Object description

Case and Dial Design

The watch is housed in a polished, three-body cushion-shaped case measuring 45 mm by 45 mm, constructed in stainless steel. The design includes a transparent screw-down case back allowing visibility of the movement, and it utilizes sapphire crystals. A notable structural feature is the set of wire lugs, which are secured to the case band using four individual screws.

The black dial features luminous Arabic numerals and index markers. It contains two subsidiary dials: a 30-minute register positioned at the 3 o'clock mark and a 1/8th-second register located at the 9 o'clock position. The dial also displays an outer 1/5th-seconds track and a tachometer scale capable of measuring up to 400 UPH, complemented by luminous steel baton hands.

  • “Black with luminous Arabic numerals and indexes, subsidiary dials for the 1/8th seconds at 9 and the 30-minute register at 3”

Movement and Functionality

The timepiece is powered by the caliber OP XVI, a self-winding mechanical movement. The movement finish includes rhodium-plating and an oeil-de-perdrix decoration. It utilizes 40 jewels and includes a straight-line lever escapement with a monometallic balance and a shock absorber system. The regulation is managed through a micrometer regulator and a self-compensating flat balance spring.

The watch functions as a 1/8th split-seconds chronograph. Operational control is provided by a screw-down winding crown, which uniquely features an integrated co-axial push button specifically for the split-seconds function.
