Strap for OutDoor 39 Protect Stainless Steel / Blue / Bracelet

The Archimede Outdoor UA8239B-A3.1-H features a lug width of 20mm. This specification allows the use of any aftermarket strap compatible with 20mm lug width watches. To measure correctly, insert a flexible ruler into the lug seat from outer edge to outer edge.

For a watch of this constructive philosophy, we recommend a vegetable-tanned leather strap, preferably in dark brown or black, as the patina evolves naturally over time. Alternatively, a natural rubber or nylon NATO strap provides functionality for sporting contexts while maintaining the austere identity of the model. Avoid highly glossy or decorative materials.

The strap is replaced by removing the lateral pins that secure it to the lugs. Use a dedicated spring bar tool to access the pins without damaging the dial. Align the new strap's holes with the lugs, then secure the pins. For fine watches, we recommend entrusting this operation to a professional.

No. For the UA8239B-A3.1-H, you must exclusively use straps with 20mm lug width. Although the case diameter is 39mm, compatibility depends on lug width, not diameter size. Always verify this specification before purchase. Our straps are specifically crafted for 20mm lugs.

A quality artisanal leather strap, used daily, typically lasts 2-3 years. Durability depends on frequency of use, climate conditions, and maintenance. Vegetable-tanned leather develops a natural patina that improves aesthetics over time. When the strap shows significant wear (cracks, detachment), replacement is warranted. We recommend periodic cleaning with a soft cloth and neutral wax.
