Frequently asked questions
What is the lug width of the Omega Constellation 123.55.27.60.55.008?
The lug width of the Constellation 123.55.27.60.55.008 is 20mm. This measurement represents the distance between the two gold lugs where the strap passes through. To verify it, measure from one lug to the other on the outer circumference of the lug using a digital caliper.
What type of strap is best suited for the Constellation 123.55.27.60.55.008?
Alligator remains the reference choice for this 27mm yellow gold case, thanks to its natural texture that does not weigh down the female wrist. Shell cordovan represents the absolute premium option, developing a unique patina within 3-6 months. Vegetable-tanned calf offers the best versatility and natural patina over time.
How do you change the strap on an Omega Constellation 123.55.27.60.55.008?
The strap is changed using a tool called a spring bar tool. Apply controlled pressure to one of the two small metal buttons (spring bars) located at the ends of the lugs, release the attachment and you can remove the old strap. Position the new strap by aligning it with the two eyelets and press until you feel the spring click into place.
Is an aftermarket strap compatible with the Omega Constellation 123.55.27.60.55.008?
Yes, provided the strap has a lug width of exactly 20mm. Our straps on milanostraps.it are developed specifically for this measurement and guarantee perfect compatibility. Always verify that the buckle and attachments are in gold or steel to maintain the jeweler-like aesthetic.
How long does a leather strap last on an Omega Constellation?
Durability depends on the type of leather and usage. Quality alligator or shell cordovan, with appropriate maintenance (avoiding excessive moisture and dirt), lasts 3-4 years of daily use. Our handcrafted straps include an 18-month warranty. Vegetable-tanned calf develops an elegant patina even after 2-3 years, improving the aesthetic over time.
