Pre-Loved Rolex Explorer II
The 24-hour explorer's tool watch, built for the dark

Why the Explorer II is iconic
Launched in 1971, the Explorer II was designed so speleologists could distinguish day from night underground using its 24-hour hand and fixed bezel. The 2011 reference 216570 revived the orange hand of the original 1655 'Steve McQueen', cementing its cult following.
What to pay pre-owned
Pre-owned Explorer IIs in the UK typically sit around £6,950, with the earlier 40mm 16570 often below that and the current 42mm 226570 above it. Full box and papers, a documented service history, unpolished cases and the sought-after white 'Polar' dial all push prices toward and beyond the upper end.
Sizes & variants
Buyers seek the 40mm references 1655, 16550 and 16570, and the modern 42mm 216570 and 226570, choosing between black and white 'Polar' dials with black or orange 24-hour hands.
How to authenticate
- 1.Cross-check the model reference and serial number against Rolex records and confirm they are cleanly and correctly engraved for the era of the watch.
- 2.Have the movement inspected by a watchmaker for a genuine Rolex calibre with correct finishing, and weigh the watch, as the solid Oyster case and bracelet should feel substantial rather than light.
- 3.Scrutinise dial printing under magnification for crisp, even text, verify the box and papers match the watch, and buy only from sellers offering a written authentication guarantee.

Buying a pre-owned Rolex Explorer II — FAQs
What is the 24-hour hand for?
It points to the fixed 24-hour bezel so you can tell whether it is day or night, which is useful underground, at the poles or when tracking a second time zone.
Is the Explorer II waterproof?
Yes, it is a proper Oyster-case tool watch rated to 100 metres, though on a pre-owned example the seals should be checked and serviced if you plan to get it wet.
Black dial or white 'Polar' dial?
Both are original Rolex options; the white Polar dial is more distinctive and often commands a small premium, while the black dial reads as more discreet.
