The fifth one, again, can be difficult. I love the split-minute Aquatimer, and believe it is “under-appreciated” today by the market. But then I would have all “historical” models, and some of the more modern ones should not be ignored. Given so many great contemporary representatives, I like those that serve as “basic representatives, the 2017 Aquatimer Automatic 2000 and the Sharks edition chronograph. The Sharks model is powered by the in-house automatic caliber 89365, an integrated fly-back chronograph with column-wheel and vertical clutch.
Given that my first three diving watches are “time-only” models, and given my partiality to chronographs, the Sharks model, IW379506, is my fifth choice. This is especially the case because I believe that movements are the essence of fine mechanical watches, and the calibre 89365 is an especially fine movement, one of the best chronograph movements ever produced in Switzerland.
In actuality, I think it would be better to choose ten diving watches from IWC. But I can’t do that – having already chosen five Ingenieur, Portuguiesers and Pilot’s watches. There are so many watches, and so little time to dive even deeper.
