Strap for Constellation Automatic 27.5 Stainless Steel / Yellow Gold / Silver

The lug width of the Constellation 1392.30.00 is 18mm. This measurement is essential when purchasing compatible straps: an incorrect measurement would result in mechanical incompatibility. To verify, position a digital caliper between the two spring bar pins on the case back, perpendicular to the vertical axis of the watch.

For the Constellation 1392.30.00 we recommend polished alligator for gold/steel examples: the fine grain enhances the reflections of the precious case, creating a natural aesthetic harmony. Alternatively, shell cordovan represents a distinctive and sophisticated option, ideal for a patina that evolves over time. For the more sporty versions, satin FKM rubber ensures practicality without compromising elegance.

The change is made by acting on the spring bars that connect the strap to the case. Use a dedicated tool – a lug width tool or a small flat screwdriver – to compress the small internal hook of the spring bar, releasing the old strap. Then insert the new strap by aligning the lug holes with the spring bars, pushing until you feel the closure click. Proceed with caution to avoid scratches on the case.

Aftermarket artisanal straps offer greater customization compared to the integrated Manhattan bracelet: choice of leather, colors, stitching and buckle or <a href="/pages/termine-glossario/deployante">deployante</a>. Always verify compatibility by measuring the width before purchase.

The durability depends on the quality of the leather, daily use and maintenance. A well-crafted alligator or calf leather strap typically lasts 3-5 years of regular use before showing obvious signs of wear. Vegetable tanning evolves gracefully, developing a beautiful patina. To extend longevity, avoid prolonged exposure to direct sunlight and excessive humidity, and apply leather conditioner every 12-18 months.
