A cosmic explosion in greys and blues, the Arnold & Son Nebula 41.5 Steel is a fully equipped powerhouse of a watch with an open-worked display. The symmetry of this timepiece is an integral part of its design, with every detail considered to achieve balance and harmony visually. Beyond its sleek and impressive display, this watch is also highly functional with its incredible 90 hour power reserve, only requiring hand-winding every three and a half days.

Ref. 1NEAS.U02A.S134D

Powering this stylish timepiece is the A&S5201 calibre which was conceived from the ground up to be a skeleton mechanism, allowing a clear view of the movement from every angle. From the front the skeleton dial gives an unobstructed view of the star-like pattern formed by its seven bridges radiating outwards. On the reverse, "Rayons de la Gloire finishing brings dimension to the main plate. A stainless steel bracelet keeps the Arnold & Son Nebula looking sharp on the wrist.
