The Aqua Terra 220.12.38.20.03.002 (aka: 22012382003002), seen from the bench

The Omega Seamaster Aqua Terra 150M Master Chronometer 38 ref. 220.12.38.20.03.002 represents the mature evolution of the Aqua Terra collection, the urban branch of the historic Seamaster line established in 1948. This 38mm stainless steel case features a blue "Shades of Blue" dial with dynamic texture, rated to 150 meters water resistance. Powered by the Master Chronometer caliber 8800 with co-axial escapement and 60-hour power reserve, this automatic watch resists magnetism up to 15,000 Gauss. The 19mm lug width is a non-negotiable specification for this model.

Frequently asked questions

What is the lug width of the Omega Aqua Terra 220.12.38.20.03.002?

The lug width is 19mm. This measurement is specific to this reference and allows the use of compatible 19mm straps. To verify it, measure with a digital caliper the distance between the inside of the two lugs at the point closest to the case.

Which strap is most suitable for the Omega Aqua Terra 220.12.38.20.03.002?

Black alligator or cognac alligator are the most natural choices, thanks to their regular texture and aesthetic compatibility with the satin case. Alternatively, vegetable-tanned calf leather for those who desire natural patina over time, or technical NATO strap for sporty use and versatility.

How do you change the strap on the Omega Aqua Terra 220.12.38.20.03.002?

The operation requires a spring bar tool or the intervention of a watchmaker. The elastic pins that bind the strap to the case must be gently compressed to remove the old strap and insert the new one. It is advisable to entrust professionals to avoid damage to the case.

Is an aftermarket 19mm strap compatible with my Omega Aqua Terra 220.12.38.20.03.002?

Yes, any strap with a 19mm lug width is mechanically compatible. However, it is essential to verify that the strap has been constructed with the correct internal width to adhere perfectly to the lugs without lateral play.

How long does a leather strap last on a watch like the Omega Aqua Terra?

A high-quality alligator or calf strap has an average lifespan of 3-5 years with regular use, depending on exposure to humidity and sweat. Vegetable tanning tends to age more visibly but maintains its structure longer. A rubber strap can last 5-10 years. Casati Milano guarantees all straps for 18 months.
