Strap for De Ville Prestige Co-Axial 39.5 Stainless Steel / Red Gold / Vintage Silk Silver

The lug width is 20mm. To verify strap compatibility, measure the space between the two metal attachment lugs on the case using a digital caliper: the correct value is 20mm with a maximum tolerance of ±0.2mm. Do not confuse the width of the bar itself with the space between the bars.

Alligator leather with vegetable tanning is the most coherent choice for the Prestige positioning of this model. The regular grain texture, natural patina over time, and sweat resistance make it ideal for intensive professional use. Box calf represents an excellent alternative at lower cost; the FKM rubber strap is perfect for casual contexts and resistant to humidity.

Use a spring bar tool available at milanostraps.it. Position it under the lug retention spring, gently press upward to compress the spring, and simultaneously pull the spring bar out of the case. Repeat for the other side. Install the new strap by aligning the bars into the case holes and snapping the spring into place. Some prefer the <a href="/pages/termine-glossario/deployante">deployante</a> (push-button clasp) for quick wrist adjustment.

Yes, provided it is explicitly sized for 20mm. Many manufacturers offer universal straps, but only those certified 20mm will fit correctly into the lugs of this case. On milanostraps.it straps are catalogued by size: always verify that '20mm' is indicated in the product description.

A quality alligator strap (vegetable tanning) lasts 3-5 years with regular maintenance: monthly cleaning with a damp cloth, quarterly protection with neutral wax, thorough drying after rain or intense sweating. A standard calf leather strap lasts 18-36 months under the same conditions; vulcanized rubber exceeds 5 years. Longevity depends on ambient humidity and washing frequency.
