Housed in a round 36mm case crafted from 18K 5N pink gold, the Patrimony 4100U/001R-B180 measures a slender 8.10mm in thickness. The crown shares the same pink gold composition, while a sapphire glass transparent caseback offers a clear view through to the movement within. Water resistance is rated to 3 bar.
The metal dial is complemented by a purple alligator Mississippiensis strap, secured by an 18K 5N pink gold ardillon buckle — a refined finishing touch that carries the warmth of the case material all the way through the design.
Reference 4100U/001R-B180 represents the Patrimony collection's characteristic restraint: clean proportions, precious materials, and carefully considered details across every component of the watch.
