Object description

Case and Dial

The watch features a two-body case construction measuring 34 x 35 mm with a thickness of 11 mm. The case is finished in both polished and brushed surfaces, with a stainless steel screwed-down case back. It incorporates a wide bezel, curved lugs, and a winding crown positioned at the 4 o'clock side. The minute repeating mechanism is operated via a slide integrated into the band of the case.

The off-white dial displays applied steel Breguet-style numerals and a perimeter minute track. A specific sector for the defiling digital jump seconds is positioned directly below the 12 o'clock hour marker. The time is indicated by steel Feuille-style hands, providing a contrast to the lighter dial background.

Movement and Functionality
