- Case and Dial Design
- The timepiece features a large-format three-body case measuring 45 mm in diameter, manufactured from 18K yellow gold. The construction includes polished surfaces, lapidated lugs, and a bi-directional rotating bezel, which provides the necessary mechanism for operating the integrated slide-rule function. The design also incorporates a helium escape valve and a screwed-down case back, the latter of which bears an embossed Bentley logo. The dial uses a bi-color black and matte silver configuration. It displays subsidiary registers for 12-hour and 30-minute intervals and a small seconds indicator. Hour markers consist of yellow gold indexes paired with luminous square dots, matched by luminous 'bâton' hands. A date aperture is positioned between the 4 and 5 o'clock markers, while the periphery of the dial includes both the tachometer scale and the revolving slide-rule graduations.
- Movement and Mechanics
- The watch is driven by a rhodium-plated Calibre 25 movement, which is self-winding and features 38 jewels. The mechanical structure includes a straight-line lever escapement and a monometallic balance. To ensure chronometric precision, the movement is equipped with a self-compensating flat balance-spring, a micrometer regulator for rate adjustments, and an integrated shock-absorption system. The movement is signed by the manufacturer, consistent with the signing found on the dial and case. It functions as an officially certified chronometer, reflecting the manufacturer's standards for precision timekeeping. The watch is designed for water resistance, supported by the use of a screwed-down crown and case back.
- Provenance and Production
- This watch was produced in 2003 as part of a special edition series. The production was intended to acknowledge two specific corporate associations: the celebration of the collaboration between Breitling and Bentley, and the commemoration of Bentley’s involvement in the 24 Hours of Le Mans endurance races. The timepiece is categorized as an oversized wristwatch and is supplied with a fitted box and a certificate of authenticity. The auction description assigns specific grading levels to the case, dial, and movement, characterizing the overall condition as very good.
