GMT-Master II · Spotting fakes
The two-colour bezel and the independent 24-hour hand are where GMT counterfeits stumble.
A genuine Cerachrom GMT bezel has razor-sharp, even colour separation — the Pepsi's red-to-blue or the Batman's blue-to-black line should be clean, with crisp PVD-filled numerals. Fakes often show muddy colour transitions, uneven tone, or fuzzy markings. On vintage, the aluminium insert's font and fading should match the reference's era.
The GMT-Master II's defining function is the independently adjustable local hour hand. On a genuine modern watch you can jump the hour hand in one-hour steps while the 24-hour hand and minutes stay put. A 24-hour hand that won't operate correctly, or an hour hand that won't jump, is a strong fake signal.
Check the date sits centred and is magnified about 2.5x under the Cyclops, the rehaut engraving is sharp with a matching serial, and — on Jubilee or Oyster bracelets — the clasp codes and finishing are correct for the reference and year.
As with all modern Rolexes, super-clones exist. The movement and the precise operation of the GMT function are where they fall short — have a qualified watchmaker confirm anything sold below market.
