Reference 530 was first launched in 1937 and remains one of the rarest chronograph models manufactured by the firm. Even though it takes design cues from its sister model, reference 130, the case size of reference 530 remains substantial even to today’s standards with a whopping 36.5mm. diameter which wears even larger due to its relatively thin bezel. It was available either as a chronograph or time-only model.

The present watch is cased in pink gold, which is much rarer than its yellow gold sibling. Research shows that we only know 16 examples of reference 530s cased in this precious metal, with an approximate total production number of 30 pieces, making the present watch an exceedingly rare specimen.

Showcasing wide, thick lugs and a hallmark beneath the lug, this chronograph wristwatch has been preserved in excellent condition, particularly when one considers the age of the timepiece.

Furthermore, the beautiful dial is also preserved in excellent condition with barely any signs of aging. It displays a "short" signature which is correct. One would expect a watch, fitted with a snap-on case back to be exposed to the elements, and thus tarnished and spotted heavily. However, this dial is crisp despite its age, and complete with raised hard enamel graphics. Furthermore, it was previously serviced at the Patek Philippe factory and still retains its factory servicing tag.
