Rolex Explorer II 1655 MK2 Frog Foot Dial Albino

The Rolex Explorer II reference 1655 occupies a unique and revered place in the world of vintage Rolex collecting.

Introduced in 1971, it was purpose-built for professional explorers—specifically spelunkers—featuring a fixed 24-hour bezel and a striking, highly legible dial designed to distinguish day from night deep underground.

While many of Rolex’s sport models quickly evolved into status symbols, the 1655 remained quietly utilitarian for much of its life. It was a true tool watch, built for function over flair—a quality that today makes it one of the most desirable and characterful pieces in the brand’s vintage lineup.

Presented here is an early example: a Mark II “Frog Foot” dial, named for the distinctive coronet whose shape resembles a frog’s footprint.

The case and 24-hour bezel are in excellent condition and are paired with an Oyster bracelet, reference 78360, fitted with 580 end links and a clasp stamped “J1.”

The dial has developed a beautiful creamy-yellow patina on the hour markers and hands. The 24-hour hand has aged to a warm yellow tone, perfectly matching the lume across the dial—an honest and appealing vintage look.

This fine Explorer II has been fully serviced by our watchmaker and is ready to accompany its next owner for years to come.

Among matte-dial vintage Rolex sports models, the 1655 remains one of the coolest—and arguably most under appreciated. This example ticks all the right boxes: a vibrant faded-orange hand, a nice cased bezel plus a warm, even yellow patina throughout.
