In the world of architecture, there are constructs where you ask yourself, how they can withstand the enormous weight by a seemingly fragile method of construction. A similar example from watchmaking has just been introduced by Breguet with their Classique Tourbillon Extra-Plat Squelette 5395, where all supporting elements have been reduced so heavily, that they almost seem not to exist. However, the movement runs as reliable just as the seemingly fragile constructs stand solid as rocks.
Classique Tourbillon Extra-Plat Squelette 5395
In comparison to its two predecessor models from 2013 and 2017, the Classique Tourbillon Extra-Plat has experienced a true metamorphose. Although it has the same case and lug design and pretty much the same movement (calibre 581), yet it is so different. The plate and bridges were skeletonized by 50 per cent and all visible parts guilloched, engraved or chamfered in every detail.
On of the most beautifully skeletonized watches of all
First introduced in 2013, the extra-plat calibre 581 became one of the thinnest automatic movements with a tourbillon at a mere height of 3mm. One way to archive this was to place the rotor peripheral along the plate. A method commonly used in flat watches today. Also the mechanics remains entirely visible. Now, the tourbillon of the new reference 5395 has been revised. A pinion, that was usually mounted on the tourbillon cage has been removed and now engages directly to the wheel train. The silicon escapement has been given a distinct angled shape to better adapt to the flat skeletonized movement.

There are quite some complexities going on in this watch. To start with the flat construction of the tourbillon, that – due to a modernized barrel – reaches an unusual high frequency of 4 Hz and a power reserve of 80 hours. Although the individual movement parts are as light as a feather, the movement needs some stability in order to properly work. The rotor, the tiny meshing gear wheels or the barrel all generate some forces that need to be absorbed somehow. Inside Breguet’s Atelier they have successfully managed to remove as much material as possible without compromising the functionality.
No restricted view – the rotor is placed peripher around the plate
It seems that the craftsmen have literally hold on tight to to the few remaining surfaces. Every visible space has been thoroughly taken care of. ‘Clous de Paris’ hobnailing has been created on the skeletonized plate by a diamond-tipped guilloche tool. The diamond burin is supposed to create an even more distinct splendour. The sharp edges have been chamfered with a file to a 45-degree bevel. The skeletonized movement is bedded into a typical Breguet fluted case and the holes borders have been cut out by hand to frame the 33 jewels and are also chamfered.

We love the blue details: just like the hour markers in blued gold and the Roman numerals that have been applied onto the sapphire glass together with the traditional blued moon-tipped hands and the ‘Breguet’ lettering on the prominent bridge. The platinum version comes with a dark blue strap – it would however also go very well with the rose gold case.

The Classique Tourbillon Extra-Plat Squelette 5395 is a very good example of what the art of skeletonizing really means. With their horological savoir-faire, Breguet succeeded to aesthetically upgrade the rather sober look of a famished movement.

We recently spent a great day with Steve Guerdat, his horses and a historical Oyster Perpetual Cosmograph Daytona at his stables in Elgg, located around 40 kilometers east from Zurich. Not only that Steve is a very pleasant and grounded person, he is also the current world’s best Show Jumper. Although Steve knows much more about horses than…
The new stars at Swiss watch-brand Carl F. Bucherer are not again Hollywood actors or sport enthusiasts as brands usually commit as ambassadors to represent their products, but 188 manta rays! The reason is mainly the brands support in The Manta Trust, a UK registered charity committed to protecting and ensuring the survival of manta rays…
There are brands and manufactures with a clearly louder appearance, however rarely ones with a more sonorous. Jaeger-LeCoultre is an instance in the field of minute repeaters. In 1895, the year the first pocket watch with grand complication was presented, the Jaeger-LeCoultre workshops patented the first so called silent strike regulator. Ever since, around 200…

These days, Vacheron Constantin seems to reach new heights every five minutes. Ever more in the eyes of the public and not just connoisseurs, the horology house recently burst through the billion-franc mark, as it achieved a phenomenal 1.097 billion Swiss francs in sales. According to Morgan Stanley’s annual watch report, this amounts to an average watch…
'Rule number one', declares Audemars Piguet CEO François-Henry Bennahmias, 'Is that the Royal Oak Concept is not your first watch.' Often described as a 'spaceship watch', it stands out for its thick, recognisable, and always balanced architecture. The horology house utilise this watch in order to invent and impress, often using overtly avant-garde design codes.…
To those relatively new to watches, the term ‘independent’ can often appear to be thrown around like a cheap joke on Christmas Day, making them wonder what on earth the term actually means? Patek Philippe and Audemars Piguet are privately owned watchmaking firms and so, at least in a business sense, ought to be considered…
To mark Watches and Wonders 2025, IWC Schaffhausen sets off a veritable display of horological fireworks, not only expanding the Ingenieur collection but also infusing it with a wealth of versatile new models. Five new timepieces – whether in deep black ceramic, featuring a perpetual calendar in stainless steel, or a cinematic limited edition with…
Trends shape the appearance of our society. Whereas recently big case design still dominated the watch landscape – for men as well as for women – the industry now goes back to smaller watch cases. The old shapes do not become superfluous however, because as we all know taste differs and overhauled trends always return. Panerai…
This story begins with a personal anecdote, which at first doesn't appear to have anything to do with Tissot's new Seastar 2000 Professional Powermatic 80. My Seastar from the 1960s is a vintage dress watch. It is so simple and so elegant that actually, I only wear it for important occasions. Tissot Seastar 2000 Professional Powermatic…
Form follows function. This basic principle coming from product-design and architecture might have been the major inspiration for Audemars Piguet when it first designed the Royal Oak collection in 1972. It is such a distinctive design that watch enthusiasts will no doubt recognise this model with a single glance. But what is most interesting to…
Some anniversaries are celebrated with confetti and champagne. Others mark their place in history with an event that redefines their own work. Vacheron Constantin chose the latter for its 270th birthday: the presentation of Les Cabinotiers Solaria Ultra Grande Complication – La Première. A unique piece, a supernova of watchmaking, a new world record for the…
During our last conversation about six months ago, Panerai CEO Jean-Marc Pontroué surprised us with his ambitious intention to launch a 100 percent recycled mechanical watch. Now, shortly prior to the unveiling of the brand's latest pieces at Watches & Wonders 2021, we caught up with him once again. There was one key question to…
