Strap for Constellation Quartz 24 Brushed Stainless Steel / Gold Claws / Blue Supernova

The lug width is 18mm. This measurement corresponds to the distance between the two attachment pins on the case. It is essential to verify this before purchasing a strap, as an incompatible lug width will not fit correctly. All 18mm strap models from Milano Straps are compatible with this timepiece.

For a Constellation in yellow gold and steel, we recommend alligator (fine texture and natural patina) or vegetable-tanned calf leather (inherent softness and colour development over time). Black alligator creates continuity with the steel; warm-toned calf (tobacco, burgundy) enhances the yellow gold. Rubber or silicone are not recommended, as they detract from the jewellery-like character of the watch.

Use a dedicated spring bar tool to remove the pins. Position the watch on a soft surface, locate the metal pins at the sides of the case (visible through the holes), gently push the tool inward to compress the pin and extract it. Repeat on the other side. Insert the pins into the new strap by aligning the holes, then reinstall the pins in the case until they click into place. If you are not experienced, contact a watchmaker or Casati Milano for the service.

Yes, provided it is specifically constructed for 18mm lug width. Compatibility depends on lug width, not the watch brand. Milano Straps' artisanal straps are crafted with precise tolerances to fit perfectly with standard pins. Always verify the technical specifications before purchase.

An alligator or vegetable-tanned calf strap, if worn daily on a 24mm Constellation, typically lasts 2-4 years before showing significant wear (cracking, thinning). Durability depends on climate, frequency of wear, water exposure, and tanning quality. Casati Milano offers an 18-month warranty and can restore worn straps through professional reconditioning.
