Strap for LadyMatic Co-Axial 34 Red Gold Diamond / Diamond Flower

The lug width of the 425.67.34.20.55.006 model is precisely 16mm. This is the internal distance between the two case lugs where the strap is attached. This dimension is specific to the contemporary generation of the LadyMatic and is not interchangeable with earlier versions of the model.

Natural alligator with vegetable tanning offers the best balance between tactile nobility and chromatic evolution parallel to red gold. Cognac shell cordovan guarantees intrinsic lustre and superior longevity. Brown vegetable calf is ideal for those seeking rapid patina development. For formal contexts, black alligator with blue thread maintains a minimalist profile.

Straps on this model are replaced via the case lugs (spring bar attachments). Use a precision tool to slightly compress the lug, insert the new strap, and release. Professional assistance from a jeweller or watchmaker is recommended to prevent scratches on the red gold case.

Yes, provided the internal width is certified at 16mm and the case lugs conform to the original design. Aftermarket straps still require personal verification before installation. We recommend personal verification or professional assistance to ensure optimal fit and protect the case.

An alligator or shell cordovan strap with vegetable tanning maintains structural integrity for 4–6 years of daily wear. Natural calf resists 3–4 years. Durability depends on exposure to perspiration, direct sunlight, and maintenance frequency. Periodic treatment with specific balms extends useful life by 12–18 months.
