Strap for Big Crown Pointer Date 40 Stainless Steel / Black

The lug width measures exactly 20mm. This dimension is specific to the reference 01 754 7679 4034-07 5 20 78FC and is proportioned to the 40mm case to prevent visual overhang and ensure aesthetic balance. To verify, measure the distance between the lugs at the narrowest section (inner lug bore) using a digital calliper: you should find 19.8–20.2mm of precision.

For daily wear and formal occasions, a structured alligator with vegetable tanning or a high-quality calf leather harmonises perfectly with the satin-finished case texture. For sport and nautical use, a cotton-polyester NATO or vulcanised rubber strap ensures grip on wet wrist and protection against salt water. The ideal buckle is a deployante in satin-finished steel that mirrors the case finish.

Obtain a spring bar removal tool (rubber or steel implement). Position the flat end of the tool beneath the spring bar from the lug-strap side, press gently downward until the spring bar retracts, then slide the strap outward. Repeat on the opposite side. For installation, align the new strap with the lug hole, insert the spring bar and compress until you hear or feel the click.

Yes, any artisanal quality strap with a 20mm lug width is compatible with the Big Crown 01 754 7679 4034-07 5 20 78FC. On milanostraps.it you will find a curated selection of 20mm straps in alligator leather, calf, NATO and rubber, customisable in colour and finish. Always verify that the attachment thickness to the case body does not exceed 3–3.5mm to ensure correct lug positioning.

A high-quality leather strap (alligator, calf with vegetable tanning) subject to moderate use lasts 4–6 years before showing obvious signs of wear (cracking, loss of elastic resistance). Frequent exposure to water, intense humidity or direct sunlight reduces lifespan to 2–3 years. Rubber or synthetic NATO straps maintain structural integrity beyond 8–10 years if cleaned regularly and dried after immersion. Periodic maintenance (cleaning with damp cloth, conditioning with specific creams) significantly extends strap life.
