Frequently asked questions

What is the lug width of the Omega Constellation 123.50.38.22.02.001?

The Omega Constellation 123.50.38.22.02.001 is fitted with a 20mm lug width. This measurement is essential for selecting a compatible strap. Always verify on the case or in the official documentation before making a purchase.

What is the best strap for the Constellation 123.50.38.22.02.001 in rose gold?

For a Constellation in red gold, we recommend noble leathers such as genuine alligator or shell cordovan in dark brown, cognac, or burgundy tones. Alligator amplifies the luxurious character of the case, while cordovan develops a captivating patina over time. Alternatively, aged English calfskin with vegetable tanning imparts understated elegance.

How do I change the strap on the Omega Constellation 123.50.38.22.02.001?

The procedure requires a dedicated spring bar tool. Position the watch with the lugs facing upward, insert the tool under the spring bar lug, apply gentle pressure and release the pin. Repeat on the other side. Insert the new strap by aligning the lug holes and ensure the pins click into position. If you are not experienced, entrust the task to an Omega service center.

Can I mount an aftermarket strap on the Constellation 123.50.38.22.02.001?

Yes, absolutely. The 20mm lug width is compatible with any strap of the same size. Custom artisanal straps offer significant aesthetic advantages: superior leather quality, thickness and finish calibrated to your preference, choice of buckle and stitching. Milano Straps offers compatible straps in various leathers and shades.

How long does a leather strap last on the Omega Constellation?

Durability depends on leather quality and usage. Artisanal-grade alligator or shell cordovan guarantees 4-7 years of daily wear before the first replacement. With regular maintenance (cleaning with a soft cloth, protection from excessive moisture), lifespan extends. Casati Milano straps come with an 18-month warranty and can be refurbished or replaced at the atelier.
