“How can you remove a pushbutton or function corrector, without removing the function?” Such was the brief given to the technical teams of Dubois Dépraz in the spring of 2021.
The quest for simplicity is a challenge with which the teams at the Manufacture in Le Lieu are frequently confronted, whether in developing their own designs or meeting specific customer requirements. The specifications were then complemented by the desire expressed to be able to apply the solution found to a highly sought-after watchmaking complication: the dual-time indication commonly known as GMT.
The result is undeniably innovative and worthy of Dubois Dépraz’ creative reputation. For the new DD360 Gravity, a single pusher is sufficient to adjust the second time zone. An energetic rotation of the wrist enables selection of two different functions for one and the same pusher. One can thus choose to move the local time hand forwards or backwards when travelling. An indicator on the dial shows in which direction the adjustment will be made – a simple and ingenious solution.
Home time is displayed by a central 12-hour hand combined with a day/night indicator in an aperture at 9 o’clock. It is located below the one indicating the local time. This design enables these two hands to be perfectly superimposed when the wearer is not travelling, a detail appreciated by purists.
The date display is linked to the local time display. When the time zone is adjusted past midnight, the date jumps in either direction. Based on a Sellita SW300 movement with a power reserve of approximately 56 hours, the new DD360 Gravity has a diameter of 30mm and a thickness of 1.60mm (5.20mm with the base movement). All steel parts are single-thickness, a fact that facilitates decoration. The calibre is also adaptable to any Manufacture movement.
