The lug width of the Constellation 131.25.29.20.58.001 is 18mm, standard for this 29mm case model. This width is integrated into the case and determines compatibility with specific aftermarket straps.

Which strap is recommended for the Omega Constellation 131.25.29.20.58.001?

To enhance the elegance of the two-tone gold-steel Constellation, we recommend alligator in brown tones, black calf or shell cordovan. Alligator amplifies the formal character, calf offers daily versatility with a patina that evolves over time, and cordovan creates a luxurious contrast with the yellow gold.

How do you change the strap on the Omega Constellation 131.25.29.20.58.001?

Position the watch on a soft surface, locate the spring bar lugs beneath the case, then use a spring bar tool to compress the thin springs of the lugs and slide the strap out of the lugs. Reinsert the new 18mm strap by clicking the spring bars into the housings.

Which aftermarket strap is compatible with the Constellation 131.25.29.20.58.001?

All straps with 18mm lug width are compatible with the Constellation 131.25.29.20.58.001. On milanostraps.it you will find a selection of artisanal straps in natural leather, rubber and NATO specifically sized for this measurement.
