Strap for Big Crown Pointer Date 40 Stainless Steel / Movember 2018

The lug width of the 01 754 7741 4037-Set LS model is 20 mm. This measurement represents the distance between the two lugs protruding from the case at 12 and 6 o'clock positions. It is essential to measure this dimension precisely before purchasing an aftermarket strap to ensure perfect compatibility.

For this Big Crown, we recommend alligator leather with vegetable tanning for technical elegance, satin-finished calf leather for refined everyday wear, cotton-polyester NATO straps for versatility and quick changes, or vulcanised rubber for aquatic and sports environments. The choice depends on intended use and wearing context.

To change the strap, position the watch on a soft pad with the case facing upward. Locate the springbars securing the strap to the lugs. Using a dedicated tool—such as a spring bar removal tool—compress the bar and extract the old strap. Insert the new strap of the same width (20 mm) and release the bar so it snaps back into place securely. Verify the attachment is secure before wearing the watch.

Yes, you can use any strap with a 20 mm lug width, provided it is built to a quality standard consistent with the instrument. Specialised artisanal strap makers offer options in fine leathers, technical fabrics, and rubber, crafted with meticulous attention to detail and compatible with the Big Crown's standard springbars. Always verify the correct measurement before purchase.

The lifespan of a leather strap depends on the quality of the leather, the type of tanning, and the intensity of use. A strap in alligator or vegetable-tanned calf leather, worn daily, can last 3-5 years before showing significant wear. Premium leather develops a natural patina that enhances aesthetic appeal over time. Regular maintenance—gentle cleaning and conditioning—substantially extends strap life.
