Signatures and Grading

The dial, case, and movement are all signed by Jaeger-LeCoultre, confirming the integrity of the components as a unit. The deployant clasp is also identified as a stainless steel Jaeger-LeCoultre component. The watch is accompanied by a grading evaluation from the auction house. The auction house assesses the case as a grade 3, while the movement is rated as 2*, described as very good. The dial condition is classified as 1-01, denoting an as-new appearance. The watch is sold with its original hands preserved.

Movement and Escapement

The wristwatch is driven by the Calibre 854 movement, a mechanical manual-wind calibre featuring a copper-colored finish. The movement is decorated with fausses cotes and contains 21 jewels. Technical specifications include a straight-line lever escapement and a monometallic balance adjusted to five positions. Performance regulation is handled by a self-compensating flat balance spring. The movement includes a shock absorber system for added durability.

Case and Dial Architecture

The watch features a five-body stainless steel case with polished and brushed finishes. The case is defined by its reversible design and signature reeded bezel, which protects the sapphire crystals on both sides. The case measures 26 mm by 42 mm with a thickness of 10 mm. A side-mounted pusher on the case band facilitates the independent adjustment of the primary time zone display. The primary dial is finished in guilloché anthracite, featuring an off-center ring with luminous Arabic numerals and applied steel dart indexes. A subsidiary 24-hour dial at the 6 o'clock position tracks a second time zone and includes a Night/Day indication. The reverse dial provides a contrast with a two-tone guilloché silver surface, painted Arabic numerals on a plain reserve, and a subsidiary seconds dial.
