Frequently asked questions
What is the lug width of the Oris Big Crown 01 754 7741 3168-07 8 20 01?
The lug width of the Big Crown ProPilot is 20mm. This standard ensures wrist stability whilst maintaining balanced proportions with the 40mm case. It is crucial to verify the width before purchasing a strap, as even 1mm differences compromise compatibility and attachment fit.
Which strap type pairs best with the bronze Big Crown?
To enhance the aviator character and bronze patina, a vegetable-tanned leather strap in brown or cognac represents the most aesthetically coherent choice. However, a black alligator strap conveys formal elegance, whilst grey technical rubber emphasises the sporty vocation and use in demanding conditions.
How do you change the strap on this Oris?
The change is straightforward and requires no watchmaking expertise: a small lever tool (spring bar tool) is needed to extract the elastic pins that secure the strap to the case lugs. Light upward pressure releases the pin. The operation takes approximately 30 seconds per lug. Milano Straps supplies all straps pre-adjusted to the correct width.
Is an aftermarket 20mm strap reliable for the Big Crown?
Yes, provided it has been crafted by specialised artisans who understand manufacturing tolerances. A quality strap, featuring selected leather and double or triple stitching, often exceeds factory durability and longevity. Milano Straps works exclusively with suppliers guaranteeing premium components and manual quality control.
How long does a leather strap last on this watch?
Durability varies according to usage, material, and stitching. A good-quality vegetable-tanned leather strap withstands approximately 18–36 months of daily wear before showing failure signs (cracking, thinning). Technical rubber lasts 24–48 months. Vegetable tanning ages more nobly: leather softens and develops patina, whilst stitching remains the critical point to inspect periodically.
