Launched in 1967 as IWC’s first dive watch, the Aquatimer has become a legendary example of an iconic dive watch. While it is undoubtedly a diver, the Aquatimer retains IWC’s refined dressy demeanor in part thanks to its sophisticated bezel system. While external bezels are typically associated with tool watches and dive watches, the Aquatimer uses an internally rotating bezel that is operated by the crown at 2 o’clock, which is mirrored by the crown at 4 o’clock to create a distinct and symmetrical design. Combined with its clear and legible dial layout, stick hands and hour markers, the Aquatimer’s classic round case and angular lugs create a wonderfully familiar presence on the wrist that will comfortably fit most wearers. Powered by an automatic movement and packed with 200m of water resistance, the Aquatimer ref. 812 was an incredibly capable watch when it first came out, and is certainly still up to the task of taking on the daily battles of life on the wrist of a vintage watch enthusiast.

Watch is in excellent condition. Dial is free of blemishes. Caseback engravings are light but visible. Bracelet is aftermarket, made by Kreisler.

An icon within the dive watch niche, the Aquatimer has gone on to become one of IWC's most brand-defining tool watches, along with their Big Pilot and Ingenieur.
