With Rolex fitted presentation box.
This Rolex reference 5512 "Explorer dial" was purchased by its current owner in 1962 from Kutchinsky Jewellers, Brompton Road, Knightsbridge.
The owner, who later became a member of a police specialist firearms unit, wore the watch during numerous operations including the Iranian Embassy Siege in London which ended on 5th May 1980.
The present Submariner is a particularly rare version of the reference 5512 model. The Explorer dial Submariners were believed to be produced in very small numbers during the late 1950's early 1960's.
Pointed crown guards can only be found in the first few years of production. Lovingly referred to as "cornino" by Italian watch enthusiasts, the ends of these crown guards are much thinner, almost tapering to a point, compared with the more rounded crown guards of later standard Rolex production
