Strap for Constellation Quartz 22.5 My Choice Stainless Steel / Diamond / Blue MOP

The lug width of the Constellation 1566.66.00 is 14 millimetres. This measurement represents the distance between the two lateral lugs of the case and determines compatibility with any watch strap. You can verify this dimension manually by positioning a digital calliper perpendicularly between the inner points of the lugs, excluding any lateral ornaments.

For the Constellation 1566.66.00, alligator leather with traditional tanning represents the most stylistically coherent choice, thanks to its regular grain that echoes the geometric rigour of the griffes. Quality alternatives include vegetable-tanned calf leather for a more organic appearance, shell cordovan for exceptional chromatic depth, or cotton NATO fabric for sportier contexts. Medium brown or black tonality is recommended given the watch's blue dial.

The Constellation 1566.66.00, like most dress watches, features fixed lugs. Changing the strap requires extraction of the pins connecting the lugs to the case. Using a dedicated tool (spring bar tool), you push the small retaining pin inward, allowing extraction of the spring bar underneath. Once the lugs are free, the new strap can be fitted following the reverse procedure. This operation should be performed with care to avoid scratching the case.

Absolutely. Any strap with a 14mm lug width is compatible with the Constellation 1566.66.00, regardless of the manufacturer's brand. High-quality artisanal straps often represent a superior alternative to official Omega OEM straps, offering a wider choice of materials, customised construction, and better value for money. Compatibility depends solely on lug width, not on brand.

The lifespan of a 14mm leather strap depends on the material and usage. A quality artisanal alligator strap, with natural tanning, can last 5-8 years of regular wear before requiring replacement, developing a fascinating patina over time. Vegetable-tanned calf leather presents a similar lifespan, whilst shell cordovan, being more durable, can exceed 10 years. Continuous exposure to moisture, perspiration and sunlight accelerates ageing. Periodic maintenance with specific conditioning creams significantly extends strap longevity.
