2.0322 EDOX ‘Hydrostar’ Compressor, Steel, Swiss 1966

£170.00 (incl. VAT)

Super smart and dressy Edox Super-Compressor. For a 60+ year old watch, the stainless steel case and highly reflective silver sunburst dial are in remarkably good nick! Features the ingenious Super-Compressor case, which takes advantage of the water pressure to form a tight seal within. Features mirror polish Dauphine style hands and applied indices, with brightly glowing lume. If you turn this watch slowly and if the light catches it just right, you can see where the retailer, Davenport Jewellers, has tried to remove the original Edox inscription on the caseback and replace with their own!

Key Features

This Edox is super smart and dressy, and delightfully simple in design. The condition of the steel and reflection of the silver sunburst dial and mirror polish hands and indices almost give the effect of it being factory fresh. There are some very minor scratches on the dial, but beyond that this is in remarkably condition for a watch from the 1960s. The Dauphine hands have brightly glowing lume and point very clearly to the applied indices. The hallmark inside the case is marked ’11-66′, denoting a November 1966 production date.

These compressors make excellent dress watches as they are slightly larger than their similar-period dress watches, and also because they are very well built with EPSA solid steel cases. However, the EPSA cases are not just for show. Developed and then patented in 1956 by watch case manufacturer Ervin Piquerez S.A. ( hence the name: EPSA), the “Super-Compressor” design takes advantage of the water pressure the case is exposed to at depth to press the case back against the o-ring seal. More depth equals more water pressure equals greater seal, and dual crown Super-Compressor watches typically have a depth rating of 600 ft. This same concept was employed by Omega in the Naiad crowns used on Seamaster 300 watches in the 60’s. Well regarded as being very high quality and watertight, EPSA manufactured the S-C cases in a variety of styles from the late 50’s until bankruptcy closed the business in the mid 1970’s. The fact that so many survive today is a testament to their quality.

About EDOX

Montres Edox et Vista SA (EDOX) is a reputable Swiss watchmakers, operating under the  Era Watch Company, with 130 years of quality watchmaking under their belt. The company was founded by watchmaker Christian Ruefli-Flury in Biel/Bienne in 1884, and they have successfully remained in continuous production since their foundation. Ruefli-Flury used the ancient Greek word Edox the trademark for the company, designing the “1900” hourglass as a visual symbol for the brand. Robert Kaufman-Hug took over the company when Ruefli-Flury died in 1921, leading the company’s transition from pocket watches to become the first wristwatch-exclusive watchmaker.

By 1955, the company employed 500 people and moved to a new factory. The Delfin line of watches launched in 1961, with industry-first double casebacks for high standards of shock protection, water resistance, and ruggedness. In 1965, Victor Flury-Liechti took over the company from his uncle, and invested in new manufacturing technologies. This led to the 1970 Geoscope timepiece, the first watch covering all time zones.

With the rise of Japanese watches and the Quartz Crisis in the 1970s, the company became an affiliate of the General Watch Company, a sub-holding company of ASUAG. However, at the end of the downturn in the Swiss watch industry in 1983, Edox regained independence when the company was sold to Victor Strambini Montres Vista SA and moved to Les Genevez, Jura Mountains. It has since remained a family-owned company.
