Wittnauer Super Compressor

Wittnauer Super Compressor

What does Wittnauer have in common with Jaeger-LeCoultre, Longines, Blancpain, Universal Geneve, and Zenith? They all sold the same damned watch.

Super Compressor diving watches are a category unto themselves, and the best Swiss brands sold versions of the distinctive dual crown watches that have been one of the most popular types of dive watches for years.

The Super Compressor name refers to the innovative case design, which utilizes a "compressor" system that’s designed to become more watertight the deeper that the watch went under water. As the atmospheric pressure increases along with depth, the case back in compressed, pushing on the gaskets and creating a tighter seal.

The compressor case wasn’t any better at preventing water intrusion than a screw-down crown (in fact, it was probably worse), but due to their good looks, compressor cases proved to be popular during the 1960s. Eager to get into the burgeoning dive watch market, many of the best Swiss brands turned to EPSA (Ervin Piquerez, S.A.), the leading manufacturer of compressor cases at the time, for cases to build their divers around.

It is perhaps the internal bezel that has become the most endearing feature of Super Compressors to collectors today, and the idea behind them is that they’re less prone to accidental rotation that an external bezel. They worked out great for warm water divers, but anyone with gloved hands would have been out of luck (but at least stylish!).

Each brand's variant riffs on the familiar formula of a 36mm EPSA case, dual crowns, and the characteristic internal rotating diving bezel in their own way. In the case of this Wittnauer, the dial features bold hour markers at 6:00, 9:00 and 12:00 (with the date at 3), large sword hands, and the case has thick, faceted lugs.
