Strap for Constellation Quartz 24 Brushed Stainless Steel / Red Gold / MOP

The lug width of the Constellation 123.20.24.60.05.001 measures exactly 20mm, the distance between the two horizontal pins. This measurement is standard across the entire Constellation family in 24mm format and requires straps specifically sized for 20mm lug width to avoid misalignment.

For the two-tone Constellation, we recommend alligator in cognac or dark brown tones, which enhance the warmth of the gold without competing visually. Shell cordovan is ideal for those seeking a patina that develops over time. For daily wear, vegetable-tanned calf offers softness and minimal bulk, while rubber is practical for humid environments.

Position the watch with the case facing down on a soft surface. Locate the spring bar pins (small metal cylinders on the sides of the case). Using a spring bar tool, gently push the pin laterally towards the inside of the case to expand the internal spring, then extract the pin. Repeat on the other side. Insert the new strap by aligning the holes with the pins, then reinsert the pins one at a time, ensuring the spring closes completely.

Absolutely. Any strap in 20mm lug width is compatible with the Constellation 123.20.24.60.05.001. We recommend verifying the total strap width at the thickest point (approximately 3-4mm to maintain proportions) and the attachment system to the pins, which must be standard. Handcrafted straps from Milano Straps are built specifically for this measurement.

A quality leather strap (alligator, cordovan, calf) worn daily with regular rotation typically lasts 3-5 years on average. Wear depends on humidity, perspiration, sun exposure, and frequency of wear. Vegetable-tanned leather develops patina more quickly but remains robust; shell cordovan is the most durable. We recommend rotating with rubber straps in humid environments to extend overall lifespan.
