Strap for DS Action Lady 34.5 Stainless Steel / Blue

The lug width is precisely 18 millimetres. Measure the distance between the two spring bars emerging from the case lugs to verify compatibility with any strap. Even a 1mm deviation results in structural incompatibility.

Selection depends on intended usage: alligator or vegetable-tanned calf leather for formal contexts, NATO nylon for sport or daily wear, FKM rubber for aquatic activities. The ceramic and steel case benefits from straps that preserve the watch's construction aesthetics.

Using a spring bar tool, gently press downward on the retention pin from within the strap. The pin will release from the case lug. Insert the new strap into the lateral slots, then re-insert the pin until it clicks into position. Never force: the pin should slide smoothly.

Yes, provided it strictly respects the 18mm lug width. Verify that the strap's internal passants have the correct diameter for the case pins (typically 1.5–1.6mm). Quality aftermarket straps pose no risk of case damage.

A quality calf or alligator strap, with regular maintenance (avoiding prolonged moisture exposure, cleaning with dry cloth), lasts 3–5 years in daily wear. Vegetable-tanned leather develops natural creasing before modern tannage, but with proper care maintains structure and relative water resistance beyond 4 years.
