Strap for Constellation Manhattan 25 Quartz Stainless Steel - Sedna Gold - Diamond / Lilac Meteorite

The lug width is 14mm. This is a specific measurement for the modern feminine Constellation model. To verify it, measure the distance between the internal attachment points of the case with a digital caliper. This measurement is not standard, so straps must be selected carefully for this dimension.

Natural American alligator (cognac or burgundy tones) is the most refined choice, as the open grain and warmth of the leather enhance the rose gold of Sedna. Elegant alternatives: vegetable-tanned calf leather finished traditionally (developing natural patina) or Japanese shell cordovan (compact leather with progressive lustre). For daily versatility, a grey pearl organic cotton NATO allows quick changes while maintaining aesthetic coherence.

The Constellation 131.25.25.60.99.001 uses spring bars or bayonet attachments. Use a spring bar remover (a small tool included with the finest artisanal straps) to compress the internal pin and remove the old strap. Position the new strap by aligning the slots with the case lugs, then reinsert the spring bar until you hear the locking click. Avoid hammers or screwdrivers that could damage the gilt lugs.

Any strap with a 14mm lug width is compatible. On milanostraps.it you will find the collection dedicated to 14mm straps, selected for construction quality and certified raw materials. Ensure the strap features suitable spring bars (typically 14mm in thickness) and that the slots do not rub against the gilt lugs during wrist articulation.

A naturally tanned alligator or vegetable-tanned calf strap with proper care lasts 3-5 years in daily wear, developing patina and progressive adaptation to the wrist. Shell cordovan extends this lifespan to 7-8 years thanks to the material's compactness. Wear is predictable: thinning of the slot area, possible thread detachment, leather aging. Atelier Casati Milano offers an 18-month warranty and professional revision/repair beyond this period.
