Strap for Constellation Quartz 27 Brushed Stainless Steel / Blue Feather

The lug width is 18 mm. This is the internal distance between the case's through-holes. You can verify it with a digital caliper positioned perpendicularly between the two holes where the strap attaches. For the 27 mm Constellation, 18 mm represents the ideal proportion between strap visibility and case readability.

Alligator is the primary choice for the 27 mm Constellation: fine grain amplifies elegance without visual weight. Vegetable-tanned calf is excellent for daily wear, as it develops a personal patina over time. Shell cordovan offers dense texture and natural lustre ideal for formal occasions, but is not recommended in high-humidity environments. For less formal use, fabric NATO or rubber remain valid options.

To change the strap, you will need a spring bar removal tool. Position the watch with the upper lug facing upward, insert the tool tip into the small hole next to the lug and gently push to compress the spring bar. The old strap will detach. Repeat for the lower lug. To install the new 18 mm strap, align the strap holes with the lugs, compress the new spring bar and ensure it is locked securely.

Yes, any strap with an 18 mm lug width is compatible. On milanostraps.it you will find customizable artisanal straps in length, initials and type of stitching thread. Make sure the strap is long enough for your wrist: a 27 mm Constellation requires slightly shorter straps than 40 mm models, typically 115–125 mm for the long side.

Durability depends on the material and usage. A fine alligator strap lasts 3–5 years with regular use and maintenance (avoid prolonged water exposure, protect from chemicals). Vegetable-tanned calf can last 2–4 years if worn daily. Shell cordovan is more resistant, potentially 5–7 years if protected from moisture. Rotating between different straps extends the life of each one, reducing wear load on a single strap.
