Frequently asked questions
What is the lug width of the Omega Constellation 123.25.24.60.52.001?
The lug width is 20mm. This measurement is obtained by measuring the distance between the two attachment holes on the case where the strap attaches. It is essential to know this value when purchasing compatible aftermarket straps.
Which strap is most suitable for the Omega Constellation 24mm in rose gold and steel?
For this two-tone configuration, medium brown alligator represents the ideal choice: it creates chromatic continuity with the rose gold while maintaining elegance without compromise. Alternatively, vegetable-tanned calf in cognac tone pairs magnificently with the case materials, enhancing the two-tone sophistication.
How do you change the strap on an Omega Constellation?
The change is made with a spring bar tool (pry bar): insert the tip into the lateral slot at the base of the case, apply gentle pressure to release the attachment pin, slide off the old strap, insert the new one by aligning the holes with the pins, then secure by pressing until it clicks. Avoid sharp blows; the movement should be fluid.
Is a 20mm aftermarket strap completely compatible with the 123.25.24.60.52.001?
Yes, provided it is manufactured to 20mm standard. However, the quality of the artisanal strap significantly affects comfort and longevity. Milano Straps offers compatible straps in premium leather (alligator, cordovan, calf) with correct pins and finishes that respect the proportions of the Constellation.
How long does a leather strap last on a 24mm Omega Constellation?
A premium leather strap (alligator, shell cordovan) lasts 3-5 years with daily use, developing patina over time. Chrome or vegetable-tanned calf tends to last 2-4 years. Durability depends on usage, sun exposure, humidity, and care. A well-maintained artisanal strap can be restored through re-stitching and leather reconditioning.
