Aqua Terra 2604.50.37— lug 20mm

The Omega Aqua Terra 2604.50.37 has a lug width of 20mm. This measurement represents the width of the case portion where the strap is attached. Always verify this dimension before purchasing an aftermarket strap to ensure perfect compatibility.

For a yellow gold Aqua Terra, dark brown alligator with vegetable tanning is ideal for formal occasions, offering an elegant contrast without competing with the precious metal. For more versatile use, vegetable-tanned calf leather provides softness and a patina that evolves over time, enhancing the watch's aesthetics.

Changing the strap requires a specific tool (spring bar tool) and just a few minutes. Position the watch face down, insert the spring bar tool into the lateral access hole of the lug to compress the spring, gently remove the old strap, and insert the new one while keeping the spring bar compressed. If you are unsure, contact an authorized Omega service center.

Yes, any strap with a 20mm lug width is compatible with the 2604.50.37. Artisanal straps offer greater flexibility in choosing materials (alligator, shell cordovan, calf), colors and finishes compared to the standard Omega offering, allowing customization that reflects your investment in the precious metal.

The lifespan of a leather strap depends on the material and use. Alligator and shell cordovan, when subjected to quality vegetable tanning, maintain structural integrity for 4-6 years with daily wear. Calf leather, being more delicate, requires servicing every 3-4 years. The natural aging of ennobled leather is added character, not deterioration: with proper maintenance and occasional visits to the atelier, longevity extends significantly.
