Strap for Mission Timer U2

The Sinn 1020.010 features a lug width of 22 millimetres, measured between the two horizontal passage holes of the case. When selecting a replacement strap, verify that the width is precisely 22mm, with a maximum tolerance of ±0.5mm to ensure a snug fit without lateral play or excessive tension.

Selection depends on primary use. For diving and humid environments: vulcanised rubber or cordura NATO. For daily elegance with technical heritage: vegetable-tanned calf or shell cordovan. Natural alligator represents a sophisticated compromise between robustness and aesthetics. Avoid thin, delicate leather straps – they are incompatible with the case's ruggedness.

Obtain a spring bar removal tool. Remove the anchor spring from one side by inserting the flat end of the tool into the hole and lifting gently, then extract the lug pin. Repeat for the opposite side. Position the new strap by threading one lug pin first, ensuring the anchor spring clicks fully into the hole. Check for smooth movement before wearing.

Yes, any strap with 22mm lug width is compatible with the Sinn 1020.010. Milanostraps supplies certified straps in this dimension, built to Italian artisanal standards. Always verify width compatibility and material suitability with your intended lifestyle – the case's robustness deserves an equivalent strap.

A quality vegetable-tanned leather strap lasts 3–5 years with moderate daily use. Frequent exposure to saltwater, chlorine, and UV radiation reduces longevity to 2–3 years. Rubber and NATO straps offer superior durability (5–7 years) in marine environments. Regular maintenance – cleaning, drying, and occasional conditioning – significantly extends service life.
