De Bethune Introduces Custom Regulation with the Sensoriel

De Bethune’s latest invention aims to customise the regulation of a mechanical watch to suit the individual owner. Dubbed the Sensoriel Chronometry Project, it takes the form of a electronic wrist instrument that measures the wearer’s activities and environmental conditions over a two week period – gathering two million data points per hour according to the brand. With this voluminous quantity of data, De Bethune will then regulate a DB28GS Grand Bleu sports watch specifically for the particular owner, optimising timekeeping based on the wearer’s activities. [Updated to include response from Denis Flageollet.] Initial thoughts On paper the Sensoriel is interesting and impressive, but on reflection it raises several questions. For one, the two million data points recorded per hour – for a two-week period – results in an extraordinary amount of information on the wearer’s activities. Can any mechanical watch be regulated to a fine enough resolution that makes even a fraction of that data useful? My knowledge of watchmaking is certainly inexpert but I am sceptical. Mr Flageollet points out De Bethune utilises an algorithm to process the data and sieve out the “elements specific to the wearer, in a way to bring out a specific chronometric DNA for each wearer”, allowing the watch to be regulated according to a smaller number of data points. The second salient point is more philosophical. Historically the pursuit of chronometry meant good timekeeping regardless...

OK, cool… But who is the new 50mm titanium Rolex Deepsea Challenge really for?

Today, inspired by the experimental watch that accompanied filmmaker James Cameron on his historic 10,908-metre (35,787-foot) descent into the Mariana Trench on March 26, 2012, Rolex has revealed their first ever all-titanium production watch: the Rolex Oyster Perpetual Deepsea Challenge in RLX Titanium with a depth rating of 11,000 metres.  As cool as it is to … ContinuedThe post OK, cool… But who is the new 50mm titanium Rolex Deepsea Challenge really for? appeared first on Time+Tide Watches.

Panerai Introduces the Luminor BiTempo PAM01360 and PAM01361

Traditionally all about vintage-inspired, “Marina Militare” dive watches, Panerai has recently been rolling out complications with a minimalist, contemporary execution, such as the recent Luminor pepertual calendar. Sharing a similar aesthetic perhaps more practical – and certainly more affordable – is the new Luminor BiTempo PAM 1360 and PAM 1361, a GMT wristwatch with striking baby-blue accents on a blue or black dial. The PAM 1361 with a radially-brushed blue dial Initial thoughts Given its large diameter and clean dial, the Luminor accommodates complications well while still maintaining its characteristic minimalist style – if the additions are integrated properly. Panerai managed that with the BiTempo, which manages to incorporate a date, second time zone, and power reserve indicator without hindering the recognisable Panerai aesthetic. In fact, the BiTempo could pass for a time-only Luminor from across a room. That said, the second time zone isn’t a new complication for the brand – the movement is an existing calibre – so the novelty is mainly in the facelift that changes dial details like the enlarged date display and blue accents. While I appreciate that the baby blue indicators are legible, I find the colour overly pastel for the low-key, military-inspired styling. Legible both day and night Twin time zones The BiTempo has a 44 mm Luminor 1950 case with its trademark crown guard. The “sandwich” dial has the signature Luminor layout with ov...

The Polaris Mariner is a range of high-performing diving watches that pay homage to the brand’s diving legacy and almost 100 years of knowledge and expertise on chiming watches. Jaeger-LeCoultre has introduced two watches to their sporty and elegant Polaris collection; the Polaris Mariner Memovox and Polaris Mariner Date. What we have on our hands today is the classic diving piece the Jaeger-LeCoultre Polaris Mariner Date.  Case: Reference : 9068180 The case on the new Jaeger-LeCoultre Polaris Mariner Date is as close as it gets to the vintage 1968 Memovox Polaris.

With the latest Polaris Mariner Date model, the alarm and sound transmission mechanisms have been left out for the Memovox model, with the Mariner Date being the simple yet classic diving...

The Jaeger-LeCoultre Polaris Mariner Memovox doesn’t just sound as good below water as it does above, it sounds even better! While many of the recent Memovox models have been unashamedly contemporized, the Polaris Mariner Memovox is a relatively faithful tribute to the original 1965 Polaris.

Underwater, accomplished and amateur divers alike need to rely on equipment that is impeccable both in terms of precision and safety.

