Strap for Speedmaster Broad Arrow Red Gold / Black / Bracelet

The Omega Speedmaster Broad Arrow 3153.80.00 features a lug width of 20 millimetres. This dimension is measured between the inner lugs of the case and is the standard construction specification for this model. Any 20mm strap is fully compatible with this reference.

For an Omega Speedmaster Broad Arrow 3153.80.00 in 18-carat rose gold, dark brown or black alligator represents the most sophisticated solution: the natural texture of crocodile skin creates balance with the precious metal, while vegetable tanning allows for patina development over time. For summer versatility, cognac-coloured cordovan or vulcanised black FKM rubber offer flexibility.

Strap replacement is performed by removing the spring bars using a dedicated tool called a spring bar tool. After placing the watch on a soft cloth, position the tool under the pin, lift slightly and extract the old strap from the lugs. Insert the new strap at the same points, ensuring that the pins lock securely. For precision and safety, we recommend entrusting the task to a professional watchmaker or the Casati Milano atelier.

Yes, any strap manufactured to the 20mm lug width specification is fully compatible. Compatibility depends on correct execution of the total length and the build quality of the leather or material chosen. Milano Straps offers a selection of customisable 20mm straps, from alligator leather to cordovan, crafted to elevated manufacturing standards.

The lifespan of a leather strap depends on construction quality, tanning and usage. An alligator or cordovan strap with vegetable tanning resists 4-7 years with regular daily wear, developing attractive patina over time. Lower-quality materials degrade within 2-3 years. The 18-month warranty offered by Casati Milano covers manufacturing defects, not natural wear.
