Strap for Speedmaster Reduced Stainless Steel / Black / Bracelet

The lug width of the 3510.50.00 is 18mm. This measurement represents the distance between the two contact points of the lugs on the case of the crown. It is essential to verify this dimension at the time of purchasing an aftermarket strap to ensure proper fit without excessive gaps or tension on the case.

It depends on use and aesthetic preferences. Vegetable-tanned alligator represents the most sophisticated choice for elegance and the patina that develops over time. Shell cordovan offers natural luster and superior longevity. Vegetable-tanned calf guarantees immediate softness. For daily sports use, FKM rubber or NATO fabric ensure resistance and practicality without compromise.

The strap is changed using a spring bar tool, a specific instrument that allows you to compress the internal springs of the lug. Position the tool in the lateral notches under the lug, gently push inward to release the old strap, then insert the new one by snapping the springs into the watch's holes. It is advisable to perform the operation on a soft surface to avoid scratches on the case.

Durability depends on the quality of the tanning and use. A well-maintained alligator or vegetable-tanned calf strap lasts 3-5 years with daily use. Shell cordovan, due to fiber density, can last 5-7 years. FKM rubber maintains integrity for 4-6 years. Factors such as sun exposure, humidity and cleaning frequency directly influence longevity. A handcrafted strap with double stitching and manual workmanship tends to exceed wear expectations.
