Strap for OutDoor 39 Protect Stainless Steel / Green / Leather

The Archimede Outdoor UA8239-A4.1-H has a lug width of 20mm. This dimension is critical for compatibility: an undersized strap will slip from the case, while an oversized strap will not fit into the lugs. You can verify it by measuring the space between the side lugs of the case.

The choice depends on intended use. For formal elegance, we recommend vegetable-tanned leather in brown or alligator. For operational versatility, a NATO strap in black or grey nylon Cordura. For extended technical contexts, fluoroelastic rubber with stainless steel brushed deployante. The Outdoor deserves a strap that shares its functional sobriety, without gratuitous ornamentation.

Place the watch on a soft surface. Locate the bayonet springs on each side of the case, near the lugs. Using a flat tool (small knife or dedicated tool), apply gentle pressure outward on the spring to unlock the strap. Pull the strap outward and remove the metal tube. Repeat on the opposite side. Install the new strap by aligning the tube with the lug and pressing until you feel the spring click into place.

Yes, provided it respects the 20mm lug width and the thickness is consistent with the side lugs. Not all 20mm straps made for other brands maintain the same thickness tolerances. Before purchasing, verify that the supplier certifies compatibility specifically with Archimede and confirms the measurements from the case.

A quality leather strap (vegetable-tanned or alligator) typically lasts 4-7 years with daily use, depending on exposure to moisture and perspiration. Vegetable-tanned leather ages in a controlled manner, developing patina and tonal variations. Alligator resists prolonged contact with liquids better. Periodic maintenance (cleaning with a dry cloth, occasional nourishment with specific balm) extends strap lifespan by 30-50%.
