In-Depth – The Grand Seiko Spring Drive UFA Ushio 300 Diver, GS’ Smallest and Most Accurate Dive Watch

While dive watches are fundamental to Seiko’s Prospex collection, the concept is slightly less natural for Grand Seiko. At first sight… Indeed, the higher-end brand of Seiko Corporation has been active in the field of purpose-built diving instruments since 2008, delivering impressive models, whether in terms of specs, looks or, unfortunately, size.

Watches & Wonders: Grand Seiko Finally Gives Us a Medium Sized Dive Watch, and it Includes a Spring Drive Powered U.F.A. Movement

If you were take a poll of Grand Seiko enthusiasts and collectors to ask them what they thought was missing from the brand’s catalog, I have a feeling a significant portion of respondents would tell you the same thing: a great dive watch.

First, there’s the movement, Caliber 9RB1, which has the same U.F.A (Ultra Fine Accuracy) designation as the 9RB2 introduced last year. The 20 second annual accuracy rate is, according to Grand Seiko, the most accurate wristwatch movement powe...

Gagà Laboratorio’s New Aqualab Pulls Off A Tricky Design Brief

When I heard Gagà Laboratorio was launching its first dive watch, the Aqualab, I was skeptical. The brand’s distinct identity made me question how it would translate into a sportier, tool-oriented direction. That’s a testament to the uniqueness of its design language, not a criticism of its existing watches. The Labormatic, for example, always struck […] Visit Gagà Laboratorio’s New Aqualab Pulls Off A Tricky Design Brief to read the full article.
