Strap for Constellation Co-axial 35 Yellow Gold / Diamond / Diamond Supernova

The Omega Constellation 123.55.35.20.55.001 has a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 18 millimetres. This dimension is standard for the 35mm case model and is readily compatible with most handcrafted straps available on the market.

For a Constellation in 18-carat yellow gold, we recommend chocolate brown <a href="/pages/termine-glossario/alligatore">alligator</a> or vintage calf with soft patina. Alligator emphasizes the formal elegance of the precious case, while vegetable-tanned calf offers a more casual character with natural ageing. Avoid sports straps – the tone of gold demands materials that breathe luxury, not functionality.

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> is measured by determining the internal space between the two metal protrusions (the "spring bar lugs") of the case, from inside to inside, using a digital calliper or soft ruler. For the 123.55.35.20.55.001, the value is always 18mm. Verifying the measurement before ordering is good practice, even though the specification does not change.

Yes, absolutely. The 123.55.35.20.55.001 supports any standard 18mm <a href="/pages/termine-glossario/deployante">deployante</a> or pin buckle. The procedure requires removal of the original spring bars (with a dedicated tool) and insertion of new ones into the purchased strap. We recommend assistance from an optical shop or watchmaker if you are not familiar with the operation.

A quality leather strap, crafted with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> like ours, offers an average lifespan of 2–4 years with daily use and ordinary maintenance (light cleaning, drying after exposure to moisture). The yellow gold of the Constellation, not subject to corrosion from oxidizing metals, naturally protects the strap from accelerated degradation. Mindful care easily extends its life beyond four years.
