HMS1

Ref. 1LCAS.S02A.C111S
With its understated simplicity, the HMS1 line is a modern take on Arnold & Son's traditionally elegant design combined with superior craftsmanship. Housed in a classically styled 40 mm case with see-through back, the hand-wound A&S1001 calibre is manufactured in-house and decorated with either straight or radiating (rayonnantes) Côtes de Genève guilloche. The movement is 2.7 mm in thickness with twin barrels generate a minimum power reserve of 90 hours and a more constant force, hence greater accuracy the whole time the movement is running.

Blued screws in the rhodium-plated movement, mirror-polished screws in the NAC grey version, and specific decorations for each version testify to the attention to detail. The HMS1 collection comes in a range of dial colours and with various finishes depending on the model, as well as a choice of cases in 18-carat white gold, 18-carat rose gold or stainless steel. It is also available with an exquisite diamond-set bezel.
