Strap for Fifty Fathoms Tribute to Fifty Fathoms / Stainless Steel / Black / Black Canvas

The lug width of the Blancpain Fifty Fathoms 5015B-1130-52 is 23mm. This measurement is essential when purchasing an aftermarket strap. You can verify it by measuring the internal distance between the two spring bars of your current strap. Any strap with a different lug width will not fit the case correctly.

For the Fifty Fathoms 5015B-1130-52, we recommend dark alligator straps (black, brown, navy blue) for elegant daily wear, or shell cordovan for those seeking an exceptionally durable and luxurious-looking leather. If you use the watch for frequent diving, an FKM rubber or NATO fabric strap offers superior water resistance. With Casati Milano, you can personally select the material and finishing in the Milan atelier.

To change the strap, you must remove the two spring bars connecting the strap to the case. Use a dedicated spring bar tool to gently push the lateral pin until the end is released. Remove the old strap and insert the new one, ensuring the strap lugs align with the spring bars. If you are uncertain about the procedure, consult a professional watchmaker to avoid scratching the case.

Yes, you can use any aftermarket strap with a 23mm lug width. It is important to verify that the strap is of quality equivalent to the watch: we recommend materials such as vegetable-tanned alligator, shell cordovan, English calf leather, or FKM rubber to ensure durability and aesthetics consistent with the Fifty Fathoms' prestige. Casati Milano's handcrafted straps are specifically made for watches in this category.

The lifespan of a leather strap depends on the material and usage. An alligator or vegetable-tanned calf strap typically lasts 3-5 years with daily wear. Shell cordovan is notably more resistant and can last 5-7 years or longer if properly maintained. Exposure to water, perspiration, and UV rays accelerates aging. Casati Milano offers an 18-month warranty on manufacturing defects and can provide maintenance instructions to extend the strap's life.
