Jaeger-LeCoultreThis Jaeger-LeCoultre wristwatch, identified as the Master Control 1000 Hours Géographique, reference 142.3.92, dates to the late 1990s. The watch is constructed in 18K white gold and features a three-body polished case with concave lugs and a transparent case back secured by four screws.
The two-tone silver dial includes applied white gold dart indexes and white gold dauphine hands. It functions as a world time piece with center seconds, an aperture for a bi-directional rotating city disk, and a secondary crown positioned at 10 o'clock to adjust time zones. The movement is a self-winding Caliber 929/3, rhodium-plated with fausses côtes decoration, 38 jewels, and a 22K gold rotor segment. Additional complications include a date indicator, a 40-hour power reserve display, and a day/night indicator.

Design
- Case and Dial
- The watch is housed in a three-body, solid, polished 18K white gold case measuring 38 mm in diameter and 12 mm in thickness. It features concave lugs and a transparent case back secured by four screws, allowing visibility of the internal mechanics. A secondary crown is located at the 10 o'clock position, specifically designed to control the city selection for the world time function. The dial is rendered in a two-tone silver finish, incorporating applied white gold dart indexes and dauphine-style hands. Sub-dials displaying guilloché patterns provide readings for the second time zone, the date, and the up-and-down power reserve indication. An aperture is positioned to display the bi-directional rotating disk containing the names of major world cities.

- Movement and Escapement
- The timepiece is powered by the self-winding Caliber 929/3, which is rhodium-plated and finished with fausses côtes decoration. The movement includes 38 jewels, a straight-line lever escapement, and a monometallic balance that is adjusted to 6 positions. It is equipped with a shock-absorber system, a self-compensating flat balance-spring, and a micrometer regulator for precise adjustments. The winding system utilizes a 22K gold rotor segment to improve efficiency. The movement, along with the case and dial, is signed by the manufacturer, reflecting the construction standards of the Master Control series during this period.
