Strap for Constellation Quartz 25.5 '95 Stainless Steel / Yellow Gold / Champagne

The lug width of the Constellation 1272.10.00 is 14mm. This measurement represents the distance between the two metal pins that attach the strap to the lateral lugs of the case. To verify the measurement with precision, use a digital caliper or a millimeter ruler, positioning the measurement directly between the lug holes. It is an important standard for choosing compatible aftermarket straps without risk of slippage or friction.

For a bicolour gold-steel Constellation, we recommend alligator in dark brown or black tones, which pairs elegantly with the two metals of the case. A sophisticated alternative is vegetable-tanned calf leather in cognac, which develops a patina over time and maintains the warmth of the gold. If you prefer a more casual style, a dark blue or green NATO or Perlon offers lightness without sacrificing aesthetic coherence. Avoid overly light shades, which could further diminish the compact design.

The 1272.10.00 features a bracelet integrated into the case, so changing the strap is not as straightforward as with modern watches. If you have just the case, use a spring bar tool to remove the pins from the lugs and replace the strap. If the bracelet is still mounted, consult a professional watchmaker to avoid damaging the iconic griffes or bicolour finishing. Milano Straps recommends the Casati Milano atelier for precision work.

All straps with 14mm lug width are compatible: alligator, calf, shell cordovan, vegetable-tanned leather, NATO, Perlon and rubber. Always verify that the pins on your straps are in good condition and fit into the lugs without forcing. Many Constellation owners choose to keep the original bracelet and alternate one or two straps for different occasions, leveraging the narrow lug width for greater aesthetic versatility.

A quality handcrafted leather strap, whether vegetable-tanned or alligator, typically lasts 3-5 years with daily wear. The lifespan depends on exposure to moisture, sweat and frequency of wear. Vegetable-tanned leather ages and develops a natural patina while maintaining structural integrity over the long term. To extend the life of your strap, avoid prolonged water immersion (the Constellation reaches only 30 meters) and clean periodically with a soft brush. Casati Milano offers an 18-month warranty on all straps.
