IWC began producing diver’s watches a while after the other brands and released its Aquatimer in 1967.
The model 812 AD had two crowns, where one was used for the handset and the other for the internal timing bezel. The watch was fitted with IWC's in-house calibre 8541 that used the famous Pellaton winding system. The Ingenieur models were equipped with the same movement.
This is a wonderfully preserved example where the case is in fantastic original condition and has never been overpolished or damaged.
