Omega has clearly decided that turquoise isn’t a fanciful fling, it’s a committed relationship. This summer the color returns to the Seamaster Aqua Terra collection in two sizes — 38mm and 41mm — but the mood has shifted. Last year’s bracelet pieces were ready bordering on dressy, but these new references turn up to the party in sneakers. The change is simple and sensible: a matte black ceramic bezel and a fitted black rubber strap stitched in turquoise to match the dial. Same bright face, but less shine and more purpose.

The rest is familiar Aqua Terra and that’s no bad thing: 150 meters of water‑resistance, a screw‑down crown, a domed sapphire crystal with anti‑reflective treatment and the wave‑edged caseback that reminds you this line’s history is maritime, not boardroom. The dial is still the star: turquoise lacquer that darkens towards the edge referencing water, with a high‑contrast minute track. Hands and hour markers are black PVD and the lume glows blue.

The strap is definitely worth a note. Omega didn’t bodge an end‑link onto a straight case; the modern Aqua Terra was designed to accept fitted rubber, so the transition from case to strap looks sleek and feels secure. In hot weather it will wear cooler than steel and it visually ‘tucks’ into the case, which helps the watch look more compact.

Ceramic on a fixed bezel is another pragmatic call. It won’t pick up the fine scratches that drive some owners to distraction and the matte finish calms the dial down just enough. By framing the color with black rather than polished steel, Omega tightens the design so the turquoise looks deliberate, not decorative. The usual caveat applies, however; while ceramics laugh in the face of abrasive substances, they don’t always come off the winner if they meet a granite worktop at speed — although in everyday use the upside is definitely what you’ll notice.

The 41mm model houses the Co-Axial Master Chronometer Calibre 8900, while the 38mm version features Calibre 8800

Inside the 38mm model is the Caliber 8800 with a 55‑hour power reserve, while the 41mm is equipped with Caliber 8900 with 60 hours of autonomy. Both are Master Chronometer certified, so the cased watch is tested for rate, water‑resistance, power reserve and resistance to 15,000 gauss of magnetism.

As for the color, turquoise is not exactly rare air in watchmaking and especially not around water. If you need a physics footnote, shallow bays read turquoise because red light drops out and blue‑green gets through, which is also why this hue feels “correct” on a watch with sea legs.

Doxa made bright sea tones a signature long before social feeds discovered them; TAG Heuer and Breitling both run credible turquoise options in their aquatic lines. Omega’s own “Summer Blue” program showed a brand comfortable working with variations of color and these new Aqua Terras sit at the sunny, shallow end of that story.

How will they wear? On paper, the 38mm concentrates the color and has a tighter read; the 41mm gives the gradient more room. The ceramic bezel should hide the kind of daily scuffs that polished steel loves, and the rubber will deal better with sunscreen, sweat and the occasional dip.

The Aqua Terra remains the Seamaster you actually wear every day: rated for real water, resistant to the magnets that lurk in 21st‑century life, and now framed so the color feels like part of the plan. If you want rotating‑bezel drama, buy the Diver 300M. If you want a single watch that does city-to-seaside chic, this could be the one.
