3 GMT Watches For The Practical-Minded Jetsetter
Rolex GMT-Master II
Originally created for Pan Am pilots in the 1950s, the GMT-Master is synonymous with travel. The 2018 iteration is crafted in Oystersteel with a patented ceramic bezel in red (for day time) and blue (for night time). The date at ‘3’, enlarged via a Cyclops crystal, is synchronised with the local time.
Other solid features include the Triplock winding crown for unbeatable waterproofing (up to 100m), the Jubilee bracelet with five links, and the new calibre 3285 equipped with Parachrom hairspring that is 10 times more precise than a traditional hairspring in case of shocks.
Ball Watch Engineer Hydrocarbon AeroGMT II
Also created for a pilot, this time a crew of the Boeing 777, its most distinctive feature is the sapphire glass bezel. The original watch had a flat sapphire ring; this time around, the engineers have found a way to curve it to better match the domed sapphire crystal of the dial.
This watch actually displays three different time zones. Of course, there is the main dial with the usual 12-hour scale, its numerals lighting up in yellow and orange in the dark thanks to micro gas tubes. A second time zone is shown via a 24-hour scale on the dial, which is coated in blue Superluminova. You can read the third time zone on the red-and-black bezel, which is fitted with micro gas tubes that illuminate the 24-hour numerals in green under dim conditions.
Grand Seiko Blue Ceramic Hi-Beat GMT “Special” Limited Edition
Limited to 350 pieces, this beautiful Grand Seiko is crafted in a combination of lightweight but high intensity titanium and blue zirconia ceramic that is said to be seven times harder than stainless steel.
It is powered by the 9S86 calibre endowed with a fantastic precision rate of +4 to -2 seconds per day thanks to an oscillating weight crafted in titanium and tungsten, a combination that has a high resistance against shock.
