Object description

Case and Construction

The watch is housed in a stainless steel, tonneau-shaped case measuring 42 mm in diameter. It incorporates a water-resistant construction secured by a screwed case-back. To mitigate the effects of magnetic fields on the timekeeping, the movement is enclosed within a soft iron calotte or protective inner container.

The bezel is fixed and features a tachymeter graduation, allowing for speed calculations up to 500 units per hour. The case design incorporates round push-pieces for the operation of the chronograph functions.

Movement and Chronograph Functions

The timepiece is powered by the manual-winding caliber 861. The movement is responsible for the timekeeping and the three horological complications designated for the chronograph. These include the 1/5 second central sweep seconds hand, a 30-minute recording dial at the 3 o'clock position, and a 12-hour recording dial at the 6 o'clock position.

The 30-minute recorder functions as a half-instantaneous mechanism, while the 12-hour recorder operates via a dragging mechanism. The movement remains protected by the internal soft iron housing as noted in the physical construction documentation.
