on vintage Radiomir watches. It has Roman numerals on the upper half and Arabic numbers on the bottom, a design originally meant to aid legibility by clearly distinguishing the upper and lower halves of the dial. The crystal is domed PlexiGlas, while the movement is the extra-large, hand-wound P.3000 with a three-day power reserve. The second model is slightly more interesting, since the design is more novel (in other words having not been done before, at least in the exact same con...

Zenith Defy Classic Blue Ceramic Review WatchAdvice
Zenith Defy Classic Blue Ceramic Nov 14, 2019

Zenith Defy Classic Blue Ceramic Review

The future of watchmaking for Zenith can be narrowed down to one word: Defy. The Defy collection started with the release of the Defy El Primero 21 back in 2017, which was the quite amazing hundredth-of-a-second chronograph. This was followed by the first-generation Defy Lab (known now as Defy Inventor), which Zenith states is the world’s most accurate watch with its new ground-breaking monocrystalline silicon oscillator. Luckily enough, we had a chance to review the Zenith Defy Inventor as well, which you can check out here. Zenith has added a mini collection of three ceramic models to the Defy Classic range. The models in the Defy Classic Collection has a three-hand plus date feature and comes in three colour variations: White ceramic, Black ceramic and Blue ceramic. The piece we have on our hands today is the elegant Defy Classic Blue Ceramic. Having a colour outside of the typical white and black in a ceramic, which is the norm, definitely brings something different to the table. Although the colour blue may have its limitations with what it can be worn with, compared to all black and white ceramic watches. Despite this limitation, the blue ceramic certainly is an eye-catcher when on the wrist. Like the other two models in the Zenith Defy Classic Ceramic range, the blue ceramic comes with its own matching blue rubber strap.  Sometimes having too much of the same colour throughout the watch can be too “in your face” as well. The blue used by Zenith for this cera...

Highlights: Phillips ‘Double Signed’ Geneva Auction Part II SJX Watches

Highlights: Phillips ‘Double Signed’ Geneva Auction Part II

Here’s part II of highlights at Phillips’ Double Signed auction – you’ll find the first part here – including a lovely Audemars Piguet “Gobbi” chronograph with a green gold dial, as well as a gorgeous Patek Philippe Ref. 1463 “pink on pink” that’s more affordable than usual, for a reason. Lot 35 – Patek Philippe ref. 2499 in pink gold “Trucchi” The most valuable lot in the sale, with an estimate over 1.2m francs, is the Patek Philippe ref. 2499 third series in pink gold. It’s one of only six pink gold third series watches known; in fact, the total number of ref. 2499s in pink gold across all four series totals just 23. And this is the only one with the “Trucchi” signature on the dial, having been sold by the retailer in Naples that’s still in operation today. According to Phillips, it was sold by Trucchi to an Italian-American doctor in 1972, who then sold it to the consignor who sold the watch at auction in 1999 at Antiquorum in Geneva. It sold for almost 700,000 francs then, making it one of the most expensive watches in the world at the time. The watch is in exemplary condition, albeit with one quirk: the crystal is sapphire instead of PlexiGlas as is standard for the third series. Found only on fourth series ref. 2499s, the sapphire crystal and accompanying bezel was presumable installed by Patek Philippe in the 1980s according to Phillips, since the watch already had a sapphire crystal when it was sold in 1999.

Interview: Wilhelm Schmid of A. Lange & Söhne on the Odysseus

Shortly before A. Lange & Söhne launched the Odysseus Datomatic, its chief executive Wilhelm Schmid was in Singapore to officially reopen its revamped boutique. But perhaps more importantly, he was available to discuss the Odysseus, which I did. In the articulate and frank manner that is his style, Mr Schmid outlined the rationale behind the Odysseus, how it came to be, and drops a few hints as to where it’s going. Read what he had to say below. The interview was edited for clarity and length. You have established Lange’s reputation for watches of high quality; quality that no one disputes. Now you’re taking the next step into a different segment. What’s the rationale behind this? We have not changed our fine watchmaking, [but we had to decide:] do we answer the question that has been raised by many customers over many years? If you do something like that, you have to be unique, you have to be different, and it has to be of some interest for the customer. We rather not provide an answer than provide the wrong answer. So it took us a long time to find the face and find the design. And then after we created the idea, [we had to create] something which will be recognisable within this sort of design, [with] the push buttons, the day-date complications. Then, how can we use that to create a family? It’s always easy to come up with one watch. It’s often more difficult if you want to have a recognisable face that can have different iterations and complications lat...

