Featuring the same calibre and finely detailed globe as the original GMT, the GMT Black is coated in ADLC (Amorphous Diamond-Like Carbon), resulting in a black finish. Not only is the ADLC coating aesthetically pleasing, it adds an additional layer of toughness as its surface hardness is greater than untreated titanium. Limited to 22 pieces.