When Accuracy Mattered - Part III: The Triumph of Brands Over Watchmaking

The demise of chronometry competitions last year – when the final edition of Concours International de Chronométrie took place – finally killed the dangerous heresy that a watch is a practical instrument that should be trusted to show the correct time. With the elimination of the last scientific and independent assessment of a watch’s worth, the cult of haute horlogerie comes into its own, reinforcing its definition of a watch as an emotional product born of passion, tradition and prestige. Trials to see who can produce the most precise, accurate and reliable watch originated in Geneva in 1879, when the head of its observatory, Professor Emile Plantamour, devised a testing routine that rated watches in the various positions and temperatures encountered in everyday wear. Observatories soon became the influencers of the pocket-watch age, determining the legitimacy and worth of luxury timepieces. American magnates like James Ward Packard, Henry Graves Jr and Pierpont Morgan secured the most highly rated pieces. A Longines split-seconds chronograph pocket watch that was tested at the Neuchatel Observatory in 1968; this particular example once belong to Jean Pitallier, the former president of the French Cycling Federation (FFC) Despite the advent of wristwatches, the Neuchatel Observatory kept the competitions alive until 1968 when Japanese entrants swept the board. In 1972, deputation of Swiss watch brand executive petitioned the Neuchâtel government minister Ren...

MB&F; and Massena Lab Introduce the T-Rex Bronze SJX Watches
Massena Lab Introduce Jul 30, 2020

MB&F; and Massena Lab Introduce the T-Rex Bronze

Massena Lab was founded by watch industry veteran William Rohr – who is better known by the pseudonym William Massena – in 2018, with the purpose of collaborating with notable independent watchmakers, and perhaps one day make its own watches. Having made its debut with Habring2 , Massena Lab has just announced the T-Rex Bronze, a 15-piece variant of the quirky MB&F; table clock launched last year. Best described as a hand-blown Murano glass eyeball inside a bronze socket with legs, the T-Rex is made by L’Epee 1839, who is also responsible for all of MB&F;’s other clocks. Initial thoughts The T-Rex is an offbeat, statement piece for the desk, but powered by old-school mechanics – a key-wound, eight-day movement made by L’Epee 1839, a clockmaker founded in, well, 1839. That blend of contemporary creative and classic mechanics makes it cool. But the Massena Lab edition is a departure from the usual MB&F; clock style, which is dominated by metallic silver or black, resulting in a highly mechanical look. The Massena Lab T-Rex replaces the steel of the original version for frosted bronze and “aged” feet, giving the clock a striking, steampunk aesthetic. Permanent patina Standing a little under 27 cm high, the T-Rex weighs about 2 kg. According to MB&F; founder Maximilian Büsser, the form was inspired by a bipedal Christmas ornament on his desk. Freelance watch designer Maximilian Maertens then created the clock, relying on images of an actual Tyrannosaurus Rex to d...

Panerai Introduces the Luminor Blu Mare 44 mm PAM01085

Perhaps the most recognisable Panerai is the Luminor Marina 44 mm. A modern-day creation inspired by a vintage military-issue watch, the Luminor Marina was introduced in 1993, and a decade later became one of the watches that kickstarted the fashion for bigger watches. While the Luminor Marina was historically all about black dials for a no-nonsense military look, Panerai has been injected more colour into the line up for a civilian-friendly style. The new Luminor Blu Mare 44 mm PAM01085 – blu mare translate as “blue sea” – retains the traditional design codes of the Luminor plus a fashionable blue dial. Initial thoughts While earlier Luminor models like the PAM1663 and the PAM1033 have had blue dials, but the new Luminor is arguably the cleanest, harking back to the entry-level Luminor Marina “Logo” of about a decade ago. The blue is metallic, subdued and finished with a radial-brushed finish that’ll definitely catch the light nicely. A colour that’s been in vogue for a couple of years, the blue dial gives the Luminor Blu Mare a slightly more elegant and contemporary feel than the typical Panerai, a useful quality for someone who likes the functional Panerai design but prefers lighter colour palette. The design, however, is strictly traditional. With the vintage originals designed as functional instruments for navy frogmen of the Second World War, the new Luminor is expectedly utilitarian, with large, eminently simple hands and indices – very much the ...

Ian Skellern still remembers the sense of awe he felt when he had the opportunity to watch and listen to a recently restored centuries-old Jaquet Droz singing bird. The animation was compelling, and the quality of the birdsong sound was incredible. But as impressive a feat he thought that full-sized eighteenth-century Jaquet Droz singing bird clock was, shrinking that mechanical technology to wristwatch size is just mind-blowing.

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

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...
