Strap for Constellation Quartz 27 Brushed Red Gold / Diamond / Brown Supernova

The lug width measures exactly 20mm. This dimension represents the distance between the pins (bayonets) at the attachments and must be strictly respected when choosing an aftermarket strap to ensure compatibility and prevent damage to the watch lugs.

For a 27mm rose gold case, cognac alligator represents the most harmonious aesthetic choice. Vegetable-tanned anilina calf leather constitutes a sophisticated alternative for those preferring an evolving patina over time. Shell cordovan offers resistance and naturally develops burgundy tones over the months.

Equip yourself with a spring bar removal tool and position the watch on a soft surface. Gently push the pins inward to release them, then remove the old strap. Align the new strap with the pins and push until it clicks into place. If inexperienced, consult a professional to avoid scratches on the precious case.

Yes, any strap with a 20mm lug width is compatible with this reference. However, it is advisable to choose appropriate thicknesses (approximately 3.5-4mm) to ensure correct seating in the lugs and balanced aesthetic proportion relative to the 27mm case.

A quality leather strap, properly maintained, has an average lifespan of 3-5 years under daily use conditions. The material, tanning method (vegetable vs. chemical), exposure to perspiration and humidity significantly affect longevity. Shell cordovan tends to last longer than standard alligator, easily reaching 5-7 years.
