Lot Essay

This model of Submariner was specially developed by Rolex for Compagnie Maritime d'Expertise, a professional diving operation for the oil industry. The gas escape valve was designed to release excessive helium pressure from the case during the diver's decompression periods.

A similar example of this model, reference 5513 made for Comex, is illustrated in Rolex Wristwatches by James M. Dowling & Jeffrey P. Hess, p. 267; and in Vintage Rolex Sports Models by Martin Skeet & Nick Urul, p. 52.
