Frequently asked questions
What is the lug width of the Omega Constellation 131.20.36.60.08.001?
The lug width of the Constellation 131.20.36.60.08.001 is 23 millimeters. This is the internal space between the two lugs of the case where the strap is inserted. It is a fundamental measurement to ensure compatibility with any aftermarket strap.
Which strap is most suitable for the Omega Constellation 131.20.36.60.08.001?
For the Constellation 131.20.36.60.08.001, alligator or shell cordovan straps represent the most refined and durable choices. Alligator offers traditional elegance with a captivating natural grain, while cordovan provides extraordinary resistance and a deep patina over time. Vegetable-tanned calf is an ethical and modern alternative that maintains high quality standards. The choice depends on your personal style and predominant use context.
How do you change the strap on an Omega Constellation?
To change the strap, you need to remove the pins or spring bars that connect the strap to the case lugs. Use a dedicated tool or a small screwdriver to gently lever on the pins, freeing the old strap. Insert the new strap by aligning the holes with the lugs and reinsert the pins until you feel the click of closure. Ensure the pins are fully in position to prevent the strap from detaching during use.
Which aftermarket straps are compatible with the 131.20.36.60.08.001?
All straps with a lug width of 23 millimeters are compatible with this Omega Constellation. Milanostraps offers a curated selection of straps in various materials and colors, all customizable in size, initials, and stitching thread. It is important to always verify the lug width before purchase to avoid incompatibilities.
How long does a leather strap last on a watch like the Constellation?
The lifespan of a leather strap depends on the material and frequency of use. A high-quality artisanal alligator or shell cordovan strap can last from 5 to 10 years with moderate daily use, while developing a unique and fascinating patina. A vegetable-tanned calf strap has a similar lifespan but tends to show signs of wear more visibly, a characteristic many appreciate as part of natural aging. The Casati Milano atelier provides an 18-month warranty on made-to-measure straps, covering manufacturing defects and workmanship faults.
