Rolex COMEX Submariner

About this reference

The Rolex Submariner reference 5514 was produced exclusively for the Compagnie Maritime d'Expertises (COMEX) between approximately 1972 and 1978. Unlike the standard reference 5513, the 5514 features a built-in helium escape valve on the left side of the stainless steel case, a technical requirement for saturation diving. It utilizes the caliber 1570 non-date movement. Collectors value this reference because it was never available for public retail, making it a purpose-built tool watch with a documented professional provenance. Most examples feature a COMEX-branded logo on the dial and a unique serial number engraved on the caseback. On the secondary market, these watches typically command prices in the low-to-mid six-figure range, depending on condition and service history. A notable production detail is that early versions were delivered with "Pre-Comex" dials, which lacked the company logo despite having the specialized case construction.
