Graham dedicated a specific model to the Tourist Trophy, the legendary motorcycle racing event that every year takes place in the Isle of Man (this year was held from May 24 to June 6).
For the Chronofighter Oversize Superlight TT, Graham produced a lightweight black carbon nanotube composite case whose weight is just 51 grams. The total weight of the watch including the movement is under 100 grams.
The black ceramic bezel makes the watch very resistant to scratches. Water resistance is 100 metres.
The dial adopts a particular tachometer scale based on the TT circuit (37.73 miles / 60.7 km). The yellow indicator on the minutes counter at 6 o'clock is at 17 min (lap record time, 131.578 mph / 211.75 kmh established by John McGuinness in 2009).
Protected by the ultralight but strong case, the Calibre G1747 with Incabloc shock absorber beats at 28,800 vibration per hours and offers a power reserve of 48 hours. The movement is visible through the sapphire crystal case back decorated with the Isle of Man emblem with 3 legs, the "superlight" inscription and the serial number.
The Graham Chronofighter Oversize Superlight TT is a limited edition of 200 pieces and is completed by a black techno-fabric strap with red stitches and a black ceramic pin buckle. Retail price is Swiss Francs 7,500.
