Frequently asked questions

What is the lug width of the Oris Big Crown 01 754 7779 4067-Set?

The lug width is precisely 19mm. This measurement must be respected rigorously: 18mm straps would exhibit excessive lateral play, whilst 20mm straps would not fit into the case lugs. We recommend verifying the measurement between the horizontal spring bar holes before ordering any aftermarket strap.

Which strap is best suited for the Big Crown 01 754 7779 4067-Set?

Selection depends on usage and aesthetic preference. For a formal-elegant appearance, we recommend alligator or vegetable-tanned shell cordovan, which develop natural patina over time. For everyday versatility, a smooth calf leather in neutral tones (black, brown) represents the ideal compromise. Those seeking uncompromising reliability may opt for high-density nylon NATO or technical rubber, perfect for sporting and humid environments.

How do I change the strap on the Big Crown 01 754 7779 4067-Set?

Remove the spring bars (the two elastic pins securing the strap to the lugs) using a dedicated tool, typically a small steel lever. Position the lever beneath the pin, gently push downward to compress the internal spring, and slide the pin out of its housing. Reverse the procedure to install the new 19mm strap, ensuring the pins lock completely into the lugs.

Can I use a compatible aftermarket strap on this model?

Yes, provided the lug width is exactly 19mm. A quality artisanal aftermarket strap, crafted from alligator, cordovan or certified calf leather, is not merely compatible but can impart new character to the watch. Verify that the manufacturer explicitly specifies 19mm and that the spring bars are installed correctly to ensure safety and functionality.

How long does a leather strap last on this watch?

A vegetable-tanned leather strap, used daily, has an average lifespan of 3-5 years before replacement is warranted. Shell cordovan, owing to superior density and resistance, may endure 6-8 years or longer. Longevity also depends on sunlight exposure, humidity and frequency of use. Rubber, by comparison, resists beyond 10 years under normal conditions, whilst nylon NATO guarantees nearly unlimited durability.
