Vintage Omega Rectangular 'Tank' Automatic Watch

This is a vintage Omega men's wristwatch featuring a rectangular, tank-style case constructed of yellow gold-toned metal, likely 14k or 18k gold-filled or solid gold depending on the specific reference. The case dimensions appear to be approximately 30-38mm. It features a silvered or champagne-colored dial with applied gold-tone baton hour markers and matching alpha-style hands. Underneath the Omega logo and wordmark, the dial is inscribed with 'AUTOMATIC', indicating it houses a self-winding mechanical movement, likely a caliber from the 1950s or 1960s. The dial shows significant 'stardust' or 'tropical' patination, characterized by heavy spotting and oxidation across the surface, which is common in vintage pieces of this era. The acrylic crystal shows some light scuffing. The watch is fitted with a reddish-brown crocodile or alligator embossed leather strap. The crown appears original, featuring the Omega logo. The overall condition shows honest wear consistent with age, specifically regarding the dial degradation, while the case retains sharp lines despite micro-scratching. This style represents the elegant mid-century aesthetic favored by prominent watchmakers following the success of the Cartier Tank design.
