Frequently asked questions

What is the exact lug width of the Omega Aqua Terra 220.58.38.20.99.006?

The Omega Aqua Terra 220.58.38.20.99.006 has a lug width of 19mm. This dimension corresponds to the width measured between the two inner shoulders of the case. It is important to respect this specification to avoid lateral oscillations of the strap during use.

Which straps are compatible with reference 220.58.38.20.99.006?

Only straps with a 19mm lug width are compatible with this model. Suitable options include alligator, vegetable calf, NATO fabric, FKM rubber, and shell cordovan. You can find the complete collection of 19mm straps on milanostraps.it, available in numerous colours and finishes.

How do you replace the Omega Aqua Terra strap without damaging the case?

To change the strap on a wristwatch, you need to use a specialized spring bar removal tool. Position the flat tip in the space between the lug and the strap, gently pushing upward to compress the internal spring bar. With the spring bar released, remove the strap with your other hand. Reverse the procedure for installing the new strap. If you prefer to avoid the risk of damage, Casati Milano offers a replacement service by appointment.

Is the Aqua Terra strap 220.58.38.20.99.006 made of original leather or rubber?

The Omega Aqua Terra 220.58.38.20.99.006 is supplied with a natural alligator strap and Omega buckle. However, thanks to the 19mm lug width, it is easily interchangeable with artisanal aftermarket straps in leather, rubber, or fabric to suit different occasions of use.

How long does a natural leather strap last on an Omega Aqua Terra?

A high-quality artisanal leather strap, with moderate use and proper maintenance, typically lasts 3-5 years. Longevity depends on the frequency of wear, exposure to moisture, and care of the material. Casati Milano straps include an 18-month warranty and can be regenerated or replaced at reasonable cost through the after-sales service.
