Rolex Oyster Perpetual 6100

The Rolex Oyster Perpetual ref. 6100, known colloquially as the ‘Ovetto,’ is a distinctive vintage model from the early 1950s, celebrated for its classic elegance and practical automatic functionality. This reference features a 34mm case made from stainless steel or gold, often paired with smooth or fluted bezels and a domed acrylic crystal, maintaining the waterproof integrity characteristic of the Oyster line. Powering the watch is the Rolex Caliber 645, a reliable automatic movement known for its bi-directional winding mechanism and approximately 42-hour power reserve. Dial options were classically styled, usually available in silver or champagne tones with applied baton or numeral markers, dauphine hands, and radium lume for readability. The watch has a lug-to-lug measurement of approximately 42mm and a lug width of 19mm, creating a balanced, timeless profile on the wrist. While not as prominently known as later Oyster Perpetuals, the ref. 6100 holds collector interest for its elegant proportions, historical significance, and embodiment of Rolex’s early post-war design evolution.
