A timeless design

Well balanced and symmetrical design with a convex shape dial to align with the shape of the case. Perfect readability: “baton-type” applied hour-markers and polished, leaf-shaped minute and hour hands.

The Calibre GP03300

The Calibre GP03300

A GP unique patented large date: this unique date is displayed by means of two extremely thin disks, one for the tens, and the other for the units so that there is no visible separation between the numerals. To be almost invisible, the transparent disc is extremely thin: only 0.10 mm thick. The date change is instant, taking only one ten-thousandth of a second.
