Aqua Terra 2802.80.37— lug 20mm

The Omega Aqua Terra 2802.80.37 has a lug width of 20 millimeters. This dimension is measured between the inner points of the case terminals where the strap attaches via spring bars. It is essential to verify this measurement before ordering a new strap, as 20mm is a specific standard that should not be confused with the case diameter (42.20mm in this case).

The best strap depends on your lifestyle and occasions of use. For formal and professional contexts, alligator or shell cordovan paired with a steel deployant clasp represent the most sophisticated choices. For a versatile daily approach, vegetable-tanned calf leather offers balanced elegance and practicality. If you practice water activities or desire maximum informality, a satin rubber strap ensures durability and moisture resistance without aesthetic compromise.

To change the strap, you will need a spring bar tool. Position the watch with the strap facing upward, and using the spring bar tool, exert gentle inward pressure on the elastic spring bars located at the case ends. Once the spring bar is released, the old strap detaches easily. Insert the spring bars into the new strap, aligning them with the lugs, and press until you hear a click confirming proper attachment. If you prefer, you can entrust the operation to our experts at the Casati Milano atelier.

Yes, any strap with a 20mm lug width is compatible with the 2802.80.37. However, we recommend choosing straps crafted by experienced artisans who understand the proportions and construction quality required by a watch of this category. Our custom straps from Milano Straps are specifically selected and customizable to ensure visual harmony and certified durability of 18 months.

The lifespan of a leather strap depends on the material, frequency of use, and environmental conditions. Alligator and shell cordovan, thanks to their resilient natural structure, offer longevity of 3-5 years with moderate daily wear. Quality calf leather resists for 2-4 years. Continuous exposure to sun, water, and perspiration accelerates aging. All our straps benefit from an 18-month warranty, and the Casati Milano atelier offers restoration and regeneration services to further extend the life of your strap.
