Strap for Speedmaster Professional Broad Arrow Moonphase Stainless Steel / Silver / Bracelet

The Omega Speedmaster Moonwatch 3575.30.00 has a lug width of 20 millimetres. This dimension is the standard for the model and allows the use of aftermarket 20mm straps without mechanical adaptations. To verify, measure the distance between the two lugs where the strap attaches to the case.

Ideal materials are black alligator for formal style, vegetable-tanned calfskin in cognac or burgundy tones for a warm effect, shell cordovan for those seeking visual density, and rubber for dynamic professional contexts. Each choice offers different aesthetic ratios with the white gold and steel case.

The Speedmaster Moonwatch is equipped with standard straight lugs of 20 millimetres. Strap replacement is performed using a spring bar tool to remove the elastic pins from the case attachments. Remove the old strap, insert the new one aligning the holes with the pins, and press until the pin locks into the attachments. No technical adaptation required.

Yes, all straps designed for 20mm lug width are compatible with the Speedmaster Moonwatch 3575.30.00. The case lugs maintain ISO 20841 standards, so mounting is plug-and-play. Choose based on the material and finish you prefer for your watch.

The lifespan of a leather strap depends on frequency of use and material. Quality artisanal alligator and shell cordovan settle in after 3-4 months and develop patina for 5-8 years before showing signs of structural failure. Vegetable-tanned calfskin lasts 4-6 years in daily use. During inactive months, store the strap away from moisture.
