Founded in 1904 in Hölstein, Switzerland, Oris is an independent Swiss watchmaker renowned for its commitment to mechanical watchmaking, sustainability, and functional design. The Big Crown collection is one of Oris’s most iconic lines, originally created for pilots in the 1930s. The collaboration with Cervo Volante reflects Oris’s modern values, combining timeless design with responsible material sourcing.
The Oris Big Crown x Cervo Volante Grey, reference 01 754 7779 4063-Set, features a 38 mm stainless steel case paired with a refined grey dial made using natural pigments, resulting in subtle variations that make each dial unique. Applied Arabic numerals and cathedral-style hands filled with Super-LumiNova ensure excellent legibility. Powered by the Oris caliber 754 automatic movement (based on the Sellita SW200-1), it offers a 38-hour power reserve, a frequency of 28,800 vph, and functions including hours, minutes, central seconds, and a pointer date complication indicated by the signature red-tipped hand.
A domed sapphire crystal with anti-reflective coating protects the dial, while the oversized Big Crown ensures easy operation. With 50 meters of water resistance, the watch is well suited for everyday wear. This set is fitted with a sustainably sourced grey Cervo Volante deer leather strap and is supplied with an additional strap.
