The Tonda GT Chronograph features a 42-mm case, forged in polished and satin-brushed stainless steel and boasting a water resistance of 100 meters. Its silver-and-black dial adorned with clou triangulaire texture has rhodium-plated indexes treated with black luminescent coating. Like its predecessor with a black dial, the watch houses the automatic Caliber PF043. Though the watch’s name indicates that it is a chronograph, it is actually something much more special, as Caliber PF043 enables the rare horological pairing of a chronograph with an annual calendar.
