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

The lug width of this model is 20mm. This measurement corresponds to the distance between the inner shoulders of the case lugs and is essential for choosing a compatible strap. Do not confuse it with the case diameter, which is 27mm.

For this bicolour red gold-steel Constellation, we recommend black or brown alligator for aesthetic refinement, or cognac vegetable-tanned calf leather for everyday versatility. If you prefer practicality, a textured cotton NATO or rubber with deployant clasp are intelligent choices. The choice depends on your use: formal occasions suggest alligator, daily wear suggests calf leather.

Remove the old strap using a spring bar tool, inserting the bifid tip into the lug holes and gently levering outward. Once the spring bars are released, remove the old strap. To install the new one, align the strap holes with the bars and press inward with the same tool until the spring clicks into place. Verify that the bar is securely fixed before wearing the watch.

Yes, any strap with 20mm lug width is mechanically compatible. However, we recommend choosing leathers and finishes that respect the Constellation aesthetic: noble materials such as alligator and calf integrate better than synthetic leather. At Milano Straps you will find compatible straps specifically designed for ladies' watches in this category.

Durability depends on the material and usage. Quality alligator or calf leather, with proper maintenance (avoid immersion, protect from excessive moisture), lasts an average of 4-6 years in daily wear. A strap used occasionally can last 8-10 years. Rubber lasts longer (10-15 years) but still degrades over time. Milano Straps offers an 18-month warranty on its straps.
