The brand Circula was born in Pforzheim, the watchmaking heart of the Black Forest, in Germany. It was founded in 1955, so you can see that the watch I’m reviewing today was produced by an experienced company.
After the release of the Classic and the Heritage, Circula is now coming with a retro Divewatch, the AquaSport.

The AquaSport was inspired by Circula diving watches from the 70s. The pillow-shaped case alternates brushed and polished finishes in a contained width of 39mm and a thickness of 12.8mm. Although it might be too small for those with lumberjack wrists, these are the dimensions one can expect from a watch meant be retro/vintage.
The thin screw down crown is located at 3 o’clock and is engraved with the brand’s logo. I must admit it was a bit difficult to screw it back in without actioning the bezel, but the blame goes to my (too) big fingers. The coin-edge bezel features a scratch-resistant sapphire inlay which might be a bit harder to read compared to a ceramic one but it sticks totally to the vintage identity. I really like it! One can add that it’s perfectly aligned and doesn’t suffer from too much back-play.
As mentioned in the specs, the sapphire glass is slightly curved. It’s also efficiently AR coated, allowing for a good legibility in most situations.
The AquaSport’s dial is absolutely gorgeous! The main part of the background is dark blue and embossed with waves, while the outer part is made of a white layer above the blue one and receiving the orange and cream indices. This color scheme is specific to the version I’ve chosen, there are other variants available at Circula’s website.
Just like the color scheme, the AquaSport is available with multiple movement options. I went with the most affordable one, the STP 1-11. I won’t start a debate around the available movements, IMHO they’re all qualitative and satisfying. Should you go with the COSC Sellita SW200, you’ll obviously get the best option. Hats off to Circula for offering the choice between those 2 and the ETA 2824-2 at a more than reasonable price point.
The Stainless steel Beads of Rice bracelet features a quick release system as well as 7 fine adjustment positions. I’ve immediately found it very comfortable, but be aware that you can also get a matching tropic rubber strap.
The Circula Aquasport is quite different from the watches I’m used to wear. Not only is it smaller but I also must confess that I’m generally not a retro watch guy. That being said, it’s with a real pleasure that I wear the AquaSport! Its quality goes beyond expectations and it carries a genuine identity, which is more than welcome. One can definitely feel that Cornelius Huber, the founder’s grandson, has a strong experience in the watchmaking area and he really knows what he’s doing. I warmly recommend you to pay them a visit!
