Strap for Constellation Quartz 25.5 Stainless Steel / Yellow Gold / Diamond / Silver

The Omega Constellation 1277.30.00 has a lug width of 20mm. This measurement refers to the distance between the two spring bars that connect the strap to the case. It is essential to choose straps with this exact tolerance to ensure stability and security.

For the Constellation 1277.30.00 we recommend alligator straps for formal occasions, vegetable-tanned calf leather for daily use and patina longevity, or cotton NATO straps for more casual settings. The choice depends on the dial and intended use.

To change the strap, you need to remove the spring bars using a dedicated spring bar tool. If you don't own the tool, we recommend having the operation performed by a professional watchmaker. Casati Milano offers change and custom personalization services.

Yes, you can use aftermarket straps provided they respect the 20mm lug width. On milanostraps.it you will find a selection of compatible straps ready for shipment, customizable with initials and stitching thread of your choice.

The lifespan of a leather strap depends on the quality of the tanning, daily use and care. An alligator or shell cordovan strap can last 3-5 years with moderate use. With vegetable tanning, the leather ages developing a characteristic patina. Casati Milano guarantees 18 months on all personalized straps.
