Each Graham timepiece is created with special features and functions: Tourbillon; Split seconds or rattrapante chronograph; the combination of Flyback or retour en vol chronograph, GMT/second time zone and big date; column wheel or roue à colonnes (R.A.C.) chronograph; alarm with GMT/second time zone. This historic Britsh brand boasts of first rate Swiss movements that are exclusively engineered or adapted for it, creating remarkable timepieces made of top quality material that are precisely crafted from an engineer’s perspective. Known for their fairly large sizes, Graham watches are spectacular for the details they feature; from the functional helium escape valves for diving watches, to the hand-engraved representation of the Greenwich Royal Observatory, for which George Graham was the official watchmaker, on the caseback, to the use of sapphire crystals for a pristine and scratch free look, no detail is too minute to be left to chance. Every crevice of a Graham chronograph—be it a sportswatch or luxury item—has been given thoughtful consideration for the best functioning and most sophisticated product.
