Nebula 41.5 steel

  • 41.5 mm case
  • Black ‘ballistic’ rubber strap
  • 30 meters water resistance
  • Stainless steel pin buckle


Arranged in a star around the edge of the calibre, the openworked, chamfered and satin-finished bridges create the impression of a watchmaking explosion, as well as a sense of rhythm and control. Positioned at regular intervals, these bridges are identical in shape but different in size and reflect the aesthetic heritage of John Arnold’s chronometers. They also illustrate Arnold & Son’s ‘Manufacture’ expertise.
