It is one of the simplest and most spectacular horological complications at the same time. On a dial, a retrograde movement can be identified when the hand indicating a time measurement moves on a semi-circular scale or a section of a circle.
The main visual appeal of this display is the instantaneous return of the needle to the starting point, when it reaches the end of the scale. A leap back which we watch for the next trigger. The wait is more or less long depending on whether it is a window for seconds, minutes or a power reserve (1), a second time zone… or even the day of the week or the date. A so-called “retrograde” mechanism is used to display different temporalities, with as many aesthetic variations.
Thirty minutes in an arc
Centuries-old watchmakers, such as Vacheron Constantin, have made it a signature. During the Watches and Wonders trade show in Geneva, the manufacture also unveiled three new models fitted with retrograde hands in its Heritage, Overseas and Traditional collections.
Jaeger-LeCoultre, with the intention of balancing the legibility of the circular time display in the rectangular case of the Reverso Tribute Chronograph, has positioned a retrograde thirty-minute indicator in an arc of a circle at 6 o’clock.
A much more recent house – it was created in 2017 –, Reservoir has always been faithful to a retrograde minute display, combined with a jumping hour.
Hublot goes even further with its Tourbillon Bi-Axis Retrograde, which combines a tourbillon with a bi-retrograde movement for the hours and minutes. Despite the complexity of this reference, reading the time remains intuitive.
