Strap for Constellation Quartz 27 Polished Stainless Steel / Yellow Gold / Champagne Supernova

The Omega Constellation 123.20.27.60.58.002 has a lug width of 20mm. This width, measured between the two horizontal attachment points where the strap connects, is specific to this model and determines the compatibility of all aftermarket straps.

For the Constellation we recommend alligator in warm tones (cognac, honey) for formal elegance, smooth calf for contemporary minimalism, or canvas NATO for everyday versatility. The choice depends on your intended use and personal style. Compatibility is guaranteed only with 20mm straps.

The strap is changed by gently extracting the spring bars that secure it to the case. You will need a specialized tool (spring bar tool) to compress the small spring pin and release it from the attachments. Consult our complete tutorial or contact Casati Milano for personalized assistance.

Yes, absolutely. As long as the strap is compatible with the 20mm lug width, it is completely safe to install. Milan Straps are handcrafted, made with certified leathers and controlled stitching. We also offer customization in sizes, initials, and thread choice.

A quality natural leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with regular use and proper maintenance. Factors such as climate, frequency of use, and care affect longevity. Casati Milano straps include an 18-month warranty and can be restored through professional reconditioning.
