FAQ
What is the lug width of the Swatch MoonSwatch SO33N100?
The lug width of the Swatch MoonSwatch SO33N100 is 20 millimetres. This measurement represents the internal distance between the two lugs that connect the strap to the watch case. It is critical to measure this distance accurately before purchasing an aftermarket strap: a 19mm strap would have excessive play, whilst a 21mm strap would not fit into the case at all.
Which type of strap is most suitable for the Swatch MoonSwatch SO33N100?
For the bioceramic case of the MoonSwatch SO33N100, we recommend a vegetable-tanned calf leather strap fitted with a satin-finished titanium deployante. Calf leather evolves naturally over time, developing a patina that dialogues perfectly with the brushed finish of the case. For aquatic use or more sporty applications, FKM rubber or a nylon NATO offer superior moisture resistance and a contemporary texture coherent with the futuristic character of the model.
How do I change the strap on the MoonSwatch SO33N100?
The MoonSwatch SO33N100 features fixed straight lugs. To change the strap, position the watch on a soft pillow, and use a springbar tool to gently push the pins horizontally outward. Some models may have removable straight lugs: in this case, you can remove the entire lug and reinsert it into the new strap. Recommendation: have a professional watchmaker assist you the first time to avoid scratching the bioceramic case.
Are aftermarket straps compatible with the Swatch MoonSwatch SO33N100?
Yes, any strap with a 20mm lug width is compatible with the MoonSwatch SO33N100. On milanostraps.it you will find a selection of artisanal leather, NATO, and rubber straps, all tested and calibrated for the 20mm measurement. Quality aftermarket straps often offer superior finishes and materials compared to the original Swatch strap, whilst guaranteeing comfort and durability over time.
How long does a leather strap last on the MoonSwatch SO33N100?
A premium calf or alligator strap, vegetable-tanned, maintains structural integrity for 4 to 7 years with regular use and ordinary maintenance. Durability depends on climate, frequency of wear, exposure to humidity, and care practices. Avoid prolonged contact with chlorinated water. With proper maintenance—regular cleaning with a soft damp cloth and conditioning with specific balms 1 to 2 times per year—the leather develops a fascinating patina that characterises only truly cherished objects.
