Strap for Constellation Co-Axial 27 Brushed Stainless Steel / Diamond / MOP Stars

The Omega Constellation 123.15.27.20.05.001 features a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 20mm, a typical size for ladies' and midsize models in the Constellation collection. This dimension requires specific straps that are not interchangeable with 18mm or 22mm sizes.

To enhance the geometric elegance of this model, we recommend <a href="/pages/termine-glossario/alligatore">alligator</a> leather in grey or navy blue tones, or black calf leather for a formal contrast. Alternatively, <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> leather with vegetable tanning develops a natural patina that enhances the character of the watch over time.

Strap replacement is performed using spring bars positioned at the ends of the case. With a small dedicated tool, depress the side springs, remove the old strap, and position the new one, ensuring that the terminals enter correctly into the attachments. If unfamiliar with the process, we recommend contacting a qualified watchmaker or our Casati Milano atelier.

Absolutely yes. Aftermarket 20mm straps are fully compatible with the Constellation 123.15.27.20.05.001, provided they respect the lug width and case height. Milano Straps offers artisanal high-quality leather straps with customizable <a href="/pages/termine-glossario/deployante">deployant clasps</a> in color, initials, and stitching thread.

A high-quality natural leather strap, subject to regular maintenance (avoiding prolonged moisture and acidic sweat), maintains a lifespan of approximately 3-5 years. With <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a>, the material develops a beautiful patina that improves over time. Milano Straps straps come with an 18-month warranty, with the possibility of regeneration at Casati Milano.
