Strap for LadyMatic Co-Axial 34 Stainless Steel / Yellow Gold / MOP / Bracelet

The lug width of the 425.20.34.20.55.003 is exactly 20mm. This dimension was chosen by Omega to maintain optimal proportions relative to the 34mm case diameter, ensuring visual balance and wrist stability. Measure the internal distance between the lugs to verify compatibility before purchasing an aftermarket strap.

Alligator remains the most eloquent choice for a two-tone LadyMatic with mother-of-pearl: its compact grain and saturated colors naturally complement the yellow gold. Noble alternatives include vegetable-tanned calf leather (which develops patina over time) and shell cordovan for constructive density. Textured rubber is appropriate if you intend to emphasize the contained sports character, while maintaining a metal buckle in stainless steel or gold.

Strap replacement requires simple tools: a spring bar tool and a flat surface. Position the watch with the lugs facing you, insert the tool into the space between the lug and original strap, gently compress the internal spring and extract the strap. Repeat on the other side. Insert the new strap by aligning the holes with the lugs, then compress until you hear the spring bar click into place. If you prefer, entrust the operation to a professional to avoid scratches.

Yes, specific 20mm straps are compatible, provided they respect correct manufacturing tolerances. Not all 20mm straps on the market are suitable: imprecise tolerances cause excessive play or insertion difficulties. Rely on specialized suppliers like milanostraps.it who test compatibility with your model, or consult the Casati Milano atelier for custom-made artisanal straps.

A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 3–5 years with daily wear, depending on exposure to water, sweat, and lug wear. Vegetable tanning develops progressive patina and can last longer if properly cared for. FKM rubber ages less visually but becomes rigid after 5–7 years. Casati Milano guarantees 18 months on its own straps and recommends periodic maintenance with specific balms to extend useful life.
