Strap for Constellation Co-Axial 35 Red Gold / Silver Omega

The Omega Constellation 123.50.35.20.52.003 has a lug width of 18 millimetres. This dimension is specific to the 35mm model and must be measured from the inner part of one lug to the inner part of the other, perpendicular to the case.

For the Constellation 123.50.35.20.52.003 in rose gold, dark brown or cognac alligator represents the most versatile and elegant choice. The natural texture of the leather dialogues perfectly with the fluted bezel, while the colour enhances the warm tone of the rose gold. Alternatively, Japanese shell cordovan offers exceptional durability and a natural patina that develops with use.

To change the strap on your Constellation 123.50.35.20.52.003, use a spring bar tool (instrument with a rounded tip) to compress the internal springs of the lugs. Insert the tip into the lateral grooves of the lug, gently press to release the pin from its lower position, then remove the old strap. Insert the new strap following the reverse path, ensuring the pin is properly positioned on both sides.

Any strap with an 18 millimetre lug width is compatible with the Constellation 123.50.35.20.52.003. On milanostraps.it you will find a complete selection of customisable 18mm straps in leather, colour, sizes and thread colour, or you can request a bespoke strap from the Casati Milano atelier with 18 months warranty.

The lifespan of a leather strap depends on the type of leather and the intensity of use. A high-quality alligator or shell cordovan can last 4-6 years with daily wear, while a more delicate calf requires rotation with other straps for similar longevity. Factors such as humidity, perspiration and sun exposure influence ageing. The Casati Milano atelier offers 18 months warranty on bespoke straps and pin replacement services at reasonable cost.
