Following in the footsteps of its older but smaller brother, the Explorer II offers a tougher, more complicated answer to those who want to explore and ensure they have a reliable timepiece that won’t let them down. Typically you wouldn’t think a land explorer venturing across mountains would need to track two time zones but with modern technology increasing and travel abilities increasing, the expedition planned may take you across two separate time zones. Arguably an undervalued model within the Rolex range, those interested in this particular model, specifically the explorer, may want to consider Rolex’s oyster perpetual range.
