Graham Watch Chronofighter Oversize Superlight Carbon Lightning 2CCCK.B41A.K92K. Graham was among the very first watch brands in proposing a full carbon watch, of less than 100 grams weight ultimately. To continue the 10 years of recurring success with the Superlight Carbon Chronofighter, our team is proud in presenting a new Carbon base material to add on the existing Superlight line: The Lightweight Translucent Matrix LTM Carbon. Developed with one of our historical partners in Switzerland, the Superlight LTM Carbon breaks new standard with a red translucent matrix revealing Carbon folds floating into. As revolutionary as it could be, and as lightly brilliant as will be your next Graham Chronofighter Superlight watch.
