Strap for OutDoor 39 Protect Stainless Steel / Red / Rubber

The lug width of the Archimede Outdoor UA8239S-A6.1-H is 20mm. This measurement is verified by placing a digital calliper perpendicularly between the two lugs of the case. The 20mm width represents an harmonious proportion for the 39mm diameter case and requires specifically-sized straps not found in standardised ranges.

We recommend straps in vegetable-tanned alligator (fine grain, develops natural patina) or vegetable-tanned calf leather in medium brown or black tonalities. Alternatively, a grey or navy ECVS rubber strap is ideal for nautical contexts. The choice depends on primary use: refined aesthetics (alligator), urban versatility (calf), aquatic practicality (rubber).

To change the strap: 1) insert the lever pin into the small lateral cavity of the lug; 2) apply firm pressure outward to release the tension spring; 3) extract the spring bar pin; 4) remove the old strap; 5) insert the new strap through the upper lug, aligning the hole with the spring bar; 6) re-engage the pin by compressing the new strap. The operation becomes swift with practice.

All straps with 20mm lug width are compatible. milanostraps.it offers a complete collection of handcrafted straps in this width: Italian vegetable-tanned leather in vat colours, NATO fabric straps, FKM/ECVS rubber straps, and versions with stainless steel deployante clasps. Each strap is handmade and tested for compatibility with standard spring bars.

A high-quality handcrafted leather strap (alligator, vegetable-tanned calf, shell cordovan) subjected to daily wear typically lasts 3 to 8 years, depending on intensity of use and climatic conditions. Vegetable-tanned leather naturally develops creases and thinning over time, a sign of aesthetic rather than functional wear. A rubber ECVS strap has a lifespan of 5-7 years before elasticity diminishes. Regular maintenance (cleaning, conditioning with specialist balms) significantly extends longevity.
