Strap for LadyMatic Co-Axial 34 Yellow Gold / MOP

The Omega LadyMatic 425.62.34.20.55.003 has a lug width of 14mm. This measurement is critical when purchasing aftermarket straps for compatibility: measurement is performed with a digital caliper positioned perpendicular to the case axis, measured between the inner edges of the lugs. An error of just a few millimetres will render the strap incompatible with the case attachments.

For a yellow gold watch such as the 425.62.34.20.55.003, we recommend natural medium brown alligator (cognac tone) or vegetable-tanned calf in dark burgundy. Alligator maintains its starring role alongside the case, while vegetable-tanned calf develops a patina that echoes the natural ageing of gold. Shell cordovan guarantees superior durability, ideal for those seeking longevity without sacrificing elegance.

The strap on the LadyMatic 425.62.34.20.55.003 is changed by removing the spring bars that connect the strap to the 14mm lugs. Use a dedicated tool (spring bar tool) to compress the bars and extract them laterally. The procedure is reversible and does not require specialised watchmaking skills. We recommend specialised ateliers to verify alignment and correct tension after fitting.

Any strap with 14mm lugs is formally compatible. On milanostraps.it you will find a dedicated collection of 14mm straps in alligator, calf, shell cordovan, NATO and rubber, all tested for structural and aesthetic compatibility with the LadyMatic. Always verify the technical specifications from the seller before purchase.

Durability depends on material, usage and environmental conditions. Common calf: 3–5 years of daily wear. Vegetable-tanned calf: 5–8 years. Shell cordovan: 8–12 years. Natural alligator: 5–7 years. Factors such as sun exposure, humidity and cleaning frequency significantly affect longevity. The Casati Milano atelier offers an 18-month warranty on made-to-measure straps and advice on preventive maintenance.
