Chopard L.U.C Perpetual T Grand Complication

The L.U.C Perpetual T is under the Chopard's Grand Complication family, right after the revered L.U.C 150 'All in One'.  The dial layout looks the same except this 2013 Perpetual T dial is hand-guilloche with sunray lines radiated out from the L.U. Chopard logo.

The hand-wound tourbillon and perpetual calender movement is COSC certified to guarantee good daily rate while the finishing abides by the Geneva Seal new standards.

 
L.U.C Perpetual T, is a combo of two big complications - a perpetual calender and a tourbillon.

 

Cased in 43mm diameter 18K rose gold case at a thickness of 14.90mm.  Water resistance is rated to 30m.

A very visible Big date at 12H.

Perpetual calender functions - days of the week and 24-hour indicator at 9H.  At 3H, the months and the leap year indicators.

The tourbillon does one full turn per minute, also acts as the small second.

Case is finished in dual polishing - gloss polishing at top facing while the side is brush-finished.

The above corrector at 8H is for day correction.

Dauphine hands coated with Super-Luminova for low light  time-reading.  The minute hand is at a good length for quick accurate readout
from the minute-track.

Clear second-track marking along the circumference of the tourbillon cage.

Note the finishing of the tourbillon bridge.  Have a few external angles which require a skilled polisher many hours to hand-finish.
