Presented in a round 36mm case crafted from 18k white gold, the Patrimony 4100U/110G-B181 measures just 8.10mm in thickness — a profile that speaks to the collection's long-standing commitment to slim, classical proportions. The crown is likewise rendered in 18k white gold, maintaining a cohesive material language throughout.
A transparent sapphire caseback offers a clear view of the movement within, while the metal dial sits at the heart of the watch's clean, uncluttered aesthetic. Water resistance is rated to 3 bar, and the watch carries a round case shape that remains a hallmark of the Patrimony line.
The 18k white gold bracelet is finished in a combination of polished and satin surfaces, lending textural contrast to what is otherwise a study in restraint. Reference 4100U/110G-B181 represents the Patrimony at its most architectural — precise in form, deliberate in material choice.
