As a preview of BaselWorld 2013 novelties, Arnold & Son presented the new HMS1 Royal Blue finished with an intricate guilloché pattern overlaid by translucent deep blue lacquer which creates a nice contrast with the 40 mm rose gold case.
The HMS1 Royal Blue houses the hand-wound A&S1001 calibre, with a Côtes de Genève rayonnantes decoration. The movement is made of rhodium-treated nickel silver with haute horlogerie finishing, including hand-chamfered bridges with polished edges, fine circular graining and blued screws. The two barrels offer a power reserve of 80 hours.
The HMS1 Royal Blue is also available in an 18-carat rose gold model featuring a bezel set with 80 diamonds.
