This is a classic JLC watch on an alligator strap with 18k RG deployant folding buckle. It features an automatic wind caliber with a power reserve indicator, a date and a world time-zone with a Day/Night indicator all on the lovely silvered dial. The 38mm case has an officer's style 18K RG hinged case back, that conceals under a sapphire crystal, the self-winding JLC caliber.
Ref# 142.2.92
Mint condition.
Serviced in March 2015, unworn since, it comes on a new non-JLC alligator strap with all original papers and box.
