Frequently asked questions

What is the lug width of the Omega Aqua Terra 231.13.34.20.55.001?

The lug width is 20mm, identical for the reference 23113342055001. This dimension is specific to Omega's compact models and differs from the 22mm of the more voluminous timepieces in the collection. To verify it, remove the original strap and measure the internal distance between the two lugs.

What is the best strap for the Omega Aqua Terra 34mm?

It depends on the intended use: Mississippi alligator is ideal for formal occasions and dinners (regular grain, reduced weight). Vegetable-tanned calf is perfect for summer everyday wear with evolving patina. Shell cordovan develops unequaled chromatic depth over time. NATO is the versatile and sporty solution. Vulcanized rubber is reserved for frequent aquatic environments.

How to change the strap of the Omega Aqua Terra 231.13.34.20.55.001?

Remove the spring bar using a dedicated tool by applying gentle pressure on the small lateral button. Once the lug is freed, the spring bar will slide out smoothly. Reverse the process with the new strap, ensuring the spring bar is perfectly aligned and the strap lies symmetrically on both sides of the case.

Which aftermarket strap is compatible with the Omega Aqua Terra 231.13.34.20.55.001?

Any strap with a 20mm lug width (tolerance ±0.5mm) is compatible. Online you will find a selection of 20mm straps in alligator, calf, shell cordovan and technical materials, customizable in color, initials and stitching thread. The Casati Milano atelier also offers bespoke straps by appointment with personal leather selection.

How long does a leather strap last for the Omega Aqua Terra 34mm?

Durability depends on the material and usage regime. Alligator and calf, with proper care, guarantee 3-5 years of daily wear before requiring replacement. Shell cordovan, being more resistant, can last 5-7 years. Prolonged exposure to humidity and perspiration significantly shortens durability: for frequent aquatic environments, vulcanized rubber is preferable. Casati Milano offers an 18-month guarantee on all straps produced.
