Reference 116718 places the GMT-Master II in a 40mm Oyster case crafted entirely from 18k yellow gold, paired with a matching Oyster bracelet featuring flat three-piece links and a folding Oysterlock safety clasp. The bidirectional rotatable 24-hour graduated bezel carries a black Cerachrom ceramic insert, purpose-built for reading a second time zone at a glance.
Behind the scratch-resistant sapphire crystal — complete with a Cyclops lens over the date — the black dial presents luminous hour markers for clear legibility in low light. A solid case back encloses the Calibre 3186, a self-winding perpetual mechanical movement with GMT function, approximately 50 hours of power reserve, and water resistance to 100 metres / 330 feet.
This example is offered in pre-owned mint condition and arrives as a full set: original Rolex box, papers dated 2006, Rolex service card, red Rolex tag, and bezel protector. A 2-year warranty is provided by Luxury Watches USA.
