Strap for Constellation Co-Axial 35 Yellow Gold / Champagne

The lug width of the Constellation 123.50.35.20.58.001 is 20mm. This dimension is critical for the compatibility of any aftermarket strap: it represents the precise distance between the two suspension pins of the case where the strap attaches. Always verify this measurement before purchasing a new strap to ensure perfect fit.

For the Omega Constellation 123.50.35.20.58.001 in yellow gold, vegetable-tanned alligator leather represents the most suitable choice from both aesthetic and constructive perspectives: its elegant texture and the natural patina that develops over time harmonize perfectly with the warmth of the precious metal. Shell cordovan is an excellent alternative for those seeking greater durability. For casual occasions, vegetable-tanned calf leather with medium grain offers versatility while maintaining the formal dignity of the model.

Strap replacement on this model is accomplished by extracting the suspension pins using a dedicated tool (spring bar tool). Position the watch on a stable surface, locate the tiny lateral holes on the case where the pins reside, and gently compress the pin using the tool to release the old strap. Then insert the new strap by aligning the holes in the lug to the case pins. If uncertain, contact an authorized Omega service center or a specialized craftsman to avoid damage to the case.

Yes, numerous aftermarket straps are compatible with the Constellation 123.50.35.20.58.001 as long as they respect the 20mm lug width. Milano Straps offers a dedicated collection of artisanal leather straps in natural leather, alligator, shell cordovan, and calf, all crafted to specifications compatible with this measurement. It is essential to always verify that the strap is explicitly indicated for 20mm lug width to guarantee proper fit without compromise.

The lifespan of a natural leather strap depends on frequency of wear, environmental conditions, and type of tanning. High-quality vegetable-tanned alligator worn daily maintains structural integrity for 3-5 years; shell cordovan can last 5-7 years thanks to the superior density of the leather. Calf leather straps with vegetable tanning develop patina and softening after 2-3 years of intensive use. Prolonged exposure to moisture, direct heat, and temperature fluctuations significantly shortens useful life. Casati Milano guarantees 18 months on their made-to-measure straps, covering any manufacturing defects.
