Arnold & Son Royal TEC1 Tourbillon Chronograph Watch Japanese Movement Replica

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).

Technical Specifications

    The Arnold & Son HM Double Hemisphere Perpetual Moon’s crystal is anti-reflective sapphire and also the case back allows for more precise adjustments to the moon stage by demonstrating a third moon through eight distinct stages. Once installed, the precision should hold for 122 decades, after which an easy adjustment will ensure it for another 122 years. The hand-wound movement is an Arnold & Son fabrication A&S1512 that beats at 21,600 bph using a 90-hour power book. As if the case back weren’t amazing enough, the C?tes de Genève shown throughout the movement is merely lovely.The Arnold & Son HM Double Hemisphere Perpetual Moon comes with a black or brownish hand-stitched alligator strap and is sure to grab the attention of many an eye lover. When trying to fix a issue, the start is always a good place to start. That is exactly the procedure followed by Arnold & Son in their attempt to get rid of isochronal error from among their newest pieces, the Arnold & Son Constant Force Tourbillon. Arnold & Son’s heritage exists in the legacy of John Arnold and his son, two of the most important watchmakers to come from England. So admired was Arnold that Abraham-Louis Breguet himself delivered him his own son as an apprentice, while Arnold returned the favour. Having packed off his son to learn at the back of the Swiss maestro, Arnold turned his attentions to the problem of these times: the pursuit for chronometric accuracy at sea.
