Omega
Aqua Terra 220.55.34.20.60.002— lug 16mm

The lug width is 16mm. This is the distance between the case lugs on the 34mm case. This specification is guaranteed by the Omega certificate and cannot be modified. Any strap to be worn must respect this measurement exactly to ensure secure attachment and balanced aesthetics.

Black alligator or dark brown vegetable-tanned calf represent the ideal choices. Alligator creates an elegant chromatic contrast with the Canopus Gold, emphasizing formal sophistication. Vegetable-tanned calf develops a patina over time that dialogues beautifully with the champagne tone of the gold. Both are available with white gold deployante for material coherence.

The procedure requires a specific tool called a spring bar tool. Position the watch on a soft surface to protect it. Locate the protruding pin on the inner side of the case: insert the tool into the side slot and apply gentle pressure to compress the pin, then slide the strap out. Reverse the procedure for the new strap. If you are uncertain, Casati Milano offers the service by appointment.

Yes, provided the lug width is exactly 16mm. Many high-quality artisanal aftermarket straps are perfectly compatible, often offering customizations superior to the original Omega strap. Always verify that the manufacturer specifies 16mm and that the material (alligator, calf, rubber) is not toxic or aggressive toward the Canopus Gold.

A calf strap made with vegetable tanning has a lifespan of 3-5 years with daily wear, depending on washing frequency and humidity exposure. Alligator, being more robust, guarantees 5-7 years. The patina that forms on the leather is natural and desirable: it imparts character and authenticity. Casati Milano offers 18-month warranty and post-wear regeneration services.
