How many dial makers were used by Rolex for the series 16500?

Rolex employed four different manufacturers: Singer at La Chau-de-Fonds for lacquered and galvanised classical models, Beveler in Geneva for lacquered and galvanized dials and also some short series of jewelry models; Stem in Geneva for their creations in semi-precious stones, mother of pearl and pave brilliants, Lemrich in La Chau-de-Fonds,

On the dials of the series 16500, the 12 is replaced by the logo and is surmounted by the inscription giving the specifics of the watch. The Rolex logo is identical for all dials even though they were produced by four different manufactures. The rings of the totalizers are available in the least two sizes, narrow or wide fonts and writing position changes.

At the end of the 1980s the process for affixing the name Rolex and the technical characteristics change. The transferring plate is no longer hand-engraved, instead an acid process is used with allows a better quality even in the slightest details.

For the Cosmograph (series 16500), Rolex offered a vast choice of colors and iconography.

The inscriptions appear in a variety of ways since Rolex always looked for ways vary their position so as to obtain a graphically perfect dial.

For the classic models, the background … Continue reading...

Different types of buttons in Rolex Daytona

In this short article, we want to show you the different button models of Rolex Daytona. They are divided into four generations, the first of which is the simplest for the model.

References 6239, 6241,6262 and 6264 have pump 24-P3 push buttons. For these references, one sometimes also finds replacement pressure-proof screw-down push buttons, possibly fitted during a maintenance service in order to improve the water-tightness of the case.

References 6240, 6263, 6265, 6269 and 6270 have pressure-proof screw-down buttons (1964 Rolex patent). There are three generations of pressure-proof screw-down push buttons: the first with knurled buttons, nicknamed “Milerighe” by collectors, fitted on reference 6240 and only initially on the references 6263 and 6265: the second and third with fluted buttons of the 24-P301 and 24-P302 type for references 6263, 6265, 6269 and 6270.

It is important to note that during maintenance services, Rolex often used to replace knurled “Millerghe” buttons by factory-mode spare-part fluted buttons, which were more user-friendly. Rolex uses the expression “pressure-proof screw-down push buttons” to refer to its water-resistant screw-down push buttons.

Rolex Daytona parts – You can found dials, bezels, buttons, crystals, crowns and etc.

Porsche Design 1919 Globetimer UTC

At first glance the Porsche Design 1919 Globetimer UTC looks like a chronograph, with two pushers on the right side of the case. But here the pushers don`t activate a stopwatch but instead control a time-zone function. This is unique in the watch world. The Porsche principle has been integral ever since the founding of Porsche Design Timepieces AG in Solothurn, Switzerland, in 2014. Watch research, design and production are all under the company`s own control while consistently maintaining a direct link to the sports car manufacturer and the engineers at Porsche Motosport.

Caliber 04.110 is based on a Sellita SW200, with the addition of an exclusive Dubois Depraz module and distinctive Porsche Design finish.

This symbiotic relationship is often seen but has never been as clearly defined and direct as it is today. The first Porsche Design watch came onto the market in 1972 – the year Proffesor Ferdinand Alexander Porsche founded the Porsche Design lifestyle brand with the vision of extending the Porsche legend beyond the limits of the automobile. For the father of the 911, it was clear that based on the dashboard of the car, this watch had to be a chronograph with a black dial. … Continue reading...

The Delicate Sound of Thunder – MB&F World’s Fastest Triple-Axis Escapement

MB&F`s new Legacy Machine Thunderdome features a world-first, proprietary tourbillon device and also marks the first collaboration between watchmakers Eric Coudray and Kari Voutilainen.

The heart of the latest piece in Bussser`s popular Legacy Machine series is the so-called TriAx tour-billon mechanism designed by Coudray, developer of, among other standout high complications, Jeager-LeCoultre`s Gyro-tourbillon. It replaces the traditional but more cumbersome system, which links one tourbillon cage with each rotating axis, with a three-axis, two-cage configuration that allows for maximum visibility of the tourbillon escapement`s beating heart – all under a large domed sapphire crystal that gives the model its cinematic, sci-fi nickname. Off-center at 6 o`clock is an analog subdial with Roman numerals on which the watch tells the time with two blued hands.

To control the rate of energy escaping from the movement`s barrel, MB&F and Coudray opted for a so-called Potter escapement, named after 19th century watch-maker Albert H. Potter, which is notable for its use of a fixed escape wheel rather than the more common, mobile wheel.

This combination of a fixed wheel within a tri-axial mechanism, has never been used in watchmaking before. It allows for higher rotational speeds for the cages – the … Continue reading...

Steel Watches A 20th-Century Phenomenon

Of all the materials used to make watches, steel is unique in its ability repeatedly transcend its lowly status.Watches made from gold, platinum, ceramic, carbon composites and titanium fetch higher prices new, yet new steel watches from high-end brands remain impossible to get, while vintage steel watches continue to top auction house records.It’s downright counterintuitive. Understanding why vintage steel watches have become so valuable is a bit easier than grasping why new ones command prices well above list on the secondary market, but, as we will see, the two phenomena are intertwined.

Stainless steel didn’t become a commercially viable material until early in the 20th century. Europeans led the way, eventually developing corrosion-proof steel alloys. How ever, few watch manufacturers had the tools to effectively machine this incredibly hard material, and finishing steel was still a nascent artform. Even into the early 1960s, less expensive watches were typically made from bass and then plated in chrome. Steel watches remained the thing of military contracts and highly specific tool watches, like divers, pilots’ chronographs and GMTs, as well as waterproof expedition-ready timepieces. Furthermore, most of the steel watches made before the 1970s were not fashionable. The mid-20th century was a time … Continue reading...

A very British story

The Double Impulse Chronometer, the first wristwatch completely made in England in more than half a century, has thrust the old firm Charles Frodsham & Co. into the spotlight.

-Charles Frodsham & Co. makes the most interesting chronometer wrtistwatch you have never heard of. The above statement is anachronistic, especially at a time when social media has given every brand a pulpit to preach to the choir. But then Frodsham, which can claim to be the oldest continuously trading firm of marine chronometers in the world today, has never really believed in putting itself out there. “We are not a brand, we don’t do social media. We have no PR and marketing. We let other people do the talking on our behalf,” says Richard Stenning, who along with his partner Philip Whyte run the firm today after having bought it in the mid-1990s. While you can appreciate the discrete manner in which they go about their business, as soon as their first wristwatch – the Double Impulse Chronometer – broke cover last year, literally anyone who had more than a passing interest in fine watchmaking and horological history was talking about it. “We didn’t quite realize the impact that it … Continue reading...
