Strap for Big Crown ProPilot Big Day Date PVD / Black

The Oris ProPilot 01 752 7698 4264-07 5 22 15GFC features a 22mm lug width. This measurement represents the distance between the two internal spring bar seats on the case and is the specific standard Oris selected to maintain proportional balance on this oversized tool watch. All 22mm straps are fully compatible with this reference.

Strap selection depends on primary use and context. For formal or elegant wear, we recommend vegetable-tanned Tuscan leather in hazelnut or deep black, or alligator in dark brown. For daily versatility and durability, a grey-black or charcoal NATO canvas offers waterproof practicality. For intense activities—sailing, outdoor exposure, humid environments—an FKM rubber strap with steel deployante buckle represents pure functional design without compromise.

To change the strap, you must remove the spring bars—the elastic pins securing the strap to the case. Using a dedicated spring bar tool or small screwdriver, gently press inward to release the pin from its housing. The old strap slides away. Insert the new strap by aligning its holes with the case's lug seats, then reinsert the spring bar, ensuring it clicks into position on both sides. A simple procedure anyone can perform at home.

Yes, any strap with a 22mm lug width is fully compatible. This means you can choose from dozens of artisanal options—leather, alligator, shell cordovan, NATO, rubber—from specialist brands. The universal compatibility of 22mm ensures your investment in the ProPilot is not bound to any proprietary Oris ecosystem, allowing you to completely transform the watch's appearance without limits.

Leather strap longevity varies with material quality, tanning method, climate, and continuous wear. Premium vegetable-tanned Tuscan leather can remain structurally sound for 3–5 years of daily wear. Beyond this period, leather typically shows deterioration signs (thinning, cracking). In highly humid environments or under intense perspiration, durability decreases. To extend lifespan, apply nourishing cream every 6–8 months and rotate straps to avoid concentrated stress.
