Meet the new Big Crown Calibre 473
It’s powered by a new hand-wound calibre, our tenth in-house movement in 10 years.
Calibre 473 has a five-day power reserve with an indicator on the reverse, it’s highly anti-magnetic.
Oris has developed a sophisticated stainless steel butterfly folding clasp with a fine adjustment system. It allows you to adjust the strap as your wrist expands and contracts, which happens as environmental conditions change.
