This Sub Chrono International wristwatch is a rare vintage piece with a round, 45mm gold case and black rubber two-piece strap. The unidirectional rotating bezel comes with stick indexes and the black dial has 12-hour markers, a date indicator, and a seconds hand. The sapphire crystal is scratch-resistant and the watch is water-resistant up to 200m (20 ATM). The Swiss made quartz movement and screw-down crown make this watch a reliable choice for divers.
