Rolex. A rare stainless steel automatic dual time wristwatch with sweep centre seconds, date, underline black gloss dial, pointed crown guards and bracelet

With Rolex original presentation box and outer packaging.

The present watch is a fine example of a Rolex reference 1675 featuring the early pointed crown guards and the presence of the original "small triangle" GMT-hand. The pointed crown guards are found on early examples, which were soon abandoned for classic round ones. The present watch also features the much sought-after "underline dial", characterized by a small silvered line underneath the gilt designation "Officially Certified". The gilt writing and minute markings are not printed on the black gloss dial, but underneath and shine through in negative relief. However, the silvered underline is superimposed and printed onto the black background. Underline dials were used by Rolex on watch dials for a short period of time to indicate the use of tritium as a luminous compound, which is less harmful than radium.
