The Oris Big Crown X Cervo Volante 40mm (Ref. 01 754 7785 4068-Set) with a striking burnt sunset orange-to-red gradient dial is a highly sought-after, eco-conscious timepiece. It blends heritage aviation design with sustainable modern luxury through its collaboration with the Swiss sustainable leather house, Cervo Volante.

• The "Indian Summer" Gradient Dial: Features a stunning, warm reddish-orange center that transitions to a deeper, burnt autumnal shade on the outer rim. The pointer date hand is uniquely tipped with an inverted forest green arrow. 

• Vintage Case Geometry: Spans 40mm in diameter, 12.2mm in thickness, and 48.2mm lug-to-lug. It incorporates polished case sides, brushed lugs, and a signature coin-edge bezel. 

• Sustainable Deer Leather Strap: Crafted from ethically culled Swiss wild red deer hide that would otherwise be discarded. The mahogany-brown strap preserves natural grains and imperfections, meaning no two straps are identical.

• Reliable Caliber 754 Movement: Powered by an automatic, Sellita-based SW200-1 movement with a 41-hour power reserve and Oris's iconic red bi-directional rotor. It operates at 28,800 vph. 

• Robust Everyday Wear: Outfitted with a double-domed sapphire crystal (anti-reflective inner coating), an oversized screw-down crown, and 50 meters (5 bar) of water resistance.
