Jacob & Co.’s Arlequino: A Gemologist’s Take on Diamonds in Motion
Oris
Founded in 1904 in Hölstein, Switzerland, Oris is one of the few independent Swiss watchmakers dedicated exclusively to mechanical timepieces. Guided by its philosophy of creating watches that “make sense,” the Maison combines traditional craftsmanship with meaningful innovation. Its in-house Calibre 400 exemplifies this approach, offering a five-day power reserve, high anti-magnetism, 10-year service intervals and a 10-year warranty.
