I haven't seen one of these in a long time!
They are beautiful! The Les Complications collection was roughly from the late 90s-early 00s (don't remember the exact years) The watch was 43mm in diameter and ultra-thin.
The movement is Cal. 1701SQ. It was the last true Pocket Watch movement used by VC and had a 41 hour power reserve ( 21,600 vph, 20 jewels, 36.10 mm diameter, 1.90mm thick).
