Here We Glow: The Speake-Marin Dual Time Lime

Coming from an incredibly specific corner of the independent luxury market, Speake-Marin are probably not a brand you come across very often either online or in the metal. Originally creating bespoke watches for clients one at a time, the brand established a unique style that guarantees curiosity when spotted on the wrist, their cult following … ContinuedThe post Here We Glow: The Speake-Marin Dual Time Lime appeared first on Time+Tide Watches.

Rexhep Rexhepi Debuts the Chronomètre Contemporain II SJX Watches

Rexhep Rexhepi Debuts the Chronomètre Contemporain II

Having already been revealed as a one-off for Only Watch 2021 – that sold for a record CHF800,000 – the Rexhep Rexhepi Chronomètre Contemporain II (RRCCII) has now made it into regular production, albeit as a limited edition. The standard RRCC II is identical to the example made for Only Watch, save for the dial. Inside is the RRCC02, an all-new calibre with twin going trains as well as an independently-driven deadbeat seconds with hacking and zero-reset functions. And the dial is a two-piece affair in fired enamel – black for the platinum model and translucent white for the gold. Initial thoughts With the first edition having become the signature watch of Akrivia, it’s no surprise that the RRCCII continues down the same road in terms of design. But the RRCCII is not just a facelift; it is an entirely new watch. The movement is a new construction in both layout and complications, while none of the case components are interchangeable between the two generations. At the same time, the movement decoration – the most easily observed quality of Akrivia watches – has been refined. It is impressively executed and even exaggerated in some respects. The bevelling on the bridges, for example, is remarkably broad for a relatively thin watch. The degree of technical advancement from the first to second editions is impressive and demonstrates Mr Rexhepi’s pursuit of progress despite his brand’s tremendous success. The RRCC02 is instantly recognisable as a new calibre...

Panerai Introduces the Ultra-Luxe Luminor Marina Platinumtech PAM 1116 SJX Watches

Panerai Introduces the Ultra-Luxe Luminor Marina Platinumtech PAM 1116

After not having had a platinum model in the catalogue for some time, Panerai is returning to the lustrous and heavy metal with the Platinumtech Luminor Marina PAM01116. But the case of the PAM 1116 is not conventional, PT950 platinum alloy used in most wristwatches, instead it is an extra-hard alloy with better wear resistance. And like many of Panerai’s recent top-of-the-line models, the Platinumtech Luminor boasts a 70-year warranty – which is double emphasised by an oversized emblem on the sapphire back. Initial thoughts Panerai’s recent launches have leaned towards lightweight alloys or composites, which makes the Platinumtech Luminor unusual. The brand has made platinum watches in the distant past – in both Radiomir and Luminor format – and they were always impressively heavy watches with a heft that matched their price tag. The new Platinumtech Luminor is doubtlessly just as impressive in tangible feel, and it is also helped by the olive-green dial that’s unconventional but attractive. The watch is accompanied by an impressive 70-year warranty, but it feels more like a gimmick than something of practical value. Aside from the decades that stretch beyond the lifetime of most living buyers, the movement inside the watch is a straightforward calibre that doesn’t need a 70-year warranty (which is probably why it’s viable for Panerai to offer one in the first place). The Platinumtech Luminor  is expensive for a contemporary Panerai, though not all tha...

Our Predictions In The Chronometry Category Of The 2020 Grand Prix d’Horlogerie de Genève (GPHG): Our Panel Is United, But Not Unanimous

In the GPHG Chronometry category, we find mechanical watches that contain at least one tourbillon, and/or a special escapement, and/or another development improving precision timekeeping. What we don't find, though, is much hard data regarding precision like timing test results or in most cases even a second hand. Precision watches without a second hand? Despite that, our panel predicts a clear winner.

Atelier de Chronométrie Introduces the AdC #8 Split-Seconds Chronograph SJX Watches

Atelier de Chronométrie Introduces the AdC #8 Split-Seconds Chronograph

Barcelona-based Atelier de Chronométrie made a name for itself with its beautifully crafted watches that capture the grace of 1940s timepieces. But all of its work so far has centred on time-only watches, all powered by heavily decorated vintage Omega movements. But now the AdC #8 Split-Seconds Chronograph takes things to a whole new level. Retaining the elegant feel of the brand’s earlier creations, the AdC #8 is powered by a reworked movement that started out as a Venus 185 but completely reworked by Atelier de Chronométrie, with a substantial number of parts made from scratch. Commissioned by an American collector, the AdC #8 is largely hand made, with everything hand finished to a superlative, artisanal standard, which is why it took took two years to complete. Initial thoughts I first found out about this watch late last year, and it sounded promising given Atelier de Chronométrie’s track record in design and movement finishing. Though I am going by photos, the finished product definitely lives up to expectations, and then some. Everything about it is just done extremely well, and while it costs a lot of money, the AdC #8 is compellingly and reasonably priced as such things go. Having closely examined Atelier de Chronométrie’s earlier watches, the AdC #8 will undoubtedly have the same feel – visually similar to a vintage watch but much more solid in the hand thanks to a more robust, modern case. A little under 40 mm in diameter, the AdC #8 has the proporti...

