For collectors and connoisseurs of haute horlogerie, this masterpiece is a true spectacle to behold. Independent Swiss watchmaking from the Vallée de Joux, founded by Pierre Dubois and deeply connected to Dubois-Dépraz, one of the world’s foremost creators of high-end complications with over a century of expertise. The TNT Royal Retro is the only watch in the world to stage a relay of 6 retrograde seconds hands — a constantly moving ballet in which each hand takes a turn to measure 10 seconds before instantly jumping back to zero. The result is both technical marvel and visual theatre, a complication patented and unique to Pierre DeRoche. Crafted in Grade 5 titanium, solid 18K rose gold, and steel parts this creation is as robust as it is refined, measuring an impressive 47.5 mm yet perfectly balanced on the wrist.
