Revisiting Our Hands-On Review With The Grand Seiko Spring Drive U.F.A

Grand Seiko’s Spring Drive U.F.A has an astonishing ±20 seconds per year accuracy. Wrapped in a new slimmer Evolution 9 case and finished with a dial inspired by winter in Shinshu, it’s a masterclass in subtle innovation and timeless elegance. What We Love The Calibre 9RB2 delivers an incredible +/- 20 seconds per year, redefining what is possible from a mainspring-powered mechanical movement The new 37mm case size makes the timepiece highly wearable for a wide range of wrist sizes. The beautifully textured dial captures Grand Seiko’s unique blend of craftsmanship and storytelling. What We Don’t While very comfortable, the standard three-link bracelet feels a little too plain for a release of this calibre. For a groundbreaking caliber, the caseback view feels a little subdued. For such a significant release, the design feels a little too in line with previous Evolution 9 models. Overall Rating: 9.25 / 10 Value for Money: 9.5/10 Wearability: 9.5/10 Design: 9/10 Build Quality: 9/10 This article was originally published as Hands On With The New Grand Seiko Spring Drive U.F.A.

Omega’s Small-But-Mighty Movement in the Aqua Terra 30 mm

Omega’s latest Aqua Terra is a competent women’s watch with a brand-new calibre that is both compact and proficient. Equipped with the new cal. 8750/8751, the Aqua Terra 150M 30 mm launches with a healthy mix of metal variations and dials across 12 models that will surely expand in time. Initial Thoughts Despite scarce coverage in watch media, watches made for, and marketed to women are very important to the industry. And, women have rewarded brands that put in the effort with enormous success. The Lady-Datejust, for instance, is often rumored to be Rolex’s highest volume model. While Omega offered an Aqua Terra 30 mm in the past, the Constellation has arguably the brand’s champion in the segment for the last few years. The new Aqua Terra 30 mm might look similar to its predecessor, but it stands out for the new cal. 8750/8751 that is a Master Chronometer-certified movement. Building a movement that can consistently meet Master Chronometer standards, while being small and thin, is an achievement on its own. All else being equal, larger movements perform better than smaller ones; the difference is significant enough that the ISO 3159 chronometer standard that form the COSC testing standards has less stringent requirements for movements 20 mm and under. Options Omega’s watches are often, and fairly, criticized for being unnecessarily thick, but that isn’t the case here, thanks in part to the new caliber. All steel and two-tone models are 10.6 mm tall (10.7 mm for...
