Essay:  The  is a true rare oddity from Patek’s catalog that was exclusively made in stainless steel. Designed with a focus on water resistance, the ref. 1485’s two-part case, made by Taubert, utilizes an innovative system with three sliding sides that lock the case together. This design included an inner compartment with gaskets that were compressed against the metal sliders on the outer case. The patent for this novel case design was filed on August 25, 1938, under Swiss patent CH 207378 and published on October 31, 1939. As of now, only around 21 or so examples of the ref. 1485 have surfaced on the market. Measuring 27mm wide and roughly 35mm tall, the ref. 1485 was a large watch for its time with large circular lugs and an equally large easy-to-use winding crown. Only offered with a silver dial, the ref. 1485 is a completely monochromatic timepiece that broke from Patek’s conservative design language and dared to do something new and unusual.
