ChopardThis gentleman's wristwatch is a limited edition piece from Chopard’s L.U.C collection, numbered 1 of 25 examples. The watch is housed in a palladium (0.950) case measuring approximately 40.5 mm in diameter, featuring a skeletonized dial with applied blue Roman numerals and indexes.
Complications include a one-minute tourbillon regulator and an 8-day power reserve indicator positioned at 3 o'clock. The timepiece is powered by the manual-winding L.U.C. caliber 4TT 3N, which utilizes "Quattro technology"—a configuration based on two sets of two stacked barrels. The movement features an 18K gold main-plate and bridges, and is adjusted to heat, cold, isochronism, and 5 positions. It is certified by the C.O.S.C. and carries the Geneva Quality Hall Mark.
The watch is worn on a brown crocodile leather strap with a platinum buckle and includes a sapphire-crystal case-back secured by eight screws.

Design
- Case and Dial
- The timepiece features a tonneau-shaped case crafted from 0.950 palladium. The case is fitted with a sapphire-crystal exhibition back, which is secured to the case body using eight screws. The watch measures approximately 40.5 mm in diameter. The dial is partially skeletonized, displaying components of the movement beneath. It is set with blue applied Roman numerals and indices. The visual layout incorporates two complications: a one-minute tourbillon regulator positioned at the 6 o'clock mark and a power reserve indicator located at 3 o'clock, which displays the remaining energy of the manual-winding movement.
- Visible features
- • Skeletonized dial exposing parts of the movement. • Visible one-minute tourbillon carriage at the bottom of the dial. • Power reserve indicator graduated from 0 to 8 days. • Case back secured by eight visible screws.
- Provenance and Documentation
- This example is one of 25 pieces produced in this limited edition series. Records indicate that the watch was originally sold on January 11, 2008.
- Movement and Technical Specifications
- The watch is powered by the L.U.C. 4TT 3N caliber, a manual-winding movement. A distinguishing technical feature is the "Quattro technology," which employs two sets of two stacked mainspring barrels to achieve an extended power reserve. The main-plate and bridges are constructed from 18K gold. The caliber is adjusted to heat, cold, isochronism, and 5 positions. It carries the Poinçon de Genève (Geneva Quality Hall Mark) and is a certified C.O.S.C. chronometer, operating at a frequency of 28,800 vibrations per hour.
