Omega
Aqua Terra 2504.50.00— lug 20mm

The lug width of the 2504.50.00 is 20mm, measured between the centers of the spring bar attachments on the case. This dimension has been standard for Omega since the Seamaster model of the 1970s and remains unchanged in current Aqua Terra family references. Always verify that the strap you purchase is explicitly compatible with 20mm to avoid misalignment.

It depends on your use: dark brown alligator is ideal for those who alternate formal and casual contexts, as it enhances the dial elegance without weighing it down. Vegetable-tanned calf is perfect for those who want a patina that evolves over time. Shell cordovan offers extreme durability and a lustre that increases with the years. For sports use, high-density polyamide NATO and vulcanized rubber ensure practicality. All these materials are available in 20mm on milanostraps.it.

The Omega Aqua Terra 2504.50.00 uses standard spring bars. Obtain a spring bar tool (available in watchmaker tool kits), position the flat tip of the tool under the spring to decompress it, extract the bar from the first end, then repeat on the other side. Insert the new spring bars into the strap, then insert them into the case lugs. If you prefer not to do it yourself, Casati Milano offers replacement service during atelier consultations.

Yes, as long as they are compatible with the 20mm lug width. Quality aftermarket straps guarantee aesthetic variety and lower costs compared to original Omega bracelets, while maintaining full technical compatibility. Milano Straps offers a selection of 20mm straps from specialized artisans, with quality guarantee and customization options. The important thing is to choose reliable suppliers that respect construction tolerances.

Durability depends on the material and use. An alligator or vegetable-tanned calf, worn regularly with minimal care (periodic cleaning and treatment with specific creams), typically lasts 3-5 years before requiring replacement. Shell cordovan is more resistant and can exceed 7-8 years. Rubber straps maintain functionality longer but can yellow or degrade after 4-6 years of intense sun exposure. Polyamide NATO straps are practically eternal if washed periodically. Milano Straps offers an 18-month warranty on all straps made by the Casati Milano atelier.
