Rolex Oyster 4271

Part of the “Oyster Junior Sport” line, this manually-wound 1940s model is significant for its role in Rolex’s market-specific strategy, particularly in Canada. To offer an entry-level Oyster, Rolex used third-party Fontainemelon ebauches, which they finished and signed as Rolex Cal. 59. This reference highlights Rolex’s business acumen in adapting production to capture a wider market by providing the prestigious and durable Oyster case at a more accessible price point.
