Roger Dubuis Golden Square Tourbillon ref. G40 030 N1.63 – 18k White Gold, 04 of 28 made, MoP dial


Another special piece by Roger Dubuis – ref. G40 030 N1.63 – the Golden Square Tourbillon is the watch every collector would love to see in his possession. It is a beautiful square timepiece, made out of 18k White Gold in a 41 mm square form factor. The dial is a mesmerizing Mother-of-Pearl one, with a big date display under the 12 o’clock index, a power reserve meter at 4 o’clock and the mighty Tourbillon, proudly shown between 6 and 9 o’clock. It’s powered by the Roger Dubuis caliber RD03, which has been finished with the proficiency of the finest artisans working in watchmaking today, having had every single one of its components built entirely inhouse. The finishing is easily on par with even the most impressive achievements of haute horology – Most of that can be observed through the see-through caseback. It is a limited edition – 04 of 28 timepieces totally made. MSRP was ~180 000 €. The condition of our offering is superb, with only a few hairpins to found, mainly on the buckle. Comes on the original black crocodile leather strap with a 18k White Gold tang buckle. Ticking perfectly. In full set – with all the boxes, papers and tags.

Covered by a limited warranty of 1 year, starting on the date of purchase.
