Strap for Constellation Quartz 27 Brushed Stainless Steel / Yellow Gold / Tahiti MOP

The Omega Constellation 123.20.27.60.57.007 has a lug width of 20mm, meaning the distance between the two attachment holes on the lugs is exactly 20 millimetres. This measurement is standard for mid-size feminine Constellation models and requires specific 20mm straps to ensure precise fitting.

For the two-tone steel/yellow gold with mother-of-pearl dial, we recommend black alligator for formal elegance, cognac brown alligator for natural colour harmony, or Italian vegetable-tanned calf for evolving patina over time. The choice should enhance the mother-of-pearl dial without competing visually.

It is a simple operation: use a small Phillips head screwdriver or a spring bar removal tool. Position the watch with the lugs facing upward, locate the attachment holes, insert the tool to release the elastic pins (spring bars), remove the old strap and insert the new one by aligning the holes. It takes just 2-3 minutes.

Yes, any 20mm strap with standard spring bars is compatible. Omega uses universal elastic pins: simply choose straps with 20mm lug width from specialized suppliers such as Milano Straps, which offers a wide catalogue in premium materials.

A high-quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with daily wear, depending on humidity, sunlight and frequency of use. Vegetable tanning ages visibly and desirably, while chrome tanning lasts longer but evolves less aesthetically. Proper maintenance (drying after rain, protection from heat) significantly extends durability.
