Strap for Constellation Manhattan 28 Quartz Stainless Steel / Sedna Gold / MOP

The Omega Constellation 131.20.28.60.55.001 is equipped with a lug width of 16 millimetres. This measurement is specific to this model and is the standard for Constellation watches with a 28mm diameter. You can manually verify compatibility by measuring the distance between the two lugs – the lateral attachments of the case – where the strap is inserted.

For the Constellation 131.20.28.60.55.001, we recommend straps in natural alligator leather to enhance the sophistication of the Sedna Gold, vegetable-tanned calf leather for daily versatility, or shell cordovan for those seeking durability and patina development over time. The mother-of-pearl dial particularly benefits from straps with a subtle grain: avoid overly textured finishes that could compete visually with the iridescence of the case. The Casati Milano atelier creates custom straps personalizable in colour, leather type, and length.

To change the strap on your Omega Constellation 131.20.28.60.55.001, you will need a spring bar removal tool. Position the watch with the lugs facing towards you, locate the small hole in the attachments, gently insert the tool to compress the internal spring and slide the old strap outward. Repeat the operation on the other side. Insert the new 16mm strap in the opposite direction, ensuring the spring bars are securely fastened. If you are inexperienced, consulting a professional watchmaker or contacting Casati Milano for installation is always recommended.

All straps with a lug width of 16 millimetres are compatible with the Omega Constellation 131.20.28.60.55.001. On milanostraps.it you will find a selection of artisanal 16mm straps ready for shipment, crafted in premium leathers and customizable in length, stitching and colour. It is also possible to order completely bespoke straps from the Casati Milano atelier, with personal selection of leather and finishes executed according to your aesthetic preferences.

The lifespan of a leather strap depends on the quality of the material, frequency of use and environmental conditions. A premium alligator or shell cordovan strap with vegetable tanning can last from 3 to 5 years with moderate daily use, developing an elegant patina over time. Vegetable-tanned calf leather has a similar lifespan. Factors such as humidity, heat and sun exposure accelerate ageing. The Casati Milano atelier offers an 18-month guarantee on all straps produced and provides advice on maintenance and cleaning to extend the life of your strap.
