During the final production of these discontinued Explorer II's, they were discreetly upgraded with Rolex's latest generation dual-time movement; the self-winding 3186 calibre. This Z-serial 40mm reference 16570 would have been one of the very first RRR pre-rehauts to benefit from this upgrade.

Discontinued in 2011 and kept in outstanding condition since, this polar dial Explorer with 24hr fixed steel bezel, offers two separate time zone display simultaneously. Powered by Rolex's respected 3186 dual-time calibre, and waterproof to 100m. UK retailed by the Goldsmiths group in October 2009, and presented with its Rolex box, accessories and Rolex international warranty card, under our two-year warranty.
