An extremely fine and very rare 18k yellow gold manual-winding rectangle wristwatch ref.1593 retailed by Gübelin.
Ref.1593 - “The Hour Glass” due to its shape - is the first representative of a new wave of creativity in regard to shape watches which includes also “Marilyn Monroe” ref. 2442 and “Tour Eiffel” ref. 2441. It was in production from 1944 to 1967 in yellow gold, pink gold and platinum (no white gold examples known so far) for an estimated total output of about 1000 pieces. The elected case maker for this watch (as well as for reference 2441 and 2442) was Markowsky - casemaker number 8, in a key as for all Geneva-based makers - specialised in shape cases.
The present watch is distinguished not only by the superb condition of its case, but most notably for the Gübelin signature on the dial. It is interesting to note that another Gübelin-retailed 1593 is known, bearing a serial number three digits away from the present piece. An educated guess is that these watches were part of a batch made specifically for the Lucerne-based retailer.
