The Rolex GMT-Master II reference 116718, produced between approximately 2005 and 2006, stands as a testament to Rolex's horological prowess and enduring legacy. This particular model holds a special place in the hearts of collectors, not just for its luxurious yellow gold construction, but also for its significance as a celebration of the 50th anniversary of the original GMT-Master, a watch synonymous with aviation and global travel. This article will delve deep into the intricacies of the 116718, exploring its design, history, and place within the broader context of the GMT-Master II line, while also touching upon related models like the popular 116710LN and its various iterations.
The 116718, bathed in the warm glow of 18-karat yellow gold, immediately commands attention. Unlike its stainless steel counterparts, this model exudes an undeniable opulence. The golden hue complements the iconic bi-directional rotating bezel, typically featuring a black Cerachrom insert with 24-hour graduations, perfectly suited for tracking a second time zone. This ceramic insert, a hallmark of modern Rolex GMT-Master IIs, offers superior scratch resistance compared to earlier aluminum bezels, ensuring the watch's pristine appearance endures the test of time.
The case, measuring a substantial 40mm in diameter, is perfectly proportioned for comfortable wear. Its robust construction, typical of Rolex's unwavering commitment to quality, ensures both durability and water resistance to a depth of 100 meters (330 feet). The screw-down crown and Triplock system further enhance its water resistance, protecting the intricate movement within.
The dial, usually black, provides excellent contrast against the golden case and bezel. The luminous hour markers and hands, ensuring legibility in low-light conditions, are a crucial element of the watch's functionality. The GMT hand, distinguished by its arrowhead design, allows for the simultaneous tracking of three different time zones: local time, home time, and a third time zone via the independently adjustable bezel. This sophisticated functionality is a defining characteristic of the GMT-Master II line, and the 116718 carries this legacy with pride.
The movement powering the 116718 is the caliber 3186, a self-winding mechanical movement entirely manufactured by Rolex. This movement is known for its precision, reliability, and power reserve of approximately 48 hours. The caliber 3186 incorporates a Parachrom hairspring, a Rolex-patented component made from a paramagnetic alloy, providing exceptional resistance to shocks and magnetic fields. This ensures the watch's accuracy remains unaffected by external influences. The meticulous finishing and attention to detail are hallmarks of Rolex's commitment to excellence, visible even through the sapphire crystal caseback (though this is not always the case with all versions of the 116718).
