Object description

Case and Dial

The watch is constructed in steel with a case diameter of 42 mm. The white-colored dial is configured with luminescent applied hour markers and matching luminescent hands, intended to provide readability. The dial layout includes three distinct sub-dials dedicated to measuring chronograph seconds, hours, and minutes, alongside an auxiliary window for the date calendar located at the 4 o'clock position.

A bidirectional rotating bezel encircles the crystal, which is composed of sapphire. The external profile of the case includes a fluted crown at the 3 o'clock position, which is protected by double gaskets to support water resistance, and a double-pusher arrangement for the chronograph functions.

Evidence for this section
  • “In steel.”
  • “White colored dial with luminescent applied hour markers and Tag Heuer's signature luminescent hands”
  • “Bidirectional rotating bezel.”
  • “Sapphire crystal.”

Movement and Functionality

The watch operates using a quartz movement. The "1/10" designation refers to the chronograph's capacity to measure time intervals with an accuracy of one-tenth of a second. This measurement is achieved via a dedicated 1/10th chronograph hand, which works in conjunction with a central chronograph hand to track elapsed time.

However, the documentation notes that collector's watches often have complex mechanisms, and the purchaser assumes responsibility for any future adjustments, general services, or repairs required.

Evidence for this section
  • “Quartz movement.”
  • “The "1/10" designation refers to the ability of its chronograph to measure time intervals with an accuracy of one tenth of a second.”
  • “In the description of the watches when it is noted "in running condition" it means that the watch is running.”
  • “purchaser is responsible for any general service, overhaul, battery change, adjustment or repair that may be necessary.”
