Double Impulse Chronometer | White Gold curved thanks to its blue subsidiaryThis is an example of a Charles Frodsham Double Impulse Chronometer* with a white gold case and a white ceramic dial with Roman numerals and marine chronometer style hands. The watch features the first instance of the miniaturisation of George Daniel's twin impulse escapement to fit into a wristwatch. The workshop produces no more than 12 examples of the Double Impulse Chronometer every year, with almost all components created and finished in house.
