Constellation 1920.18.00— lug 18mm

The Omega Constellation 1920.18.00 features a lug width of 18 mm. This dimension corresponds to the space between the two attachment points of the strap to the case and must be verified with precision to ensure mechanical compatibility and aesthetic harmony.

For this yellow gold case, dark brown alligator or shell cordovan represent the most sophisticated choices, as their natural grain dialogues elegantly with the case geometry without competing. A vegetable-tanned calf leather is ideal for those seeking sustainable modernity, while a vulcanized rubber strap offers versatility for everyday wear.

To change the strap, you must use a specific tool to remove the spring bars that connect the strap to the case lugs. This task requires precision and awareness: the Casati Milano atelier offers this service as part of bespoke consultation to ensure that the new 18 mm strap is positioned correctly without damaging the case.

Any strap equipped with an 18 mm lug width is mechanically compatible. Milano Straps offers a curated selection of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-18mm">18mm straps</a> in alligator, shell cordovan, calf and rubber, selected considering the stylistic identity of the Constellation to guarantee aesthetic coherence.

Durability depends on the material and usage. An alligator or shell cordovan, with proper maintenance and alternation with other straps, maintains structural integrity for 3-5 years. A vegetable-tanned calf, more sensitive to moisture, has similar durability if protected. Milano Straps guarantees 18 months on all custom-made straps realized at the Casati Milano atelier.
