Introducing: The Omega Aqua Terra 30mm, With Two New Master Chronometer Movements

June 18, 2025

For more than two decades (lest we forget the smoldering image of Pierce Brosnan from the original 2002 launch campaign), the Aqua Terra has served as Omega's go-anywhere, do-anything sports watch. And now, for the first time, the collection gets a dedicated 30mm case size. And, more importantly, two brand-new movements engineered specifically for it. The 12 new references span stainless steel, Sedna? Gold, and Moonshine? Gold, along with two-tone options, and offer a variety of dial colors, each with applied hour markers, as well as a clean date window at six o'clock. The watches sit on integrated bracelets with Omega's patented screw-and-pin system that features a butterfly clasp with side-pushers and a 2mm comfort-adjustment feature.? Omega has developed two brand-new Master Chronometer movements, Calibre 8750 and 8751, both of which are 20mm in diameter and specifically designed for the 30mm case. Small but mighty, they feature Omega's Co-Axial escapement, a silicon balance spring, and bi-directional winding with a power reserve of over 48 hours. They're also METAS-certified and offer anti-magnetic resistance to 15,000 gauss, meaning they meet the same rigorous standards as the brand's core offerings.?For clarity, the two movements have the same specs, but differ in finishing, with the 8750 applied for the steel and two-tone models and the 8751 found in the gold models (be it Sedna or Moonshine).?

What We Think Despite being a mid-size sport-watch wearer, I champion small mechanical watches that go beyond a gem-set bezel or mother-of-pearl dial. While we've seen progress in recent years, it's still rare to see a major brand apply the same movement innovation to a small watch as it does to a flagship release. And to be clear, I love gem-setting when it's done with intention, just not as an afterthought. In terms of its target, it's obviously hard not to see this as Omega's most direct answer yet to Rolex's smaller Oyster Perpetual. Similar sizing. Similar everyday versatility. But unlike the OP, the Aqua Terra 30mm delivers a transparent caseback and a movement that's arguably more advanced.?What Omega has done here feels meaningful. A 30mm case size with a brand-new movement built just for it. Both the steel and precious metal models are executed with the same level of precision, durability, and attention to detail as their larger Aqua Terra siblings. That speaks volumes about the brand's faith in this collection. The Basics Brand: Omega Model: Aqua Terra 30mmDiameter: 30mmCase Material: Stainless steel, Sedna? Gold, Moonshine?
