Introductory Summary
The Rolex Submariner reference 6204 is the earliest production Submariner, manufactured from 1953 to 1954, and marks the true starting point of the Submariner lineage. As Rolex’s first purpose-built dive watch, it established the fundamental design and functional principles that would define the model for decades.

Reference Profile
The 6204 belongs to the very first generation of Submariners and features a compact 37mm stainless steel case with no crown guards. Rated to 100 metres, it incorporates a black bidirectional aluminium bezel, acrylic crystal, and a black dial, reflecting Rolex’s experimental yet highly focused approach during the earliest phase of professional dive-watch development.
Movement Overview
The watch is powered by the Rolex calibre A260, an early automatic movement used during Rolex’s transition into sports and professional watches. With an approximate 42-hour power reserve, the A260 is valued today primarily for its historical significance, representing Rolex’s early self-winding technology prior to the later 1000-series calibres.
Functions & Complications
The Rolex 6204 displays hours, minutes, and central seconds only, with no date complication, resulting in a clean and utilitarian dial layout. It features a bidirectional timing bezel for basic elapsed time measurement, a screw-down crown, water resistance rated to 100 metres, and was originally fitted with a riveted Oyster bracelet typical of early 1950s Rolex watches.
Buyer Considerations
This reference is highly sought after by advanced collectors due to its status as the first Submariner reference. Originality is paramount, with dial configuration, bezel insert, handset, and case condition having an outsized impact on value, while later service parts or polishing can significantly reduce collectability.
Comparisons & Aternatives
The 6204 is most often compared to the closely related 6205, which followed shortly after with minor refinements, and to later early references such as the 6536 and 6538 that improved depth ratings and movement robustness. Within the broader history of dive watches, it stands alongside the earliest Blancpain Fifty Fathoms as one of the foundational models of the genre.
