A Girard-Perregaux R&D 01 Chronograph Monte Carlo 1983. Limited Edition of 250, released originally in 2009.
43mm (excluding crowns), and 14mm thick, it wears extremely comfortably on my 7.75" wrist. The case is designed by Luigi Macaluso, and features a reverse chronograph layout, with the chrono pushers and main crown on the left of the case, and the crown for rotating the internal bezel on the 4 o'clock point.
The watch features normal time functions, as well as a Day/Night indication at 3 o'clock, date at 6 o'clock, running seconds at 9 o'clock, chronograph hours at 12 o'clock. The seconds and minutes of the chronograph are represented by 2 separate center-attached hands - one in light blue, and the other in white with a light blue triangle tip.
The beautiful and thick Alligator strap is in black with contrast stitching, done (I believe) by Camille Fournet.
The watch in all of its glory, powered by the (hidden) cal. GP033C0:
