Strap for Constellation Co-Axial 35 Red Gold / Silver

The lug width of the Constellation 123.50.35.20.52.001 is exactly 16mm. This measurement is the distance between the two holes or lateral pins of the case where the straps are attached. It is essential to verify this dimension before purchasing an aftermarket strap, as even a 1mm difference results in total incompatibility.

For the Constellation 123.50.35.20.52.001 in 18-karat rose gold, we recommend alligator in dark brown or cognac tones: the natural grain texture dialogues perfectly with the formal elegance of the case, emphasizing its dressy character. Alternatively, shell cordovan offers tactile nobility and a patina that enriches over time, while vegetable-tanned calf leather guarantees natural and distinctive aging.

To change the strap on the Constellation 123.50.35.20.52.001, gently extract the lateral pins (spring bars) using a dedicated tool or a small flathead screwdriver. Position the watch with the inner side facing upward, locate the two metal pins transverse to the attachments, and apply gentle downward pressure to release them. Once freed, the strap or bracelet will detach easily. Insert the new strap by aligning the holes at the extremities and reinsert the pins until the safety click is felt.

Yes, absolutely. The Constellation 123.50.35.20.52.001 was designed by Omega with standard 16mm attachments, which means that any quality artisanal strap, provided it has the same lug width, will fit perfectly and securely. Milanostraps offers a complete collection of 16mm straps in fine materials – alligator, calf, shell cordovan, vegetable-tanned leather – all compatible and customizable according to your preferences.

The lifespan of a leather strap depends on the material, usage, and care. A quality alligator or shell cordovan strap, worn daily, lasts an average of 3-5 years before requiring structural replacement, although the patina continues to improve aesthetically. Calf leather, more delicate, may require replacement after 2-3 years if exposed to frequent sweat and humidity. Vegetable-tanned leather tends to age more rapidly in appearance but remains functionally robust for 4-6 years. Regular maintenance – clean the strap with a dry cloth, protect it from stagnant water, and rotate the position of the attachments – significantly extends its useful life.
