Strap for Constellation Quartz 27 Polished Stainless Steel / Red Gold / MOP

The lug width of the 123.20.27.60.55.003 model is 16mm. This width requires straps specifically dimensioned to ensure precise anchoring to the case lugs without play or misalignment. Always measure the distance between the inner lugs with a caliper to confirm compatibility before purchase.

For the Constellation 123.20.27.60.55.003 with two-tone red gold and steel case, we recommend straps in medium brown alligator or cognac calf leather with vegetable tanning. Alligator enhances the jewel-like nature of the watch thanks to its natural grain texture and the patina it develops over time. For a more sporty aesthetic, calf leather with a satin finish offers elegant contrast with the two-tone without competing with the red gold.

To change the strap on the 123.20.27.60.55.003 model, remove the original spring bars using a spring bar tool from the lugs. Gently push the side pins inward with the tool to extract them. Once the lugs are freed, insert the new spring bars (or new bracelet if equipped with a deployant clasp) aligning them to the side grooves and secure the pins. Verify that the strap is symmetrical and firmly anchored before wearing the watch.

The lifespan of a quality leather strap on a daily-wear model like the Constellation 123.20.27.60.55.003 ranges from 3 to 5 years, depending on the tanning method, climate and frequency of use. Vegetable-tanned alligator ages more slowly than dyed calf, developing a fascinating patina. Milano Straps guarantees 18 months on bespoke straps created by the Casati Milano atelier and provides guidance for preventive replacement.
