The lug width of the Constellation 123.50.27.20.58.001 is 20mm. This dimension is specific to the ladies' models in the collection and represents the internal distance between the two lugs of the case. Accurate measurement of this internal dimension is essential to ensure complete strap compatibility.

For the Constellation 123.50.27.20.58.001 in yellow gold, an alligator strap with vegetable tanning in Havana or medium brown tones represents the ideal aesthetic choice. It creates tonal harmony with the sunburst dial and ages gracefully over time. Valid alternatives include Italian calf with preserved grain and shell cordovan for those seeking natural patina development.

Changing the strap on a Constellation requires a spring bar tool or equivalent device. Position the watch with the lugs facing upward, insert the tool into the small slot beneath the lug to compress the internal spring mechanism, then gently extract the pin. Repeat for the opposite lug. The operation requires precision to avoid case damage. If inexperienced, consult a professional.

Yes, the Constellation 123.50.27.20.58.001 accepts any strap with a 20mm lug width. Aftermarket straps offer aesthetic versatility and personalisation options compared to the original strap. Compatibility is guaranteed by the lug width dimension, provided the strap is manufactured to appropriate quality standards.

A fine leather strap (alligator, calf, shell cordovan) on an Omega ladies' Constellation typically lasts 3-5 years with moderate wear. Longevity depends on the tanning method, frequency of use, exposure to moisture and maintenance. Vegetable tanning develops patina whilst maintaining structure. Avoiding prolonged contact with water, intense heat and frequent friction extends strap lifespan significantly.
