Frequently asked questions

What is the lug width of the Omega Constellation 123.12.35.60.52.001?

The Omega Constellation 123.12.35.60.52.001 has a lug width of 20mm. This dimension is specific to the integrated case of 35mm and is determined by the internal distance between the lugs. It is essential to respect this exact measurement: straps of different widths will not fit the case correctly.

What is the best strap for the 35mm Omega Constellation?

It depends on intended use and desired aesthetics. For formal elegance, alligator or quality calf leather represent the preferred choices, as they enhance the dressy nature of the model. For everyday versatility, robust calf leather or Tropic rubber offer practicality without compromising visual balance. Shell cordovan is ideal if you desire a prestigious leather that develops patina over time.

How do you change the strap on a Constellation with an integrated case?

The Constellation features an integrated case, which means the lugs are not removable. To change the strap, you must thread the new strap through the case attachments. This requires care and, if you are uncertain, it is advisable to consult a professional such as Casati Milano atelier to avoid scratches on the case or damage to its finishing.

Are there aftermarket straps compatible with the Constellation 123.12.35.60.52.001?

Yes, all straps with 20mm lug width are compatible with this model. You can find quality leather, rubber, and fabric straps online, ready for shipment. Milano Straps offers a collection dedicated to 20mm straps, customizable in sizes, initials, and stitching thread, ensuring perfect fit to your case.

How long does a leather strap last on a watch worn daily?

Longevity depends on the quality of the leather and its use. A high-quality alligator or calf leather strap, subject to regular maintenance (gentle cleaning and occasional treatment with specific balms), can last 3-5 years of daily wear. Vegetable-tanned leather tends to age better than chrome-tanned leather, developing a noble patina. A Tropic rubber strap has a similar lifespan but is less prone to wear if exposed to sun and salt water.
