Strap for Militare Automatic Stainless Steel / Bronze / Leather

The lug width of the Anonimo Militare AM-1020.01.002.A02 is 20 millimetres. This measurement is determined by the distance between the two lugs that hold the strap to the case. To verify it, position a digital caliper perpendicular to the case, aligning it with the lateral lugs. Aftermarket 20mm straps are readily available and offer maximum aesthetic versatility.

There is no universally 'best' strap, but appropriate choices for each use case. For formal elegance, alligator with vegetable tanning or shell cordovan develop natural patina over time. For operability and durability, nylon ballistic NATO remains unbeatable: waterproof, resistant to extreme temperatures, ideal for humid environments. Synthetic FKM rubber offers a compromise between comfort and functionality. Your choice reflects how you wish to interpret the instrument: a narrative of ageing or pure reliability.

The strap is secured to the case via two metal lugs (spring bar) that pass through the lug holes. To remove it, use a spring bar remover tool: insert the tip into the lateral opening of the lug, gently push to compress the internal spring, and slide the lug out of its housing. Repeat for the second lug. Install the new strap by reversing the process, ensuring that the lugs are fully inserted and the strap sits flush against the case. If you do not own the tool, professionals at Casati Milano atelier offer this service with watchmaking precision.

Yes, the Anonimo Militare AM-1020.01.002.A02 is fully compatible with aftermarket 20mm straps from any reputable manufacturer. The 20mm lug width is an international standard that enables access to an extensive catalogue: from ballistic NATOs to vegetable-tanned leather straps, from rubber models to alligator designs. The key is to verify that the strap is specifically sized for 20mm and that the spring bars used are of the correct length (typically 14-16mm). Milano Straps holds a curated selection of 20mm-compatible straps, tested and certified.

Durability depends on construction quality, tanning method, and declared use. A vegetable-tanned leather strap of watchmaking quality (alligator, calf, shell cordovan) typically lasts 3-5 years of regular daily wear before requiring replacement. Stitching remains intact for 5-7 years if made with high-quality waxed linen thread. Aesthetic patina begins to manifest after 2-3 months of consistent wear. If you wear the strap occasionally, durability extends proportionally. Maintenance with vegetable-based balms or leather oils extends the overall lifespan of the artefact.
