Frequently asked questions
What is the lug width of the Oris Big Crown 01 754 7741 3168-07 5 20 58BR?
The lug width of this model is precisely 20 millimetres. This measurement is critical when ordering a compatible strap: it is measured as the distance between the internal lugs where the spring bars sit. A 20mm lug width ensures optimal proportions on the 40mm case and should not be confused with other Big Crown variants featuring 18mm or 22mm lugs.
What is the best strap for the Oris Big Crown 01 754 7741 3168-07 5 20 58BR?
There is no objectively 'best' strap, rather the choice depends on intended use and aesthetic preference. For an authentic tool watch, we recommend alligator with vegetable tanning (natural grain and patina development), artisanal calf leather (formal appearance and comfort), NATO cloth strap (aviation heritage and practicality), or vulcanised rubber (maximum sports functionality). MilanoStraps offers all these options in 20mm format.
How do I change the strap on an Oris Big Crown?
Strap replacement requires removal of the spring bars securing the strap to the case lugs. Using a spring bar tool, gently push the bar inward to unlock it, then the strap slides free. Installation of the new strap is reversed: the spring bar is inserted into the lug sockets, ensuring it is securely locked in place. If inexperienced, we recommend assistance from a qualified watchmaker.
Is an aftermarket strap compatible with the Oris Big Crown 01 754 7741 3168-07 5 20 58BR?
Yes, provided it is dimensioned precisely to 20mm lug width. Artisanal straps crafted by specialised ateliers such as Milano Straps are fully compatible and often offer superior quality to factory straps, with customisation options (leather type, hardware, stitching) unavailable from the manufacturer.
How long does a leather strap last on this watch?
Leather strap longevity depends on usage patterns and material type: quality artisanal calf with vegetable tanning may endure 3-5 years of daily wear, whilst alligator and shell cordovan can reach 5-7 years or longer thanks to inherent leather robustness. Factors including perspiration exposure, UV exposure and humidity influence ageing. Robust stitching and expert attachment significantly extend the accessory's lifespan.
