The present Rolex wristwatch is a stunning example of the reference 5508, the upgraded version of reference 6536/1, depth rated to 100 meters (330 ft), the case without crown guards. In production from 1957 until circa 1961, the dial correctly displays the signature Rolex and the words Oyster Perpetual and Submariner in gilt while the depth rating of 100m=330ft is white.
On closer inspection of this attractive timepiece, one will notice that the dial is turning a lighter black/brown due to aging and a sought-after 'spider' pattern has developed on the dial over the last 50+ years. Combined with a faded grey bezel, this watch emulates full character and charm that is only found on well-preserved Rolex sports watches from this era. Furthermore, this watch is offered with its original Rolex Guarantee and presentation box, an exceedingly rare occurrence for collectors.
