Benrus Ultra Deep

SuperCompressor 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 SuperCompressor 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 is compressed, pushing on the gaskets and creating a tighter seal.

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. The SuperCompressor cases came in two sizes, 36mm (featured here) and 41mm.

This particular example is branded by the US based company Benrus, and features a classic 36mm ESPA case with dual crowns and an internal rotating dive bezel. The idea behind the design is that they’re less prone to accidental rotation that an external bezel. It is perhaps this feature that has become the most endearing feature of Super Compressors to collectors today. Practically, they worked out great for warm water divers, but anyone with gloved hands would have struggled.

This particular example is in excellent condition throughout, with crisp lume and "Cathedral" hands. Sporty yet comfortably sized, it conveniently houses an automatic Swiss movement.
