Frequently asked questions
What is the lug width of the Omega Constellation 123.25.24.60.55.010?
The Omega Constellation 123.25.24.60.55.010 features a lug width of 16 millimetres. This is the exact distance between the two lugs on the case where you attach the strap. It is essential to verify this measurement before ordering an aftermarket strap, as watches from the same brand can have lugs of varying widths.
Which strap is best suited for the 24mm Constellation with mother-of-pearl dial?
For the 123.25.24.60.55.010, we recommend vegetable-tanned alligator in dark blue or black: the rippled texture of the grain and dark colour create an elegant contrast with the luminous mother-of-pearl, without competing visually. Tobacco-brown calf leather is ideal if you prefer tonal warmth. For summer wear, beige cotton NATO maintains freshness and facilitates easy changes.
How do you change the strap on the Omega Constellation 123.25.24.60.55.010?
The strap is changed by removing the spring bars (the metal pins) that connect the strap to the case lugs. Use a strap removal tool or specialised tool: insert the sharp tip into the holes located at the sides of the spring bars to extract the pin from bottom to top. Once the old strap is removed, thread the new strap through the spring bars and reinsert the pins from top to bottom until they click into position. A simple operation requiring only basic tools.
Is the strap on the Constellation 123.25.24.60.55.010 compatible with other Omega models?
Only partially. Although many ladies' Omega models feature 16mm lugs, compatibility depends not only on lug width but also on case shape and thickness. The Constellation 123.25.24.60.55.010 was designed with a slim case: straps made for other Omega families with different proportions may not fit correctly either aesthetically or functionally. We recommend always verifying specifications with your supplier.
How long does a leather strap last on an Omega Constellation?
A quality leather strap (alligator or calf with vegetable tanning) lasts on average 3–5 years if worn daily, 5–7 years with occasional use. Longevity depends on exposure to external elements (sun, moisture, perspiration), tanning quality and regular care (gentle cleaning, protection from prolonged water exposure). A shell cordovan strap lasts longer (up to 8–10 years) thanks to the natural density of the material. Periodic replacement is recommended to maintain the watch's aesthetic value.
