The DualTow watch was created to celebrate the 20th anniversary of Le Locle-based manufacture, Christophe Claret. This 3D high-definition video shows off the watch’s impressive innovations and features.
The most innovative attribute is its unique single-pusher planetary-gear chronograph with a striking system. A single-push piece activates three identically structured planetary gears that control the chronograph functions. A patent has been filed for this original interpretation of the chronograph.
As if that is not enough, Christophe Claret has chosen to add a striking mechanism signaling when the chronograph is started, stopped, and reset. Placed on either side of the dial are belt-type displays. Hours are displayed on the left belt and minutes on the right. A fork was added to serve the time. This unprecedented mechanism is exclusive to Christophe Claret.
At 6 o’clock lies a visible 60-second tourbillon. A tourbillon would normally be one of the most important complications on a timepiece, but in this case, the planetary-gear chronograph and belt-type display steal the show.
The case is fitted with moving lugs to enable fine adjustment to the shape of the wearer’s wrist. The DualTow case features sapphire crystals on four sides. One on the dial, one on the back, one on the left-hand side, and one on the right – between the pushers and the crown.
The crocodile leather or rubber strap of the DualTow is equipped with an exclusive adjustable clasp, enabling the wearer to extend it easily by as much as one centimeter. This comfort-enhancing feature guarantees an optimal fit.
Quite an amazing piece. Only 68 pieces will be available worldwide. Each piece is unique and has multiple customization options.
