FAQ
What is the exact lug width of the Omega Constellation 131.20.39.20.52.002?
The Constellation 131.20.39.20.52.002 has a lug width of 24mm. This is the width you'll need to measure between the two lugs of the case to ensure that any aftermarket strap is compatible. Verify with a digital caliper positioned perpendicularly between the lugs at the top of the case.
What is the best strap for the Constellation 131.20.39.20.52.002?
For a dress watch of this elegance, alligator is the natural choice: its small and regular grain mirrors the sophistication of the guillochéd dial. Shell cordovan is an excellent alternative for those who appreciate natural patina and tactile richness. For versatility, vegetable-tanned calf offers durability and visible aging. Avoid saturated colors: choose black, dark brown, cognac, or tobacco to maintain aesthetic coherence with the two-tone case.
How do you change the strap on a Constellation 131.20.39.20.52.002?
The change occurs through the spring bars that lock the strap into the lugs. With a dedicated tool (spring bar tool), gently compress the bar from one side to release the lug attachment, then slide the strap out of the lug. Position the new strap by aligning the lug with the hole, then release the bar. A specialized atelier can perform this operation in just minutes without risk.
Which aftermarket straps are compatible with the Constellation 131.20.39.20.52.002?
Any strap with 24mm lug width is compatible. Milano Straps offers a complete collection of straps in alligator, shell cordovan, vegetable calf, NATO, and FKM rubber, all customizable in sizes, initials, and thread color choice. The Casati Milano atelier also creates bespoke versions with personal consultation.
How long does a leather strap last on a Constellation like this?
Durability depends on frequency of use, climate, and material. A quality alligator or shell cordovan strap, with moderate use and proper maintenance (avoid prolonged humidity and direct sunlight), typically lasts 4-6 years. Vegetable-tanned leather tends to age more visibly, but remains functional longer thanks to its robust structure. Milano Straps offers an 18-month guarantee on artisanal straps and technical support to extend your strap's lifespan.
