Boasting 55 hours of power reserve when fully wound, it is also finely regulated, with a claimed accuracy ranging from -3 to +5 seconds/day (well within chronometric standards). It is 40mm wide and 13mm thick (water resistant to 100 meters). The design of the case is somewhat classic Rolex inspired if you know what you are looking at. It is the archetype nice steel watch on metal bracelet. Under the screwed back is the calibre 9S85, an automatic movement characterised by its high frequency of 5Hz or 36,000 vibrations per hour. The design of this Grand Seiko Hi-Beat Automatic Ref SBGH005 watch overall is classy and tasteful. The display is complemented by a framed date window at 3 o’clock. All the elements are largely filled with LumiBrite, and contrast well over the dark matte blue or matte black background. The same goes for the hands, each having its own distinctive design, to ensure that the time can be read easily and without error. It features oversized applied indexes, which are identical to the now discontinued SBGA231. The dial is simple and typical of dive watches, with legibility and contrast in mind. Nevertheless, high-beat movements are exceptionally cool and come with two notable advantages. As you can see, there’s a slight difference in texture and colour between the two cases. SBGJ219, one of the brand’s Hi-Beat GMTs. It comes with a black dial and has a gold-coloured GS logo. The 61GS developed from a base Seikomatic 5, powered by a 6145 automatic Hi-Beat (36,000 bph) caliber with 25 jewels. The other version, the SBGH291, is housed in a High-Intensity Titanium (with hard coating too) case and a matching bracelet, allowing for lightness, resistance and comfort on the wrist. The first model, the SBGH289, comes with a stainless steel case and bracelet, both with hard coating, as well as a deep blue dial. In fact, if you look back at the brand’s recent history, these new 200m Diver SBGH289 and SBGH291 could well be the automatic counterparts to the well-known Spring Drive SBGA231, since it brings back most design cues, yet with a different movement.Īs said, there are two versions of the Grand Seiko Hi-Beat 200m Diver presented today, and the difference is not only about the colour of the dial. Slightly less rugged, slightly less massive, but still performing well underwater, or simply with a casual attire during the weekend. Today’s watches are less instrumental, and more what we’d call classic recreational dive watches. It has even provided some truly impressive models, such as the SBGH255 and SBGH257, or more recently the SLGA001 that also came with a brand new Spring Drive movement. Grand Seiko is certainly no stranger to the dive watch category and has been playing around the concept for many years now.

Meet the new Grand Seiko Hi-Beat 200m Diver SBGH289 and SBGH291. Today the brand is releasing two new classic watches in its family of sports models, with Hi-Beat automatic movements and typical GS specifications.

While Grand Seiko has been focusing recently on the development of its Spring Drive movements and on a slightly refreshed design language oriented on nature – look at the mighty White Birch to get a good example of that strategy – the brand is also a solid provider of sports watches, including highly robust diver’s watches.
