Ahead of the SIHH 2018 salon in Geneve, the house of DeWitt presents the Academia Endless Drive, equipped with a rotating endless screw that can be admired at the center of the dial. Endless screw, an obvious nod to the world of automotive mechanics, is fixed so that it can’t move longitudinally as it rotates. Instead, this stationary screw forces the mechanical part to advance. As explained by DeWitt’s founder Count Jérôme de Witt, the curves of the screw in unidirectional movement symbolize irreversible rotation, which is, by itself, an allegory for the passage of time.
This interesting new model, which will be first revealed at the Salon International de la Haute Horlogerie in Geneva, taking place from January 15th to 19th, is powered by a rare winding mechanism that confers an unusual movement to the helical screw linked to the winding system. As the amount of remaining stored energy (60 hours) decreases, the screw rotates. Once the barrel is fully wound, the endless screw slides on its longitudinal axis.
This elegantly proportioned timepiece is crafted from 18-karat rose gold and it measures 42.5 mm in diameter and 12.8 mm in thickness. The case is adorned with DeWitt’s emblematic imperial columns on its sides, and fitted out with double sapphire crystals. The black galvanic dial features silvery-white sub-counters with contrasting rose gold details and indicators. The time is indicated via two discs, located at 9 and 3 o’clock position. The hours and minutes are shown separately – minutes to the right, and hours to the left.
DeWitt Academia Endless Drive is powered by the automatic in-house caliber DW1653. The movement, mounted on 21 jewels, beats at a frequency of 21,600 vibrations per hour offering at least 60 hours of power reserve. The power reserve indicator is visible on the dial side, just above the endless screw.

Latest News from DeWitt
Dewitt Academia Sparkling Out of Time
Manufacture DeWitt was established almost 15 years ago by Jérôme de Witt, in continuation of the successful Swiss luxury watch brand Cédric Johner. This high-end watchmaker prides itself in being one of the 18 watchmaking brands that is capable of producing their own movements, and one of the four luxury brands with in-house dial makers. DeWitt watches are immediately distinguished for their avant-garde design with gear-shaped sculpted bezels modeled after the famous 24 "imperial columns." The brand offers six different product ranges, includin...
DeWitt Academia Mathematical
The DeWitt Academia Mathematical, a watch introduced at BaselWorld 2015, is DeWitt’s fourth concept watch. This imaginative automatic timepiece is inspired by historical mystery watches, on which certain components are hidden from the eye of the observer, so it appears like hands are floating freely above the dial, without any obvious connection to the movement. On the mystery watches, the movement is transmitted to the hands through an invisible wheel, which is typically made of transparent sapphire. In its modern-day variant, the mystery w...
DeWitt Blue Empire
The Blue Empire range comprises four different versions of simple and sophisticated timepieces adorned with diamonds and delicate feminine details. These gorgeous, slender watches are available in 36-mm diameter cases, crafted in either 18-carat rose gold or 18-carat gold and steel. Each of the gorgeous four watches is finished with a luxurious metal wristband with jewelry fastenings, while the wristband of the rose gold model features a strip of round diamonds at its center. DeWitt Blue Empire is named after its midnight blue dial finished...
DeWitt Twenty-8-Eight Skeleton Tourbillon 2015
The Twenty-8-Eight range is a tribute to Jérôme de Witt’s illustrious ancestor, Napoleon Bonaparte, and it epitomizes expresses the brands creativity and watchmaking excellence. The range comprises all the Tourbillon movements produced by DeWitt, including mechanical, automatic and skeleton movements. In the spirit of haute horlogerie, each of these movements bears a signature of the watchmaker who personally assembled it by hand. The newest addition to the range - DeWitt Twenty-8-Eight Skeleton Tourbillon – is a manually wound tourbillon calib...
DeWitt Academia Out of Time Unique Piece for Only Watch 2015
The house of DeWitt is showing its support for the sixth edition of the Only Watch charity auction. The event, which benefits scientific research on Duchenne muscular dystrophy, will be held on the 7th of November 2015, in Geneve. Same as all other contributors, DeWitt has created a special, one-off timepiece which will be offered at auction to support research into this serious degenerative disease. The biennial event is held under the patronage and in the presence of HSH Prince Albert II, and DeWitt has participated ever since 2005. For th...
DeWitt Academia Chronostream II
The new member of the DeWitt's Academia collection is yet another example of timelessly elegant masculine timepieces inspired by the sporting world. Same as all other creations belonging to this range, the new Chronostream II features an relentless avant-garde design, and a distinctively sculpted bezel evocative of the famous 24 imperial columns - a nod to the noble origin of DeWitt's founder Jérôme de Witt, who is a direct descendant of emperors and kings in Europe, including the Emperor Napoléon. As announced by the brand, the new DeWi...
Dewitt Twenty-8-Eight Tourbillon 015 and 016
This unique watch is dedicated to Monsieur Jérôme de Witt’s famous ancestor, Napoleon Bonaparte, and it was conceived and sketched on the same date when Napoleon was given the title Emperor by the French Senate and was crowned emperor of the French. The new model is powered by the calibre DW8028, which features the very first tourbillon movement entirely developed and produced by the DeWitt Manufacture. The watch is available in two different variants and produced in limited editions of 99 pieces each. The styles available are 18-carat pink...
DeWitt Twenty-8-Eight Seconde Retrograde
DeWitt’s fabulous Academia Seconde Retrograde, one of the main models of DeWitt watch collection, was launched in 2003. Now almost 10 years after, the manufacture releases new Seconde Retrograde watch, which is now presented in a more classical, more slender Twenty-8-Eight case. The new edition pays a tribute to the famous Academia Seconde Retrograde watch, a piece that significantly contributed to the growing popularity of the brand, being one of their first bestsellers. DeWitt Twenty-8-Eight Seconde Retrograde watch is crafted in 18-carat...
DEWITT Twenty-8-Eight Skeleton Tourbillon
The watch is going to be officially unveiled at this year’s BaselWorld, showing that - this time - the brand puts an emphasis not on a dial but on the superior in-house movement nested inside 43 mm-diameter case. The dial is fully skeletonized to reveal DeWitt’s historical DW8028, which is actually the first 100% manufacture movement. Generously decorated in the spirit of haute horlogerie, the mechanism boasts the escape wheel and the anchor that are made of 18-carat yellow gold. It beats at 18’000 vibrations per hour and ensures 72 hours of...
DeWitt X-Watch - Only Watch 2011
This is a lively and playful piece, designed in the manner of reversible watches. DeWitt X-Watch features “bonnet” in the shape of an “X” that partly covers the face of the watch. Four push-pieces, positioned at the upper and lower edge of the case, are used to separate the middle and slowly open up to reveal a face of a watch. Only in this position the wearer can flip over the case and lock it up again. However, the watch will continue to serve its inner purpose even when the bonnet is in the closed position, and will remain completely readabl...
