Frequently asked questions
What is the lug width of the Omega Aqua Terra 231.53.42.22.02.001?
The lug width of the Omega Aqua Terra 231.53.42.22.02.001 is 20 millimeters. This width is specific to this timepiece and represents the compatibility standard for any aftermarket strap. For verification, measure perpendicularly with a digital caliper from the inner edge of one lug to the other, in the area where it connects to the case.
What strap is recommended for the Aqua Terra in rose gold?
For the 231.53.42.22.02.001 in rose gold, we recommend American alligator with fine grain (dark brown or cognac) or black shell cordovan for formal occasions. Vegetable-tanned calf leather represents an elegant and more accessible alternative, developing a patina that evolves over time in harmony with the precious metal of the case.
How do you change the strap on the Omega Aqua Terra 231.53.42.22.02.001?
The Aqua Terra 231.53.42.22.02.001 is equipped with fixed lugs not welded to the case. Use a spring bar tool (a specific instrument with two opposing tips) to gently compress the internal elastic pin beneath the lugs: once loosened, the previous strap disengages easily. Insert the new strap by aligning the lugs with the corresponding holes and release the spring bar. For convenience, contact Casati Milano for professional strap changing.
Are there quality aftermarket straps available for the 231.53.42.22.02.001?
Yes, 20mm straps compatible with the Aqua Terra 231.53.42.22.02.001 are available online. On milanostraps.it you will find a selection of alligator, calf, and exotic leather straps ready for shipment, all customizable in length, initials, and thread type. For a completely bespoke project, the Casati Milano atelier creates made-to-measure straps with personal consultation.
How long does a leather strap last on a watch with 100m water resistance?
A quality leather strap with vegetable tanning, worn daily, maintains structural integrity for 3-5 years. The water resistance (100m) of your 231.53.42.22.02.001 allows for quick rinsing with wet hands, but avoid prolonged immersion. To extend the life of your strap, use a second strap during periods of intense humidity (sea, pool) and periodically apply protective balm to the tannin.
