This year, Arnold & Son is celebrating its 250th anniversary and to mark the occasion they have announced the latest addition to their Royal Collection, the Royal TEC1. To prove Arnold & Son’s commitment to Haute Horologerie, the TEC1 integrates three complications never seen before a timepiece produced by the brand: a tourbillon, a column wheel chronograph and an automatic winding system.
There are three versions of the Royal TEC1, an 18-carat red gold model with anthracite dial, a palladium cased version with a silvery white and silver dial and finally a limited edition 250th anniversary piece in 18-carat red gold 45 mm case featuring a blue lacquered guilloché dial.
The dial, between 10 o’clock and 2 o’clock is dominated by the tourbillon cage, while its lower half, at 6 o’clock is used for a 60 minutes chronograph counter. The seconds counter is offered by the central second hand. The case back is a see-through sapphire crystal, offering a generous view of the column wheel chronograph movement.
The TEC1 is powered by a 255-part, 30-jewel A&S8305 calibre, the brand’s first high-frequency tourbillon, with 28,800 vibrations per hour and with a generous power reserve of 55 hours. Each palladium treated movement boasts manually chamfered bridges with polished edges, fine circular graining and Côtes de Genève rayonnantes. The chronograph levers are satin-finished with hand-chamfered, polished edges and all screws are blued with bevelled and mirror polished heads. The highlight of each watch is a 22-carat red gold skeletonised rotor that is breathtakingly beautiful thanks to hand-engraved craftsmanship, its brushed surfaces and chamfered polished edges.
