Frequently asked questions
What is the lug width of the Oris Big Crown 01 754 7798 4068-07 8 20 06?
The lug width (ansa width) of the Big Crown 01 754 7798 4068-07 8 20 06 is precisely 20 mm. This measurement is rigid and tolerates no variance: the case lugs are spaced exactly 20 millimetres apart. A strap with a different lug width will create visual gaps or fail to fit correctly into the spring bar holes.
Which strap is best for the Oris Big Crown 01 754 7798 4068-07 8 20 06?
No single strap is 'best'—only informed choices aligned with your use-case. Vegetable-tanned alligator delivers formal aesthetic excellence; vegetable-tanned calf offers daily versatility and comfort; NATO represents the instrument's historical heritage as a working pilot's tool; technical rubber dominates marine and sports environments. Your selection depends on context and the visual patina you wish to develop over time.
How do I change the strap on my Oris Big Crown 01 754 7798 4068-07 8 20 06?
The process is straightforward: locate the two spring bars (pins) connecting the strap to the case at 12 and 6 o'clock positions. Using a spring bar remover tool or fine implement, press the small indentation beneath each pin whilst gently moving it towards the case edge. The pin will retract and the strap will release. Insert the new strap's pin into the hole: the internal spring will retain it. Repeat for the second pin.
Can I use aftermarket straps (non-Oris branded) on my Big Crown?
Yes, provided the lug width is exactly 20 mm. Milanostraps artisan straps guarantee constructive precision: every design is tested on compatible cases. Aftermarket strap use does not void Oris warranty and permits aesthetic personalisation beyond official catalogue constraints. Always verify that lugs are straight and the strap engages securely in the spring bar pins.
How long does a leather strap last on an Oris Big Crown?
A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3–5 years in daily wear, depending on humidity, perspiration exposure, and cleaning frequency. A black vegetable-tanned strap develops visible patina after 12–18 months of consistent wear. Exposure to intense perspiration (sports) or marine salt water can reduce lifespan. Technical rubber performs significantly longer—7–10 years—but loses elasticity under prolonged UV exposure.
