Strap for Constellation Quartz 27 Brushed Stainless Steel / Red Gold / Tahiti MOP

The lug width of the Omega Constellation 123.20.27.60.57.006 is 18 millimetres. This measurement is critical to ensure that the strap fits perfectly onto the integrated lugs of the case. Measure perpendicularly from the centre of one lug to the centre of the other using a digital calliper for maximum precision.

For this Constellation, the ideal strap is African alligator with vegetable tanning, which enhances the refinement of the 27mm case and the mother-of-pearl dial. Polished smooth calf is an excellent alternative for those who prefer a luminous patina. We advise against synthetic or NATO straps, which would compromise the aesthetic balance of the model.

The Constellation 123.20.27.60.57.006 features integrated lugs, which means the strap does not use removable spring bars. Strap changes must be carried out by a professional watchmaker who has the specific tools to separate the new strap from the soldered or riveted lugs. Casati Milano offers this service with personalised consultation.

Compatible aftermarket straps must be made specifically for an 18mm lug width and feature integrated lugs (not removable bars). Milano Straps offers a complete collection of 18mm straps customisable for this model, with options in alligator, calf and artisanally vegetable-tanned leather.

A quality leather strap, made with artisanally vegetable-tanned leather, has an average lifespan of 4-6 years with daily wear. Longevity depends on the quality of the tanning, ambient humidity and wearing habits. Milano Straps provides an 18-month warranty and recommends periodic maintenance to extend the life of the strap.
