Jaeger LeCoultre Reverso Duo Face Night Day

Partially verified

This Jaeger LeCoultre Reverso Duo Face Night Day is a reversible rectangular wristwatch in 18K yellow gold, manufactured circa 2000. It features a five-body solid case with a reeded bezel and an 18K yellow gold deployant clasp. The watch is powered by a copper-colored Caliber 854 movement, which includes 21 jewels, a straight-line lever escapement, and a monometallic balance adjusted to five positions. A push-button on the case band allows for individual adjustment of a second time zone. The timepiece displays dual dials: a front silver guilloché dial with painted Arabic numerals and subsidiary seconds, and a back anthracite guilloché dial with a 24-hour subsidiary dial and luminous indexes. Both the dial and movement are signed by the maker. Measuring 26 x 42 mm with a 10 mm thickness, the watch uses sapphire crystals for both faces.

Object description

Case and Dials

The watch is housed in a five-body, 18K yellow gold rectangular case, finished with both polished and brushed surfaces. It is characterized by its signature reeded bezel design, a hallmark of the Reverso series, and is secured to the wrist with an 18K yellow gold deployant clasp.

The timepiece offers two distinct dial faces. The front dial is crafted in silver guilloché, featuring painted Arabic numerals and a subsidiary seconds dial at the base. Conversely, the reverse side presents an anthracite guilloché dial, which includes a 24-hour subsidiary indicator, luminous Arabic numerals, and faceted white gold dart indexes for increased legibility. Both sides are protected by sapphire crystals.

Evidence for this section
  • “Five-body, solid, polished and brushed, reeded bezel”
  • “Front: guilloche silver with painted Arabic numerals on a plain reserve, subsidiary seconds dial.”
  • “Back: guilloche anthracite with luminous Arabic numerals and faceted white gold dart indexes, subsidiary 24-hour dial.”

Movement and Functionality

Powering the watch is the Caliber 854, a manual-winding movement featuring a distinctive copper-colored finish and fausses cotes decoration. The movement incorporates 21 jewels and operates via a straight-line lever escapement. Accuracy is maintained through a monometallic balance that has been adjusted to five positions, complemented by a shock absorber system and a self-compensating flat balance spring.

The watch is designed to track two distinct time zones, which can be adjusted individually. A specific push-button located on the case band serves as the mechanism for advancing the second time zone, allowing the wearer to manage local and home times simultaneously through the dual dial configuration.

Evidence for this section
  • “M. Cal. 854, copper-colored, fausses cotes decoration, 21 jewels, straight-line lever escapement”
  • “monometallic balance adjusted to 5 positions”
  • “push button on the case band to individually adjust the second time zone”
