Frequently asked questions

What is the exact lug width of the Omega Constellation 123.13.35.60.60.001?

The lug width is 16mm. This measurement corresponds to the distance between the pins that support the strap to the lugs of the case. It is critical to ensure a perfect fit without lateral play or excessive compression. Measure it with a digital caliper or consult the official Omega technical specifications.

Which strap material is most suitable for the Constellation 123.13.35.60.60.001?

Nile alligator is the ideal choice to maintain the classic elegance of the watch. Alternatively, vegetable-tanned calfskin offers natural softness and patina over time. For more robust daily use, Japanese shell cordovan or jacquard textile NATO guarantee durability without aesthetic compromise.

How do I change the strap on my Omega Constellation 123.13.35.60.60.001?

It is necessary to use a spring bar tool to remove the elastic pins that support the current strap. Position the tool in the appropriate lateral groove of the pin, compress and extract. Insert the new 16mm strap aligning the holes with the pins, press until it locks into place. It is recommended to have a professional perform this operation to avoid damage.

Can I use aftermarket straps compatible with the 123.13.35.60.60.001?

Yes, provided the lug width is exactly 16mm. Artisanal straps from Milano Straps are specifically designed and tested for this model, with customization options in leather, color and stitching. They guarantee total compatibility and construction quality equivalent to Omega standards.

How long does a leather strap last on the Constellation 123.13.35.60.60.001?

Durability depends on intensity of use and material. Superior quality alligator or calfskin resists 3-5 years with moderate daily use. Shell cordovan can last over 7 years. Critical factors: sun exposure, sweat, humidity. Regular maintenance (conditioning every 6-8 months) and rotation between straps significantly extends the life of the product.
