Case and Dial Design

The wristwatch is housed in a two-body case made from a mix of stainless steel and 18K yellow gold, featuring a combination of polished and brushed surfaces. The design includes a graduated bezel engraved with radial Roman numerals and the distinctive 'claws' on each side of the case. The case measures 40 mm in diameter and 14 mm in thickness, with a total length of approximately 195 mm. It is finished with sapphire crystals and a screw-down transparent case back to view the movement. The dial is finished in a satine silver tone, featuring applied yellow gold baton indexes and luminous square markers for visibility. Time is indicated by luminous yellow gold dauphine hands. The dial layout includes two specific calendar apertures: a day-of-the-week display positioned at the 12 o'clock index and a date display positioned at the 6 o'clock index.

Signatures and Grading

All primary components of the watch—the dial, the case, and the movement—are signed by Omega. The case bears the serial number 85944312. The watch is classified as a chronometer and is noted for its center seconds function and water resistance rating of 100 meters. The auction house has assigned a grading system to the lot. The case is graded as '1' (as new), and the dial as '1-01' (as new). The movement is graded as '1*' (as new). The watch is accompanied by an integrated Omega link bracelet in stainless steel and 18K yellow gold, which features a double deployant clasp.

Movement and Escapement

The timepiece is powered by the Omega Caliber 8602, a self-winding, automatic movement. The movement is rhodium-plated and features fausses côtes decoration. It is designed as a chronometer, incorporating a co-axial escapement intended for precision timekeeping. The technical assembly of the caliber includes a monometallic balance equipped with timing screws for calibration. It further utilizes a shock absorber system and a free-sprung self-compensating flat balance spring to manage oscillations.
