Strap for Constellation Quartz 24 Polished Stainless Steel / Yellow Gold / MOP

The lug width of the Omega Constellation 123.20.24.60.55.004 is exactly 20 mm. This measurement represents the distance between the strap attachment pins on the case and is not interchangeable with standard sizes such as 18 mm or 22 mm. It is essential to verify this measurement before purchasing a replacement strap.

For the Constellation 123.20.24.60.55.004 we recommend straps in black or dark brown alligator, which enhance the contrast with the yellow gold case. Vegetable-tanned calf leather in cognac or tamarind tones is ideal for everyday wear, while shell cordovan offers a patina that evolves over time. FKM rubber is perfect for summer contexts. On milanostraps.it you will find the complete selection of 20mm straps compatible with this model.

To change the strap, you need a spring bar tool (a specific tool for the pins). Position the tool in the small slot under the attachment pin, apply gentle pressure to retract the internal spring and slide the pin out of its housing. Repeat on the other side. Be careful not to scratch the case during the operation. If unsure, contact an authorized service center or the Casati Milano atelier.

Absolutely yes. Many owners of the Constellation 123.20.24.60.55.004 prefer artisanal quality straps to adapt the timepiece to different contexts of use. A quality leather strap with 20mm lug width ensures technical and functional compatibility. It is important to choose noble leathers – alligator, calf, shell cordovan – that respect the elegance of the case.

The lifespan of a leather strap depends on the material and usage. A superior quality alligator strap lasts an average of 3-5 years with daily use. Vegetable-tanned calf leather tends to show signs of wear after 2-4 years, but acquires a desired patina. Shell cordovan is more resistant and can last 5-7 years. Casati Milano guarantees its artisanal straps for 18 months and offers regeneration services to extend their useful life.
