The Aqua Terra Worldtimer is one of those Omegas that quietly flexes. It looks dressy at a glance, then you notice the city ring and that laser-engraved globe in the middle, and you remember it is basically a travel complication disguised as a clean everyday watch.
If you are wearing the Seamaster Aqua Terra “Worldtimer” 43mm (2017 to now), especially references 220.10.43.22.03.001 / 220.10.43.22.03.002 and 220.12.43.22.03.001, you already know the vibe: sporty enough to take abuse, refined enough to not look out of place with a jacket. The strap you choose should match that split personality.
Strap size and fit guide (read this before you order)
This model is 43mm, and Omega gave it a 21mm lug width. That 21mm matters more than people expect because it is the easiest place to make an annoying mistake. A 20mm will look slightly skinny and can shift, and a 22mm is simply not happening without forcing it.
When you’re on a Helvetus product page, you must select the 21mm option. That is the correct size for the Worldtimer case. If you pick 20mm by habit, it will not sit right. If you are buying specifically for the Worldtimer, just lock in this rule: Worldtimer 43mm equals 21mm.
The best strap choices for the Aqua Terra Worldtimer 43mm
If you want the watch to feel more “Worldtimer” and less “office Aqua Terra,” rubber is the easy win. It makes the 43mm case wear more relaxed, and it fits the modern Omega design language perfectly.
Blue and white, for the most natural match
This one just makes sense on the blue Worldtimer dials. The white adds contrast that plays nicely with the city ring and the bright details, without turning the watch into something loud. It feels like a holiday strap, but still clean enough for daily wear.
Here’s the one I’d pick first if you want a strap that looks like it could have been offered by Omega from the start:
Blue/White Omega Seamaster Aqua Terra Rubber Strap
Full blue, when you want the watch to look sharper and a bit more grown up
A full blue strap leans into the watch’s elegant side. It makes the Worldtimer look more “put together,” especially when you are wearing darker clothing. On a 43mm case, a single strong color can actually make things look more streamlined, not bigger.
If your Worldtimer is your daily, this is the safe, always-right option:
Full Blue Omega Seamaster Aqua Terra Rubber Strap
Light blue, for a more modern, fresh look
Light blue changes the personality of the watch. The Worldtimer can sometimes read a bit serious because of the dial complexity, and this instantly makes it feel more playful and current. Perfect for casual wear, warm weather, or if you are just bored of the usual navy and black rotation.
This one is surprisingly wearable if you keep the rest of your look simple:
Light Blue Omega Seamaster Aqua Terra Rubber Strap

It is the easiest way to find something that matches your exact dial tone and how you actually wear the watch day to day.
Buying the right strap from Helvetus (without overthinking it)
The main thing with the Aqua Terra Worldtimer is getting a strap that suits the proportions of the 43mm case and sits cleanly between the lugs. The Helvetus straps in the Aqua Terra collection are made specifically with this model in mind, so you are not doing the “close enough” approach that often looks off on a watch this detailed.
Just remember the practical part: pick the strap you like, and select 21mm on the product page. That single step prevents most ordering mistakes.
Closing thoughts
The Worldtimer is a watch people buy because they appreciate details, so it deserves a strap that does not feel like an afterthought. A good rubber strap makes it more comfortable, more wearable, and honestly more fun, while still keeping that Omega polish.
And if you like the quiet reassurance side of things, Helvetus backs these straps with a lifetime warranty, ships them free worldwide, and you do not get hit with import costs. It is also not some tiny unknown operation, either. Helvetus is trusted by 30,000+ customers worldwide, which is exactly what you want when you are buying something meant to live on your wrist every day.
