A few years ago at SIHH, IWC released a slew of new models in its revamped IWC Aquatimer collection of luxury divers’ watches (Click here to check them out). For fans of vintage watches — and vintage IWC watches, specifically — we highlight here six important IWC Aquatimers from the brand’s history.
Milestone No. 1: First Aquatimer (1967)
In 1967, IWC reacted to the growing popularity of amateur scuba diving and launched its first divers’ watch. The first Aquatimer (Ref. 812AD) was water-resistant to 200 meters and became the foundation of a successful new watch family for the watch brand from Schaffhausen.
Milestone No. 2: Ocean 2000 (1982)
Working closely with designer Ferdinand A. Porsche, IWC began producing the Ocean 2000 sports divers’ watch (Ref. 3500) in 1982. For a time replacing the Aquatimer in the collection, it was the first series-built divers’ watch in titanium, with a tested water-resistance to 2,000 meters.
Milestone No. 3: Aquatimer GST Automatic 2000 (1998)
In 1998, IWC reinstated the traditional Aquatimer name and launched the Aquatimer GST Automatic 2000 (Ref. 3536), in a titanium case water-resistant to 2,000 meters, as part of a new line of sports watches.
Milestone No. 4: Aquatimer GST Deep One (1999)
In 1999, IWC unveiled the Aquatimer GST Deep One (Ref. 3527). Also in a titanium case, it was the first IWC divers’ watch to incorporate a mechanical depth gauge, with a flyback hand for the maximum depth, and an internal rotating bezel to display dive times.
Milestone No. 5: Aquatimer Split Minute Chronograph (2004)
In 2004, with the Aquatimer Split Minute Chronograph (Ref. 3723), IWC launched a divers’ watch equipped with a world-first function: a split-minute hand that operated separately from the chronograph and could be activated or deactivated underwater, to a depth of 120 meters.
Milestone No. 6: Aquatimer Deep Two (2009)
In 2009, the Aquatimer Deep Two (Ref. 3547) from IWC Schaffhausen succeeded the GST Deep One. It included a precise mechanical depth gauge that showed current dive depth as well as the depth attained during a dive, to a maximum of 50 meters.
