Partially verified

The Chopard L.U.C Chronometer Regulator, reference 16/8449, is a limited-edition stainless steel wristwatch produced in 2008 as part of a series of 250 pieces. This timepiece features an anthracite and silver regulator-style dial with applied white gold Arabic numerals, a subsidiary dial for hours at 3 o'clock, a 24-hour day/night second time-zone display at 9 o'clock, a seconds indicator at 6 o'clock, and a power-reserve sector at 12 o'clock. The watch is powered by the manual-wind Calibre 4RT, which features twin barrels providing an 8-day power reserve, 39 jewels, and a swan-neck micrometer regulator. The case is a two-body polished design with concave lugs and a pusher at 8 o'clock for adjusting the second time-zone. It is secured by a double deployant stainless steel clasp and is accompanied by original documentation, including the Certificate of Origin and Chronometer Certificate.

Object description

Case and Dial Design

The watch is housed in a two-body, polished stainless steel case featuring concave lugs and a transparent back secured by eight screws, revealing the movement. A push-button is integrated into the case band at the 8 o'clock position, specifically designed to advance the second time-zone hand in one-hour increments. The watch is worn on a strap with a stainless steel double deployant clasp.

The dial exhibits a complex regulator-type layout in anthracite and silver tones. Applied white gold radial Arabic numerals occupy the outer reserve. Individual subsidiary rings display the hours at 3 o'clock, a 24-hour second time-zone with day and night indication at 9 o'clock, and the seconds at 6 o'clock. An 8-day power-reserve sector is positioned at 12 o'clock. The hands are crafted from blued steel and incorporate luminous material for visibility.

Evidence for this section
  • “Two-body, polished, concave lugs, button on the band at 8 for advancing the second time- zone hand in one-hour increments”
  • “Anthracite and silver with applied radial white gold Arabic numerals on an outer reserve”
  • “Luminous blued steel dauphine hands”

Movement and Performance

Internally, the timepiece is driven by the Calibre 4RT, a rhodium-plated movement finished with fausses cotes decoration. The construction centers on twin barrels to maintain an 8-day power reserve, supported by 39 jewels. The escapement is a straight-line lever type equipped with a shock absorber and a self-compensating Breguet balance-spring.

Precision is maintained through a swan-neck micrometer regulator. The monometallic balance is adjusted to perform under heat, cold, and isochronism, specifically across five positions to ensure accuracy as a chronometer.

Evidence for this section
  • “Cal. 4RT, rhodium plated, fausses cotes decoration, twin barrels, 39 jewels, straight-line lever escapement”
  • “swan-neck micrometer regulator”
  • “Overhaul recommended, at buyer's expense”
