“In December they talked about SBS Seamasters but this was still unconfirmed rumors and something of a minor myth or urban legend amongst military watch collectors. Then they were all but unknown to the collector community, but now it seems to be veritably raining UKSF Seamasters.”
You have to take a step back to the original Rolex Submarine watch, the first to be defined by true military specifications and collaboration with stringent military grade benchmark:
“They were a different breed of beast entirely. Not only were they officially issued and thus more highly coveted by military watch collectors, but they were custom modified by Rolex at the factory from the drawing table forward with specially made hands, bezels, and special fixed bar lugs according to Royal Navy and Royal Marines stringent specifications, so much so that some like the 5517 were actually given a separate model reference that was never commercialized. So not only is there an issue pedigree, but the Milsubs were substantially differentiable from the regular production models in form and function.”
