IWCThis IWC Aquatimer reference 816 AD is a vintage automatic diver's wristwatch featuring a turquoise-grey gradient dial with tritium indexes. Housed in a 40 x 42 mm steel case, it includes a screw-down back with an embossed submarine emblem and dual crowns: one for setting time and one for operating the internal rotating diving bezel.
The watch is powered by the IWC calibre 8541 automatic movement, which incorporates the proprietary Pellaton winding system. It is presented on a folded steel bracelet by Gay Frères. Distinguished by its gradient blue dial and compressor-style architecture, the watch was designed for depth-rated water resistance. The luminous material on the hands and indexes is noted for its lemon-colored patina, and the crowns feature the characteristic IWC fish logo, which the auction source associates with historical waterproof models; it does not verify present water resistance.
