Arnold & Son Royal TEC1 Tourbillon Chronograph Watch

By Jovan Krstevski

In honor of its 250th anniversary, the brand is adding the sophisticated  and new Royal TEC1 Tourbillon Chronograph to their collection of tourbillons. They stocked a column-wheel chronograph in the lower part of the dial with a 60-minute counter.


The in-house automatic chronograph movement A&S8305 is really something special. Beating at 28,800 vph and offers a power reserve of 55 hours, this manufacture movement features a high frequency tourbillon at twelve o’clock along with a column-wheel chronograph complication that offers a maximum measure of 60 minutes on a sub dial at six’ o clock. But the highlight of the rotor mechanism is 22K red gold, thanks to a stunningly beautiful hand-engraved and polished beveled edges.


The Arnold & Son Royal TEC1 comes in three versions: an 18K red gold with anthracite dial, a palladium with a silvery white dial, and a limited edition 18K red gold with blue lacquered gluilloché dial (that will be released later).
