Rolex Explorer 6610, Steel

The reference 6610 is something special. The predecessor to the 1016, only a handful were made, in comparison to the Explorer’s longer-running production reference. This particular case dates to 1957/58 (serial 268 XXX); a very early example of a rare watch.

The Rolex Explorer was first introduced in 1953. Beginning as a prototype designed specifically for professional use. Typically thought of as the most rugged of the oyster family, the Rolex Explorer has always been closely-associated with the rigors of international adventure and exploration. Famously tested during the Himalayan expeditions, there aren’t many mechanical timepieces more deserving of the reputation.

The case of this Rolex is in excellent condition. The brushing on top of the lugs is consistent, while the spring-bar spaces show little sign of elongation. The flat bezel is sharp and gives the watch an appropriate utilitarian feel.

Inside the watch, it houses Rolex’s famous ‘Officially Certified Chronometer’ grade 1030 movement. Noticeably different from today’s; the rotor features two hollowed prongs, along with the engraving ‘ROLEX PERPETUAL’ and ‘PATENTED’ underneath.

As with many great watches, there are celebrated characteristics that make it special. The 3-6-9 dial configuration is beloved by collectors for its distinguishable style and functional purpose.

This Rolex Explorer 6610 comes on a brown suede strap and generic steel, tang Rolex buckle.

Viewings can be arranged in Central London by appointment.
