Strap for De Ville Prestige Co-Axial 39.5 Power Reserve Stainless Steel / Ivory / GUM Red Square

The lug width measures 20 mm, which is the distance between the two case attachment pins. This dimension is standard on many classic Omega models and ensures compatibility with specialized artisanal straps. To verify it, use a digital caliper measuring from outer edge to outer edge of the pins, maintaining the reference perpendicular to the case plane.

Medium brown alligator with natural tanning is the reference choice for this reference, as the grain consistency and natural patina coherently complement the elegant construction of the sunburst steel case. Valid alternatives include excellence calf with vegetable tanning, shell cordovan for those who appreciate materials that transform over time, and FKM rubber for high-dynamicity daily-wear contexts.

The attachment pins must be removed using a professional spring bar tool. Position the watch on a table with the crystal facing upward, locate the small lateral holes beneath each pin, insert the tool into the grooves and gently push outward to release the pin. Repeat for both sides. For installation of the new strap, insert the pins into the leather loops and reposition them in the case lugs until an audible locking click occurs.

Yes, provided that the lug width is exactly 20 mm and that the strap's construction quality is consistent with the watch's standard. Artisanal straps in alligator, calf with vegetable tanning, shell cordovan or FKM rubber are fully compatible. Avoid generic low-quality straps that would compromise the watch's aesthetics and wearability.

A superior quality artisanal leather strap, worn daily with regular maintenance (leather hydration every 6 months), guarantees an average lifespan of 5-7 years before replacement is needed. Shell cordovan, due to its dense structure, can exceed 10 years. Vulcanized FKM rubber has a lifespan comparable to natural leather but resists external agents better. A Casati Milano strap includes an 18-month warranty on manufacturing defects.
