Jaeger-LeCoultre Reverso Gran'Sport Chronograph Wristwatch

Partially verified

This Jaeger-LeCoultre Reverso Gran'Sport is a manual-winding chronograph wristwatch housed in an 18K yellow gold case measuring 23mm in width. The timepiece features the signature swivelling Reverso case mechanism, allowing the wearer to transition between two distinct silvered dials. The primary dial displays standard time, a date aperture at the 6 o'clock position, and an Arrêt/Marche indicator to monitor the chronograph status. The reverse side features a chronograph display, incorporating a 60-second counter above a 30-minute retrograde register. The watch is powered by the Jaeger-LeCoultre Calibre 859 movement. It is fitted with an original rubber strap secured by an 18K yellow gold deployant clasp. The design incorporates distinctive gadrooning on the case extremities, consistent with the Gran'Sport series' aesthetic language, and utilizes luminous leaf-style hands on both dial faces against a guilloché grid pattern.

Object description

Case and Mechanism

The watch is housed in an 18K yellow gold case measuring 23mm. The case design utilizes the Reverso collection’s reversible mechanism, which allows the main housing to slide and rotate within its outer carrier. The exterior of the case is decorated with gadrooning, a series of rounded parallel lines that decorate the top and bottom sections of the lug area.

The watch is attached to an original rubber strap, which is connected to the case by fixed gold segments. The strap is fastened using an 18K yellow gold deployant clasp, maintaining the gold theme of the case. The rotating frame is designed to provide access to both sides of the watch head.

Evidence for this section
  • “18K yellow gold case is distinguished by signature gadrooning”
  • “Its ingenious reversible design reveals the chronograph dial with a simple flip-and-slide of the case”
  • “Complete with its original rubber strap and yellow gold deployant clasp”

Dials and Complications

The timepiece features two distinct silvered dials, both finished with a guilloché grid pattern and Arabic numerals. The primary dial serves as the time-telling face, incorporating luminous leaf hands, a date window at the 6 o'clock position, and an Arrêt/Marche indicator. This indicator serves to inform the user whether the chronograph function is engaged or disengaged.

The reverse side of the case houses the dedicated chronograph display. This dial features a central 60-second hand and a 30-minute register positioned below, which functions as a retrograde indicator for tracking elapsed time. The use of the guilloché grid and luminous leaf-style hands is consistent across both faces of the watch.

Evidence for this section
  • “primary dial is distinguished by a date window at 6 o’clock and an Arrêt/Marche indicator showing whether the chronograph is running or stopped”
  • “reverse chronograph dial displays 60 seconds above a 30-minute register”
  • “Both silvered dials feature an elegant guilloché grid pattern, Arabic numerals and luminous leaf hands”

Movement and Origin

The watch is powered by a manual-winding movement identified as the Jaeger-LeCoultre Calibre 859. The manufacturer, Jaeger-LeCoultre, is headquartered in the Vallée de Joux, Switzerland, where it has operated since its founding in 1833.

The source identifies the maison for its technical focus on horological innovations and the development of high-grade movements, such as the calibre used in this specific model. The movement enables the complex interplay between the primary time display and the chronograph functions located on the secondary dial face.

Evidence for this section
  • “powered by its high-grade manual-winding Calibre 859 movement”
