Strap for Big Crown Pointer Date 36 Stainless Steel / Black / Bracelet

The lug width of the Oris Big Crown 01 754 7749 4064-07 8 17 22 is 17 millimetres. This measurement represents the distance between the internal suspension pins and must be verified with a digital calliper before purchasing an aftermarket strap. An incompatible width will result in oscillation or excessive binding during strap replacement.

The ideal strap depends on your desired aesthetic. Alligator or virgin calf leather with vegetable tanning emphasises the classic aviation heritage of the Big Crown, whilst a NATO weave or ballistic rubber strap accentuates the sporty-functional character. For the 36mm case, we recommend materials without thickness exceeding 1.2–1.4mm to avoid visual disproportionality. A stainless steel deployant buckle completes the construction experience.

Remove the watch from the current strap using a spring bar tool (a small metal lever specifically designed for this purpose). Locate the two spring pins at the strap ends: gently push them downward with the tool, lifting the old strap. Insert the pins of the new strap into the lug spaces and allow the spring pins to snap into position. Check for absence of play before wearing the watch.

Yes, any strap with a 17mm lug width is compatible. On MilanoStraps, you will find bespoke leather straps in vegetable-tanned leather, shell cordovan, ballistic textiles and natural rubber, all with construction thicknesses optimised for the Big Crown profile. The Casati Milano atelier also offers chromatic and finishing customisation by appointment for specific requirements.

A high-quality vegetable-tanned leather strap has an estimated lifespan of 3–5 years with daily use, unless prolonged exposure to humidity or thermal shock occurs. Shell cordovan, being denser, reaches 5–7 years of service life. The patina of the leather will gradually accentuate the vintage character of the Big Crown. Periodic maintenance with natural balms (free of silicones) significantly extends the lifespan of the strap.