F.P. Journe Introduces the New Chronomètre à Résonance SJX Watches

F.P. Journe Introduces the New Chronomètre à Résonance

Since its launch in 2000, the Chronomètre à Résonance has perhaps become the quintessential F.P. Journe wristwatch. Still the only wristwatch to rely on the principle of resonance – omitting any mechanical means of transmission – the Résonance has been revamped and improved for its 20th anniversary. While the Résonance was powered by essentially the same calibre (the cal. 1499 in several generations) for its first two decades, the new Chronomètre à Résonance is equipped with the brand-new cal. 1520. Several features set the new movement apart from its predecessor, most notably the use of a single barrel and a remontoir d’egalite constant force mechanism in each going train. Initial thoughts Having learnt a little about the new Résonance from hints dropped by Mr Journe in the past, I was looking forward to this – and the watch lives up to expectations. The basics of the new model are no surprise, since Mr Journe had let on that the movement will incorporate his signature remontoir. The upgrades to the new movement are sensible both in terms of function and timekeeping. Relying on a single barrel eliminates the finicky and occasionally unreliable double-barrel winding mechanism of the original movement. But the remontoir installed in each going train is the crucial upgrade as it optimises the going trains before and after the escapement. In the original Resonance movement, both balance wheels oscillate at an identical amplitude at any one time, but the am...

Panerai Introduces the Luminor Marina Fibratech PAM 1663 SJX Watches

Panerai Introduces the Luminor Marina Fibratech PAM 1663

Having just debuted a Luminor with fancy “lume” and a sintered titanium case, Panerai is also unveiling another wristwatch in a novel material – the Luminor Marina Fibratech 44 mm PAM01663 with a basalt-fibre composite case. Having been the focus of research in recent years as a lower-cost and ecologically-friendly alternative to carbon-fibre composites, basalt-fibre composites are light, strong, fire-resistant, biodegradable, and more cost efficient, making them increasingly popular in the automotive and aerospace industries. The material starts with basalt rock that’s ground up, melted, and then formed into fibres. As with carbon-fibre composites, the basalt fibres are then mixed in a liquid polymer and baked in a special high-pressure oven, or autoclave, forming the composite material that can be machined to the desired shape. Used for the first time in watchmaking with the Luminor Marina Fibratech, basalt-fibre composite is used for the case and crown-lock bridge, while the bezel, crown, and crown-lock lever are made of carbon-fibre composite (or Carbotech in Panerai parlance), giving the case a two-tone appearance with the carbon-fibre composite several shades darker than its basalt-fibre counterpart. And as is usual for watch cases made of composite materials, the screw-down case back is titanium and screws into an inner case of titanium. Under the titanium back is the P.9010, a thin, in-house automatic with a three-day power reserve. In keeping with current...

Panerai Introduces the Luminor Marina Titanio DMLS PAM01117 SJX Watches

Panerai Introduces the Luminor Marina Titanio DMLS PAM01117

At a glance, Panerai’s latest Luminor unveiled at Watches & Wonders 2020 might look like, well, just another Luminor. But the Luminor Marina Titanio DMLS (PAM01117) is more than that. It incorporates a new type of luminous paint with an extra-bright glow, while boasting a titanium case produced via a process similar to 3D printing. And most crucially, the watch is covered by a 70-year warranty. Given that Panerai’s identity is inextricably linked with legible, glow-in-the-dark dials, the new “lume” found on the Luminor DMLS makes sense. The watch features Super-Luminova X – a lot of it. Beyond the usual dial and hands, the new Luminor also had luminous paint on the flange around the dial, crown locking bridge and lever, and the stitching of the fabric strap. The use of “lume” as a decorative element brings to mind the Lumen series of A. Lange & Söhne (which is a sister brand of Panerai within Swiss luxury group Richemont), but here the luminous paint is executed in clean lines for a geometric pattern. Though the Luminor DMLS is a large 44 mm in diameter, it is only 100 g, making it the lightest Panerai watch with a metal alloy case. The case is produced via direct metal laser sintering (DMLS), the same process to make the case of the Lo Scienzato Luminor 1950 Tourbillon GMT Titanio PAM00578 from 2016. DMLS is a form of 3D printing where a laser is used to melt titanium powder tiny amounts at a time, layer by layer as the case is built up. The nature of the p...

Introducing the Akrivia Rexhep Rexhepi Chronomètre Contemporain “Only Watch” SJX Watches

Introducing the Akrivia Rexhep Rexhepi Chronomètre Contemporain “Only Watch”

Akrivia’s entry for Only Watch 2019 is a unique variant of its critically acclaimed Chronomètre Contemporain but with an added bonus – the platinum case is made by storied case specialist Jean-Pierre Hagmann. The first outing at Only Watch for Akrivia and its founder Rexhep Rexhepi, the unique Chronomètre Contemporain is equipped with a dial made of grey-blue fired enamel featuring white enamel markings. But the dial is unusual for having a hand-hammered finish, a decoration typically only applied to gold dials, giving it a granular surface. The view from the back of the 38mm platinum case is identical to that of the standard model, save for the “JHP” hallmark on the lower right lug. It’s short for Jean-Pierre Hagmann, a semiretired case maker who was responsible for some of the most exquisite watch cases of the 1980s and 1990s. Amongst his work is the incredibly complex case of the Patek Philippe Star Calibre 2000 pocket watch. The Chronomètre Contemporain “Only Watch” is the first watch to emerge from the recently inked collaboration between Akrivia and Mr Hagmann. Stay tuned for more on this. The Chronomètre Contemporain “Only Watch” has an estimate of 40,000-60,000 Swiss francs, and will go under the hammer on November 9, 2019 at Christie’s in Geneva.  The complete Only Watch 2019 collection can be seen on onlywatch.com.

The heart of Panerai’s line-up has to be the entry-level Luminor. A 44mm watch with the classic crown guard-equipped Luminor case and not much in the way of frills. White or black dial, white logo or blue, small seconds or not, and a range of strap options. That’s pretty much it. But you know what? … ContinuedThe post VIDEO: The heart of Panerai – the new Luminor Marina Logo 3 Days in steel  appeared first on Time+Tide Watches.
