Frequently asked questions

What is the lug width of the Omega Constellation 1571.51.00?

The lug width of the Constellation 1571.51.00 is exactly 18mm. This is the distance between the case lugs where the strap attaches. Measuring the lug width is simple: position a ruler perpendicular to the case edges, between one lug and the other, without touching the case itself.

What is the best strap for the Omega Constellation 1571.51.00?

The choice depends on your intended use. For evening elegance, alligator with vegetable tanning is unmatched. For daily business wear, vegetable-tanned calf offers comfort and develops a beautiful patina over time. For dynamism and quick changes, NATO is ideal. FKM rubber is the solution for those who prefer durability and zero maintenance.

How do you change the strap on the Constellation 1571.51.00?

The Constellation 1571.51.00 features an integrated bracelet. To change the strap, you need to remove the side loops (if present) or have specific lugs installed. We recommend contacting Casati Milano atelier for this operation, to ensure proper fit and case protection.

Are there aftermarket straps compatible with the 1571.51.00?

Yes, all 18mm straps are compatible with the Constellation 1571.51.00. On milanostraps.it you will find a wide selection of straps in alligator, calf, NATO and rubber, customizable in sizes, initials and stitching thread color.

How long does a leather strap last on the Omega Constellation 1571.51.00?

A quality leather strap with vegetable tanning has an average lifespan of 3-5 years with regular daily use. Alligator tends to age better than calf, developing an aesthetic patina. Longevity depends on maintenance, frequency of use and exposure to moisture. Casati Milano guarantees its artisanal straps for 18 months.
