Frequently asked questions
What is the lug width of my Omega Constellation 131.25.25.60.55.002?
The lug width of the Constellation 131.25.25.60.55.002 is exactly 16mm. This dimension is standardized for all ladies' models in this collection and corresponds to the net distance between the case lugs. Any strap with this lug width will fit perfectly without forcing.
Which strap material is recommended for an Omega Constellation with mother-of-pearl dial?
Alligator remains the most suitable choice, particularly in matte black or cognac brown tones, to enhance the warmth of yellow gold and create harmony with the mother-of-pearl dial. Shell cordovan offers a sophisticated alternative with natural luster, while vegetable-tanned calf provides softness and breathability. We advise against sports materials or heavily saturated colors.
How do I change the strap on my Constellation 131.25.25.60.55.002?
Straps are changed by removing the spring bar present in the case lugs. Position the watch on a soft surface (felt cloth), use a thin and non-invasive tool (a needle or dedicated spring bar tool) to lift the metal spring bar and slide it out. Once the lugs are free, insert the new strap in the opposite direction. If you are not experienced, entrust the task to a certified watchmaker to avoid scratches on the case.
Are third-party straps really compatible with my 25mm Omega Constellation?
Yes, provided they have a lug width of 16mm. Artisanal straps in alligator, cordovan or calf with this specific lug width will fit the original lugs without issue. Always verify the measurement before purchase by consulting the technical specifications of the desired strap.
How long does an alligator or shell cordovan leather strap last on a ladies' watch like the Constellation?
An artisanal alligator or cordovan strap, with ordinary care (avoiding prolonged exposure to water and humidity), maintains structural integrity for 8-12 years. The leather ennobles during this period, developing a patina that increases its aesthetic value. Visible wear depends on frequency of use: a Constellation worn daily will require strap replacement sooner than one worn occasionally. The standard warranty on artisanal straps is 18 months.
