Frequently asked questions

What is the lug width of the Swatch MoonSwatch SO33M102-104?

The lug width of the Swatch MoonSwatch SO33M102-104 is 20 millimetres. This measurement is specific to the model and reflects the proportions inherited from the original Omega Speedmaster. We recommend measuring the distance between the inner shoulders of the lugs to ensure compatibility with aftermarket straps.

Which strap is most recommended for the MoonSwatch SO33M102-104?

The choice depends on intended use and aesthetic preferences. A calf leather strap with vegetable tanning provides elegance and develops natural patina over time. NATO straps in ballistic nylon emphasise the military-space heritage. For contemporary intensive use, vulcanised rubber offers practicality and durability. All must have a 20mm lug width.

How do you change the strap on the Swatch MoonSwatch SO33M102-104?

The strap is replaced by removing the lugs from their seats on the case. Use a spring bar tool to gently push the spring bars towards the centre of the case, releasing them from their holes. Subsequently, insert the lugs of the new strap into the same holes until they lock. Delicate operation: proceed with caution to avoid damage to the caseback.

Which aftermarket straps are compatible with the SO33M102-104?

Any strap with a 20mm lug width is compatible with the MoonSwatch SO33M102-104. On milanostraps.it you will find a specialised selection of leather straps (alligator, calf, shell cordovan), NATO and rubber, all available in 20mm size, manufactured according to Italian artisanal standards.

How long does a leather strap last on the Swatch MoonSwatch SO33M102-104?

A quality leather strap (calf, alligator, shell cordovan) with vegetable or chromium tanning has an average lifespan of 3-5 years with moderate daily use. Longevity depends on sun exposure, humidity and frequency of use. Vegetable-tanned straps develop patina over time and are restorable. Periodic maintenance (hydration with appropriate balms) significantly extends durability.
