The Explorer II was developed in the 1970s for cave explorers. Featuring a fixed 24-hour bezel and coordinating red arrow GMT hand on the dial to allow cavers to distinguish between day and night hours.

For most wearers, the GMT complication is best served to track a second time zone.

The 2010 version of the Explorer II features the 3186 version of the movement. 

This watch is in excellent all round condition. Case is think and sharp, how it should be.

Movement has been serviced by my watchmaker and is running to spec, as well as pressure tested.

Watch comes with 2010 card, inner and outer boxes, red tag, card holder and booklets.
