Frequently asked questions
What is the lug width of the Omega Constellation 123.10.27.60.51.002?
The Omega Constellation 123.10.27.60.51.002 features a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 18 mm. This dimension is standard for prestigious women's wristwatches and is decisive in selecting compatible straps and bracelets. You can measure the lug width with a digital caliper by positioning it perpendicular to the lateral lugs of the case, excluding the lugs themselves.
What is the best strap for the Constellation 123.10.27.60.51.002?
The best strap depends on your personal style. For maximum formal elegance we recommend <a href="/pages/termine-glossario/alligatore">alligator</a> in brown or black with a <a href="/pages/termine-glossario/deployante">deployant clasp</a> in precious metal. For everyday versatility, vegetable-tanned <a href="/pages/termine-glossario/concia-vegetale">calf leather</a> offers a patina that ages magnificently. NATO straps in silk or rubber are ideal for those desiring practicality without sacrificing elegance.
How do you change the strap on the Constellation 123.10.27.60.51.002?
Strap replacement requires removal of the lateral pins that pass through the case lugs. Use a spring bar tool to gently push the small metal pin that secures the strap. Once extracted, the old strap comes off easily. Insert the new strap by aligning its pins into the case openings and press until you feel the locking click. If you are unsure, entrust the operation to a professional watchmaker.
Are aftermarket 18 mm straps compatible with this Omega?
Yes, any strap with an <a href="/pages/termine-glossario/misura-ansa">18 mm lug width</a> is compatible with the 123.10.27.60.51.002, provided that the pins and openings are of quality and precisely calibrated. We recommend always verifying the specifications of the chosen strap and ensuring that the seller guarantees compatibility. Our <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-18mm">18 mm straps</a> are certified compatible with this model.
How long does a leather strap last over time?
A high-quality <a href="/pages/termine-glossario/alligatore">alligator</a> or calf strap, if subjected to <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a>, can last 3-5 years of regular daily use, while developing a rich and fascinating patina. With periodic maintenance (leather hydration, avoiding excessive moisture) the lifespan can be extended. Straps crafted from premium leathers at the Casati Milano atelier include an 18-month warranty and can be renewed at our laboratory with conservative procedures.
