Strap for Speedmaster Professional Plexi / Bracelet

The Omega Speedmaster Moonwatch 3570.50.00 has a lug width of 20mm. This is the standard distance between the case attachments, compatible with any strap or bracelet designed for 20mm. You can verify this measurement using a digital caliper positioned between the metal pins (lugs) on the sides of the case.

The Speedmaster Moonwatch pairs excellently with various materials. Alligator offers formal elegance with scale texture; calf leather ensures sobriety and clean aesthetics; the NATO strap returns the watch to its functional and spatial origins; rubber combines comfort and resistance to weather. The choice depends on intended use: leather strap for refined settings, NATO for a sporty or adventurous style.

The change is simple and requires no special tools. Position the watch with the case facing you. Locate the pins (lugs) on the sides of the case: they are small metal cylinders that run through the strap. Using a small punch or spring bar tool, gently press inward to release the pin spring. Once removed, the old strap comes free. Insert the new strap by aligning the holes at the ends and reinsert the pin until you feel the safety click.

Yes, many aftermarket straps are available for the 20mm size. MilanoStraps offers online a collection of artisanal straps compatible with this model, made from selected leathers (alligator, calf, shell cordovan) with custom finishes and personalizations upon request. The Casati Milano atelier also offers made-to-measure straps with direct consultation, guaranteeing construction quality and durability over time.

The longevity of a leather strap depends on the material, use, and care. An alligator or shell cordovan strap, with quality tanning, can last 3-5 years of regular use, developing a fascinating natural patina. Calf leather has similar durability, while straps in common leather may show wear sooner. Rotating between multiple straps (leather and NATO) significantly extends the life of each piece, allowing the material to dry between uses.
