Strap for MoonSwatch Mission to the Pink Moonphase

The Swatch MoonSwatch SO33P700 features 20mm lug width, the standard measurement for 42mm diameter watches. The lug width is measured by calculating the distance between the inner pins of the attachment points, verifiable with a digital calliper. Milano Straps provides exclusively tested and calibrated straps for this specification.

There is no universal choice—it depends on intended use and personal taste. A vegetable-tanned calf leather emphasises Speedmaster heritage with formal elegance; an aerospace-grade nylon NATO offers tactical versatility; an alligator leather in black with deployant clasp guarantees bespoke sophistication; a rubber FKM strap is ideal for sports contexts. Milano Straps stocks all these options in 20mm.

Strap replacement on the SO33P700 is accomplished via spring bars (spring pins) fitted to the lugs. Using a dedicated tool (spring bar tool), apply pressure towards the case centre to disengage the pin, then remove the previous strap and insert the new one, ensuring the pin clicks correctly on both sides. Do not force; inspect the lug housing visually before operation.

No. Although 20mm lug width is common, strap reliability depends on build quality, tolerance adherence, and aesthetic compatibility. Milano Straps certifies each 20mm strap for mechanical and visual compatibility with specific models, including the SO33P700. Using non-certified straps risks pin looseness or proportional incongruity.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 5-7 years with moderate daily wear. Longevity depends on UV exposure, humidity, usage frequency, and maintenance. Milano Straps' vegetable and vegetable-blend tanned straps develop a protective patina that improves over time. Annual conditioning is recommended to extend useful life.
