Let’s take an eye on the Dewitt Tourbillon Force Constante à Chaîne watch today. There is a question as old as the historic horology: how can one ensure the perfectly regular transmission of energy to the mechanism. This vintage question requires technically complex answers. As known to people in-the-know, the energy, generated by the mainspring, is transmitted according to the degree of winding of the barrel. That is to say, the barrel-spring supplies a steadily diminishing amount of energy as it uncoils. This fact definitely affects the movement’s reliability and precision. No concept has given a better solution than Dewitt to this problem, one of the uppermost subjects of endless research since the 17th century.
The brilliant watchmaking company Dewitt presented its revolutionary Tourbillon Force Constante watch in 2006 (see the video). As a glorious pioneer in the pursuit of the perfect fusion of magnificent horology and modern technology, the watch emblemed a milestone development in the watchmaking history, offering a satisfying answer to the aforementioned question.
Dewitt solution consists in providing perfectly constant power by an independent device, an additional mechanism inserted into a traditional mechanical movement. The device absorbs the force generated by the barrel once every second and redistributes it to the tourbillon every 10 seconds. Comprising three additional wheels: one to ensure correct gear operation; and two intermediate wheels between the motive force (barrel) and the regulator (tourbillon), the innovative mechanism also features its own balance-spring, enabling the mainspring to be constantly supplied with a level of energy superior to that required by the tourbillon regulator (patented by DeWitt). With this excellent solution, the motive power has been exchanged and the watch is allowed to receive constant impulses whose energy remains identical and regular, however taut the barrel-spring is.
Now the exceptional Tourbillon Force Constante is enriched by a new watch – the Tourbillon Force Constante à Chaîne. The new watch has its own name, one embodies innovation beyond a dream. The chain, adopted to break free from the collection’s marvelous inheritance, represents a new system that serves to relay energy to its associated power reserve indicator. When the wearer turns the watch’s crown to wind the barrel-spring, a diminutive chain is driven. It uses an intermediate wheel to activate the power-reserve indicator sliding on a worm screw. If the pointer is in the red zone, the power-reserve is close to zero; when it is in the green zone, it means the barrel-spring is sufficiently wound.
The 43mm case, crafted in 950 platinum, houses the hand-wound DW8050 caliber movement. The watch comes with a power reserve of 72 hours. Functions include hours, minutes, as well as a power reserve indicator. There is a black alligator leather strap, fitted with a folding clasp, in 750 platinum. The Dewitt Tourbillon Force Constante à Chaîne stands for a bridge between a glorious past and a promising future, just as its embodiment – innovation beyond a dream.
