Swiss luxury watch brand Graham presents Chronofighter Superlight Carbon Tourbillograph, a 100-piece limited edition high complication watch to mark the 10th anniversary of Graham’s very first Tourbillograph. This new timepiece houses the G1780 automatic column-wheel chronograph-tourbillon movement.
This timepiece has a 47 mm superlight carbon composite case. A carbon trigger, bezel, dial and buckle, as well as a tourbillon cage weighing just 0.485 g, contribute to the Chronofighter Superlight Carbon Tourbillograph being less than 100 g.
In performance terms, movement details such as Incabloc® shock absorbers, black low-friction coating on the column wheel, an oscillating mass with ceramic coating and anti-magnetism are signatures of staying power. The progressive integration of tourbillon tradition, steeped in history, into a reliably sporty watch is mirrored by the watch’s entire design language.
Two patented inventions were made in the process. First, the offset construction and the open cage of the Tourbillon allow other wheels of the movement to intersect with the Tourbillon’s orbital plane. This in turn allows a wider opening in the dial to see the device at work and integrates it completely into the movement. The inventors have named this design cintré.
The second is the Tourbillon which rotates between two characteristic bridges, designed for rigidity in a bent shape which is in the best tradition of English high precision timepieces of the 18th century. It makes the Tourbillon of the Chronofighter Superlight Carbon Tourbillograph more rugged and reliable than a Tourbillon volant or flying Tourbillon only mounted on one side.
Even the black rubber reset pusher has a patterned Clous de Paris and easy to grip surface. And golden elements on the dial remind the carbon to keep its feet on the ground.
