But, if you’re not a yacht racer, there’s plenty more functionality within this watch. The original Chronomaster from 1963 had the exact same broad arrow and dauphine hand set, with the same spearhead running seconds hand, and even the red paint on the minute markers denominating 10 minutes for use in yacht racing. As far as modern recreations of vintage watches go, this Nivada Grenchen effort is absolutely superb. The Chronomaster Aviator Sea Diver is by far Nivada Grenchen’s most recognisable watch to the average viewer, made especially familiar due to its classic looks. The water resistance is only rated at 100m, but with a screw-down crown you should feel safe taking this watch swimming as long as you’re careful not to hit the chronograph pushers. It is possible that you may accidentally move it slightly, but the benefit of having no clicks means that you will always be able to get perfect alignment anywhere on the bezel. The bi-directional non-latching bezel is thin enough to allow a lot of dial real-estate, and also has a nice, stiff rotating action. I say “deceptively” because of the presence that the watch carries, almost feeling like a much larger watch that just fits an average wrist better. The diameter is 38.3mm and the lug-to-lug length of 46.5mm makes it a deceptively versatile watch. Even with a thickness of 14.8mm, the profile of the case side offers a slender drape across the wrist with most of the bulk taken up by the screw-down caseback and domed sapphire crystal. It’s a refreshing twist on the all-brushed cases that can leave sports watches looking dull, with only the thin strips on the inner sides of the lugs being brushed. The lugs have a long, flowing curve to them that’s very typical of 1960s bicompax styles, yet the angle of the polished chamfer always seems to catch the surrounding light in a very appealing way. The caseĪlthough it looks fairly straight-forward in images, the case of the Chronomaster Aviator Sea Diver is much more characterful in the metal. The Nivada Grenchen Chronomaster Aviator Sea Diver Automatic takes one of their most legendary watches from the past and upgrades it with modern specifications.

Nivada Grenchen are one of those brands that make you wish you’d heard of them years before you first saw them due to their knack of delivering some of the most perfect executions of vintage reissues that can be found in the Swiss watch industry today.
