Collectors value this reference for its 40mm stainless steel case, which shares the same architecture as the Rolex 5513, and its Fleurier caliber 390 automatic movement. Early examples feature \"square\" or \"eagle wing\" crown guards and \"gilt\" chapter ring dials, while later iterations transitioned to \"pointed\" and eventually rounded crown guards with matte dials. As the first Tudor Submariner to feature a chronometer-style case, it represents a significant evolution in the brand's professional tool watch history. Current secondary market prices typically range from $10,000 to over $40,000 depending on the specific dial configuration and case condition. A notable variant is the 1959 \"Square Crown Guard\" model, which commands a significant premium due to its extremely limited production run.", "score": 199}]}
