Arnold & Son will debut a new version of their Royal TEC1 timepiece, with a palladium case and guilloché, at Baselworld in March.

The TEC1 combines a high frequency tourbillon (4Hz), column wheel chronograph with central seconds counter and a bi-directional winding rotor. The 30 jewel in-house movement (caliber A&S8305) has 255 parts and a 55-hour power reserve. The bridges, main plate and many of the components have been treated with palladium. (Editor’s note: Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals.)

The bridges are manually chamfered with polished edges, and are decorated with either a fine circular graining or Côtes de Genève rayonnantes. The main plate is decorated with fine circular graining. The chronograph levers are satin-finished with hand-chamfered, polished edges and screws are blued with bevelled and mirror polished heads. A 22K red gold, hand-engraved, skeletonized rotor stands out against the silvery white palladium finish of the movement bridges and main plate.

The 45 mm diameter palladium case has a stepped bezel and is fully polished to a mirror finish. The dial features a black enamel wave guilloché pattern, except between 10 and 2 o’clock, which is where the tourbillon is displayed. The flange has a printed 60-second scale for reading the elapsed time from the chronograph central second hand. Polished, sword-shaped hour and minute hands, and facetted, polished hand-applied hour indices (except at 11, 12 and 1 o’clock), complete the design.

The Royal TEC1 is paired with a black alligator leather strap and will be available in a limited edition of 125 pieces, at a retail price of $99,000. (Ref. 1CTAG.U02A.C113G)
