Strap for OutDoor 39 Protect Stainless Steel / Green / Fixolex ®

The Archimede Outdoor UA8239F-A4.1-H features 20mm lugs. This measurement is calculated between the inner shoulders of the lugs themselves. It is crucial to verify this dimension before ordering a strap, as different lug widths (18mm, 19mm, 22mm) will not fit correctly into the case.

The Archimede Outdoor UA8239F-A4.1-H, being a minimalist tool watch, accommodates straps in dark alligator (mud brown, black), vegetable-tanned calf leather, cotton NATO in grey-green, or black vulcanised rubber. Dark brown alligator creates maximum aesthetic contrast with the satinised steel; NATO maintains functional identity; rubber ensures total water resistance.

The strap is changed by extracting the spring bars located at both ends of the lugs, using a dedicated tool called a spring bar tool. Insert the tool tip into the vertical slot of the bar, push gently to release one end, extract the bar itself. The reverse operation applies the new strap. If unfamiliar with the procedure, a watchmaker can perform the change in minutes.

No, if the other watch has different lug width than 20mm. Compatibility is guaranteed only if the strap is explicitly designed for 20mm lugs. An 18mm or 22mm strap will not fit securely. Always verify that the strap is specifically described as compatible with 20mm lugs.

Leather strap longevity depends on material and use. An alligator with vegetable tanning lasts approximately 3-5 years of daily wear, developing natural patina over time. Robust calf leather has similar durability. Vulcanised rubber lasts longer (5-7 years) as it resists dryness and cracking. Regular maintenance (cleaning, conditioning) significantly extends strap lifespan.
