The Rolex GMT-Master II reference 16710, powered by the Caliber 3185 movement, underwent a complete professional service. The process began with a full disassembly of the movement, during which every component was inspected, cleaned, and re-lubricated with high-grade synthetic lubricants. Particular attention was given to the special mechanism that controls the independent GMT function, allowing the local hour hand to be adjusted separately from the 24-hour hand—an innovation that makes the 16710 and 3185 unique. This part was disassembled and lubricated. After reassembly, the movement was regulated and tested in multiple positions, confirming that the watch not only kept excellent time but also performed its signature dual-time function smoothly. The original Rolex bracelet was worn out, and was replaced with a quality Forstner stainless steel bracelet, a maker of quality bracelets for high end watches such as Rolex. Unlike cheap replica bracelets, these are well manufactured and fit perfectly, and do not infringe on the Rolex trademark. Also the bezel was and crystal was removed and cleaned in an ultrasonic cleaner, removing years of thick debris that prevent the rotation of the bezel.

Rolex 16710 with 3185 movement background
The Rolex GMT-Master II reference 16710, introduced in 1989, included a unique 24 time complication for the convenience of world travelers. Designed as the successor to the GMT-Master 16750, it featured a slimmer case profile and was powered by the newly developed Caliber 3185 movement. This automatic chronometer-grade calibre introduced a significant advancement: the ability to adjust the local hour hand independently of the 24-hour GMT hand. Produced until 2007, the 16710 remains a highly collectible piece.
