Rolex GMT-Master II “SARU” Sapphire/Ruby/Diamond Bezel 116748SARU BLACK OYSTER

The Rolex GMT-Master II Reference 116748SARU presents a distinctive interpretation of the classic traveler’s watch, featuring a bezel crafted from alternating sapphire and ruby segments with diamond-set numerals. This configuration creates a refined visual contrast against the black dial and 18k yellow gold case. The 40mm Oyster case maintains the model’s balanced proportions while providing 100 meters of water resistance through its screw-down crown and case back. Finishing includes both polished and brushed surfaces, with particular attention to the bracelet where center links are polished and outer links receive brushed treatment. The black dial features applied 18k yellow gold hour markers filled with Chromalight luminescent material, maintaining optimal legibility despite the decorative elements.

This timepiece is powered by the Caliber 3186, a self-winding mechanical movement developed and manufactured by Rolex. The movement includes a Parachrom hairspring for improved resistance to shocks and magnetic fields, along with a Paraflex shock absorption system. The GMT complication allows simultaneous tracking of three time zones through the combination of the traditional hour hand, the 24-hour hand, and the bidirectional rotating bezel with 24-hour markings. The movement achieves COSC chronometer certification and delivers approximately 48 hours of power reserve. Operational features include quick-set date functionality and independent adjustment of the local hour hand, making it practical for frequent travelers while maintaining the brand’s standards for precision and reliability.

The watch is offered in mint condition, showing only minimal signs of previous wear consistent with careful ownership. It includes its original Oyster bracelet with Easylink comfort extension system and is accompanied by its official Rolex warranty card and documentation. As a limited production variant with gem-set bezel configuration, the 116748SARU occupies a particular position within the GMT-Master II collection, appealing to collectors seeking both technical functionality and distinctive aesthetics. The combination of precious materials, functional complications, and Rolex’s manufacturing standards contributes to its standing in the secondary market, where well-documented examples in this condition typically maintain strong collector interest.
