ATUM Enamel

バック

The ATUM watch family embodies all facets of pure watchmaking artistry. The enamelled dial of the ATUM Enamel is a further homage to artisanship in the days of old. Although traces of the art of enamelling can be found across millennia of art history, only very few masters of the discipline are capable — today as in the past — of creating immaculate enamelwork.

Manually crafted, lance-shaped hands add quintessential class to its overall personality. Despite its understated looks, it epitomises traditional craftsmanship and latest-generation engineering prowess.
