Rolex Explorer Ref. 6610 “Red Depth” with a 300k serial dating it to the 60s, one of the most desirable early Explorers ever produced.

The glossy gilt dial is exceptionally well-preserved with an even, attractive patina throughout the luminous markers and handset.

The automatic movement is running smoothly.

Comes with its original papers and Rolex pamphlet.

On its original Oyster bracelet with matching numbers, original 58 end links, and original clasp. It fits a size 6.5 wrist.

A cornerstone of vintage Rolex collecting.
