Frequently asked questions
What is the lug width of the Oris Big Crown 01 745 7688 4361-07 5 22 73FC?
The lug width is 22mm. This dimension is specific to the 44mm Big Crown model and represents the optimal balance between visual proportions and constructive compatibility. Always verify by measuring directly from shoulder to shoulder of the spring bar attachment on the case.
Which strap do you recommend for this Big Crown?
It depends on use case. For aviation and dynamic activities: premium NATO in technical fabric. For daytime elegance: alligator or shell cordovan with vegetable tanning and natural ageing patina. For marine or extreme environments: FKM rubber with steel deployante. The brushed steel case pairs seamlessly with all three options.
How do you change the strap on an Oris?
Locate the two metal spring bars at the strap ends. Use a strap remover tool or thin implement to gently compress the spring bar downward, removing it from the lug slot. Insert the new strap aligning its lugs to the case holes, then reinsert the spring bars. Verify the strap is firmly secured before wearing.
Is an aftermarket strap compatible with the Big Crown 01 745 7688 4361-07 5 22 73FC?
Yes, if the lug width is exactly 22mm. Aftermarket straps of artisanal quality guarantee full compatibility provided the width matches. Avoid generic straps: prefer manufacturers who specify tanning method, leather type, weight, and thickness, ensuring constructive coherence with your watch's purpose.
How long does an artisanal leather strap last on an Oris like this?
A quality leather strap with vegetable tanning resists 3–5 years under normal daily wear conditions. Durability depends on usage frequency, sun exposure, humidity, and maintenance. Keep the strap dry after rain, clean monthly with a soft cloth and leather cleaner. The patina forming over time signals natural ageing, not deterioration.
