Strap for DS-2 Powermatic 80 Stainless Steel / Black / Bracelet

The lug width of the C024.407.11.051.00 is 20 millimetres. This measurement is standard across the Certina Heritage collection, allowing you to fit aftermarket straps without structural compromise. Measure the lugs by positioning a rigid ruler perpendicularly between the two internal attachment points on the case.

The optimal strap depends on intended use. For formal elegance, we recommend alligator in warm tobacco brown or vegetable-tanned calf leather in black. For a sportier aesthetic, a dark blue or grey NATO strap maintains versatility. For casual wear, FKM silicone or natural off-white synthetic alcantara deliver practicality without compromising the dark dial's visual integrity.

The strap is changed using a spring bar tool or small lever attachment. Position the watch on a soft surface with the case facing downward. Gently slide the spring bar pin outward until it releases from the lugs. Remove the old strap and insert the new one, aligning the terminal holes with the case holes. Reinsert the pins until you feel a definitive click.

Yes, any strap with a 20mm lug width is fully compatible. Milanostraps offers an exclusive collection of artisanal straps in alligator, vegetable-tanned calf, NATO nylon, and FKM rubber. All meet standard 20mm tolerances and ship ready to wear. Spring bars are supplied separately or pre-installed according to preference.

A quality leather strap—alligator or vegetable-tanned calf—lasts 3–5 years with daily wear, depending on maintenance. Prolonged exposure to moisture, perspiration, and humidity accelerates deterioration. Periodic treatment with hydrophobic creams extends lifespan. NATO and FKM rubber straps offer superior durability (5–10 years) but require frequent cleaning to maintain suppleness.
