Frequently asked questions

What is the lug width of the Omega Constellation 1458.75.00?

The reference 1458.75.00 has a lug width of exactly 18mm. This measurement allows the use of any commercial strap in standard 18mm format, whether you choose a handcrafted solution in alligator or calf leather, or a technical strap in rubber or NATO. The measurement should be verified with a digital caliper between the lugs of the case to ensure correct compatibility.

Which strap is best suited for the Omega Constellation 1458.75.00?

For the delicate and feminine proportions of the 1458.75.00, a fine-grain alligator strap represents the most natural aesthetic choice. The material amplifies the understated refinement of the piece, allowing for subtle seasonal rotation between shades such as cognac, black, and taupe brown. Alternatively, vegetable-tanned calf leather offers authentic aging and natural patina development over time, creating a material dialogue with the satin-finished steel case.

How do you change the strap on the Omega Constellation 1458.75.00?

The strap on the 1458.75.00 is changed by removing the spring bars that connect the lugs to the case. Using a spring bar remover or a small screwdriver, apply gentle pressure to release the pin laterally, allowing removal of the original strap. Insert the new 18mm strap by aligning the holes with the lugs and reinserting the spring bar until it clicks into place. It is advisable to perform this operation with patience on a soft surface (cloth or mat) to avoid scratches.

Can I use an aftermarket compatible strap on my 1458.75.00?

Yes, the 1458.75.00 accepts aftermarket straps in 18mm format. It is important to verify that the strap is constructed with quality materials (genuine alligator, vegetable-tanned calf, FKM rubber) and that it features a robust deployant clasp in satin-finished steel or compatible with the case finish. A custom handcrafted strap made by the Casati Milano atelier guarantees perfect compatibility, superior construction quality, and an 18-month warranty.

How long does a leather strap last on a watch like the 1458.75.00?

The lifespan of a leather strap depends on frequency of use, climate, and material quality. High-quality alligator or calf leather maintains structural integrity for 3-5 years with daily wear, developing a natural patina that enhances its character. Exposure to perspiration, water, and UV rays accelerates wear. A handcrafted vegetable-tanned strap ages consciously, displaying signs of noble development; a technical FKM rubber strap resists longer while maintaining elasticity and color. Periodic maintenance with specific balms significantly extends lifespan.
