Strap for Constellation Master Chronometer 41 Stainless Steel - Ceramic / Silver Meteorite

The lug width of this model is 20 millimeters. This dimension is the standard value for the 41mm Constellation case and represents the space between the case lugs where the strap is inserted. It is one of the most common measurements in modern watchmaking and offers a wide choice of compatible aftermarket straps.

For this model we recommend high-quality alligator or calf leather straps. Black alligator, especially with a polished finish, amplifies the visual contrast with the meteorite dial and ceramic bezel, creating formal harmony. Calf represents an elegant alternative if you prefer a more discreet texture. Shell cordovan worked with vegetable tanning is also excellent, offering a natural patina that evolves over time.

Omega uses standard spring bars on this model. You will need a dedicated tool (a small screwdriver or spring bar tool). Gently insert the tip of the tool into the lug opening, apply light pressure to open the spring, and remove the strap. Insert the new strap in the same manner. If you are not experienced, we recommend entrusting the task to a professional watchmaker or the Milano Straps team.

Yes, the 20mm straps available on Milano Straps are fully compatible with your Omega Constellation 131.30.41.21.99.001. However, we recommend verifying that the lugs are indeed 20mm before purchase. Milano Straps also offers customization options (initials, thread color, length) and an 18-month warranty through the Casati Milano atelier.

The lifespan of a leather strap depends on the material and usage. A high-quality alligator or shell cordovan strap can last 5-7 years with daily wear, also considering natural aging (patina) which increases its appeal. Calf tends to have a slightly shorter lifespan, around 3-5 years. With proper maintenance (periodic cleaning, drying in case of moisture) and rotation with other straps, longevity increases significantly. Milano Straps provides an 18-month warranty on customized straps.
