Strap for Constellation Manhattan 28 Quartz Sedna Gold / MOP

The lug width of the 131.50.28.60.55.001 model is 14mm. This is the standard width of the pins on which the strap rests. To verify it, measure the distance between the two metal pins (lugs) inserted in the spring bar of the case. Precise measurement ensures correct fitting of aftermarket straps.

Alligator in cognac or medium brown tones is the most elegant and durable choice, with regular grain that beautifully contrasts with Sedna Gold. Bordeaux shell cordovan offers exceptional natural patina and progressive lustre. For maximum formality, choose black vegetable-tanned calf. A grey tortoiseshell silk NATO allows a more casual contemporary reinterpretation.

To change the strap, use a dedicated spring bar tool to gently compress the internal spring of the pin and release the strap from the case lug. Carefully extract the pins from the lugs of the old strap and insert them into the passants of the new strap, ensuring the spring clicks correctly into the case holes. Gentle but firm pressure guarantees stable attachment without damage.

Yes, all 14mm straps are compatible with the 131.50.28.60.55.001. On milanostraps.it you will find a selection of 14mm straps ready for shipment, customizable in sizes, initials and thread colour, plus consultation for colour choices and materials.

Durability depends on the material and usage: vegetable-tanned alligator guarantees 5-7 years with ordinary maintenance and moderate UV exposure. Shell cordovan, more resilient, can last 7-10 years developing a characteristic patina. Regenerated leather has a shorter life cycle, 2-4 years. Atelier Casati Milano provides an 18-month warranty and offers restoration services to extend the strap's life.
