1969 IWC Schaffhausen Aquatimer Ref.816

14-days Inspection Period / 1-year Warranty


Delivery: ca.10 days

Rare and understated icon of the late 60s by IWC Schaffhausen. The Auqatimer Ref.816 was an updated revision of the original Ref.812 offering all-new cushion-shaped case and dial designs, though, retaining the original caliber 8541 and then rather unique rotating inner-bezel. The Aquatimer's updated design was another attempt of Swiss watchmaking industry to fight the avalanche of quartz crisis and was in production just for a few years. Rare, pronounced, and offering much of the early 70s spirit.

Full service in July 2018. Technical warranty: 1 year.