Hands-On: De Bethune DB28 Yellow Tones SJX Watches
De Bethune DB28 Yellow Tones Even Oct 29, 2019

Hands-On: De Bethune DB28 Yellow Tones

Even amongst avant-garde watchmakers, De Bethune stands out for its substance – aesthetic and material innovation matched by technical ingenuity. At its core, the brand has reimagined the most fundamental aspects of mechanical timekeeping, from the barrel to the hairspring, while pushing the boundaries of traditional complications, be it the moon phase, tourbillon or chronograph. But arguably its most distinctive innovation is an aesthetic one, which has come to define the brand no less – heat-blued titanium. The brand has used the alloy for more than 15 years across various parts of the watch, even making almost a whole watch out of it. But now De Bethune has a twist on the theme, resulting in the DB28 Yellow Tones in brilliant golden titanium. Fiery yellow Though the colour of the new DB28 is striking, it is by no means loud, as the amber shade of yellow isn’t the same as yellow gold and doesn’t pass off as such. In fact, it looks more like fresh brass than gold. The colour was achieved through thermal oxidisation of the surface, essentially the same process as that used for blued titanium (and also the same for blued steel). The yellow surface, just like the blue, is the result of an oxide that forms on the surface of titanium when it is heated to a certain temperature. But amber yellow tone in this case was created by heating it at a lower temperature than used for blued titanium. Titanium undergoes different stages of oxidation when heated, and yellow is o...

Business News: LVMH Offers to Buy Tiffany & Co. SJX Watches

Business News: LVMH Offers to Buy Tiffany & Co.

Luxury giant LVMH has made an offer to buy Tiffany & Co., America’s leading luxury jeweller (and the biggest retailer of Patek Philippe watches in the country), according to the Bloomberg. The French group made an all-cash offer of US$120 a share, a premium of about 22% over Tiffany’s last done share price and valuing the company at about US$14.4 billion. That would make Tiffany’s the biggest acquisition ever for LVMH, which has seen its shares hit record highs recently, bringing its value to over US$210 billion. Despite being the world’s largest luxury group – its brands include Louis Vuitton, Bulgari, Rimowa, Hublot and DFS – LVMH is relatively weak in high-end jewellery, especially compared to Swiss rival Richemont, which owns Cartier, Van Cleef & Arpels, and Piaget, and only just picked up Buccellati. Buying Tiffany would give LVMH a bigger presence in jewellery, as well as greater exposure to the United States, which is the jeweller’s biggest market, account for around a third of sales. LVMH only just opened a bag factory in Texas, the Louis Vuitton Rochambeau Ranch, in an event attended by Donald Trump and LVMH chief executive and controlling shareholder Bernard Arnault, who’s also the third-richest man in the world. Best known for its diamond engagement rings and blue boxes, Tiffany suffered from a weak spell in recent years, with its former chief executive Frederic Cumenal, an LVMH alumni, lasting barely two years. After he departed in 2017, to be...

Panerai Introduces the Luminor Luna Rossa Collection

Back in January, Panerai unveiled the Luna Rossa Challenger Submersible Carbotech, which kicked off the watchmaker’s official sponsorship of Luna Rossa, the challenger of the 36th America’s Cup that takes place in 2021. And now the brand has introduced three Luminor watches – the Luna Rossa Regatta (PAM01038), the Luna Rossa Chrono Flyback (PAM01037), and the Luna Rossa GMT (PAM01036) – dedicated to the sailing syndicate, which has fellow Italian brands Prada and Pirelli as its main sponsors. Only just unveiled at the Salón Internacional Alta Relojería (SIAR) watch fair in Mexico City, the three watches are characterised by high tech materials that also used in Luna Rossa. The watches share the same monochromatic palette, with a distinctive “sandwich dial” made up of a lower dial plate with luminous paint for the numerals that’s capped with an upper dial plate covered in sailcloth from Luna Rossa. Though each use different case materials, they all share the same titanium case back engraved with the Luna Rossa and the team logo. Luminor Luna Rossa Regatta (PAM01038) A dedicated yachting chronograph, the Luminor Luna Rossa Regatta is the flagship model of the range. It has a 47mm case in Carbotech, a proprietary carbon fibre-reinforced polymer, making it massive but lightweight. First introduced in 2015, the material is produced by layering sheets of carbon with a polymer resin in between to create a light and strong composite with a woodgrain appearance. ...

Rolex Unicorns Part II – Oct 13, 2019

Rolex Unicorns Part II – Ref. 8171 Triple Calendar “Padellone” in Steel

If I had a million dollars, or maybe two, to buy a Rolex, I could perhaps buy a ref. 4113 split-seconds, which is very large, very flat – a bit too large and flat for me – and exceptionally rare. Or I could buy a ref. 8171 triple calendar in steel, one in almost “new old stock” condition, as Phillips has in its upcoming Geneva auction. The ref. 8171 in question reminds me of the 369-year old Jehan Cremsdorff pocket watch Sotheby’s sold in the summer – it’s hard to believe something that old, admittedly not quite four centuries, can be so well preserved. The “Padellone” is incredibly – incredibly – clean and crisp. Up close, the ref. 8171 speaks for itself. The dial looks like the watch left the factory recently. It is clean, neat and the date track is in pure, vivid blue. Similarly, the hands are free of marks, meaning they were seldom, or never, removed from the dial. The condition of the dial is all the more unusual due to the fact that the ref. 8171 is not an Oyster. Instead, it has a snap-on back, instead of the water-resistant, screw-on back found on the Oyster watch case. Over time, snap backs tend to lose their water-resistance as a consequence of corrosion or deformation from repeated opening, which is why most ref. 8171s have dials that show obvious ageing. An example of a ref. 8171 with a dial showing ageing, this one offered at Christie’s Hong Kong in 2017 The steel case is similarly well preserved. Fortunately, steel is nota...
