Rolex Oyster Perpetual 6103 Description

The Rolex Oyster Perpetual ref. 6103 is a lesser-seen vintage model from the early 1950s that was designed with both elegance and rugged utility in mind. Featuring a 34mm stainless steel case, the 6103 is most recognized for its smooth or engine-turned bezel and domed acrylic crystal. The reference is powered by the Rolex Caliber 645, a bi-directional automatic movement offering around 42 hours of power reserve, notable for its early reliability and ease of service. Dials were typically minimalist in style, often presented in silver or champagne tones with applied hour markers, dauphine hands, and luminous elements using radium. The lug-to-lug measurement is approximately 42mm, and the lug width is 19mm, giving it classic proportions for mid-century wristwatches. Although not produced in high quantities, the 6103 stands out among early Oyster Perpetuals for its clean design and durable construction. It offers collectors a window into Rolex’s evolution toward dependable, stylish automatic wristwatches in the post-war era.
