Strap for DS Acition GMT Powermatic 80 Stainless Steel - Yellow Gold / Black

The <a href="https://milanostraps.it/pages/termine-glossario/misura-ansa">lug width</a> is precisely 20 mm. This is a non-standard dimension requiring artisanal craftsmanship in strap manufacturing, as most producers stop at 18 or 22 mm. Always verify the case reference before ordering.

Given the tool-watch nature of this model, we recommend <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">vegetable-tanned leather straps</a> for understated elegance, or nylon NATO for tactical practicality. Vulcanised rubber proves excellent in humid climates. We advise against polished leather (alligator or glossy calf): the angular case deserves a matte foundation.

The Certina DS Action is equipped with standard 20 mm straight spring bars. Use a removable tool (spring bar tool) to compress the pin from one side, extract the old lug, insert the new strap. Do not force: the mechanism yields smoothly if correctly operated. We recommend strap changes at an atelier to preserve the case.

Absolutely. The 20 mm lug width permits total compatibility with bespoke artisanal straps. Milanostraps offers customisable straps in various finishes: vegetable-tanned dyed-in-the-mass, variable grain texture, deployante or classic buckle. Every strap is crafted to measure for this width.

A quality artisanal leather strap, subjected to regular maintenance (damp cleaning, natural wax treatment every 6–12 months), maintains structural integrity and patina for 3–5 years. Wear varies based on climate, frequency of use, and wrist-friction habit. Patina is not wear: it is the result of natural contact between skin and leather, a sign of authentic belonging.
