This watch is an astounding and incredibly rare variant of the reference 1675. Produced in 1963, this watch was manufactured only a few years after the launch of the reference. This beautiful lacquer dial features both an 'underline' and 'double Swiss' signature. Today, Rolex collectors and historians hypothesize that the underline and double Swiss signature denotes a transitional period, signifying Rolex's use of tritium on the dial instead of radium. Indeed, the serial number and production year supports this hypothesis.

Since 'double Swiss underline' watches were produced for such a short time, examples like this rarely appear on the market, making this watch very special. The numerals on this watch have furthermore turned an attractive and rather beautiful ivory colour, which consistently match the hands. The lacquer dial is intact, and all the gilt lettering has been preserved in excellent condition. The watch is furthermore fitted with a small tipped hand and pointed crown guards, which is correct for early examples.
