GRAND SEIKO USHIO TIDE SPRING DRIVE SLGA015



Unveiled at Watches & Wonders 2022, the Grand Seiko Ushio Tide Early spring Drive SLGA015 redefines the actual practical dive watch having its strongly patterned black watch dial, exquisitely polished case in addition to ultra-precise Spring Drive activity. Mark McArthur-Christie points out exactly why Grand Seiko tends to be " a bit obsessed" and then stock shares his thoughts on this intriguing underwater timepiece.



Grand Seiko - somewhat obsessed

Describing Seiko as " a bit obsessed" is probably fair and a go with. Other watchmakers might get a dial from here, a set of arms there, a case from someplace else, but Seiko does it just about all in-house. It will also be of a high00 standard. Even a basic Seiko watch will have a look as well as quality that would be the jealousy of many other, more expensive companies. Then there's Grand Seiko. If Seiko is " a little obsessed, " GS is the kind of place just where every sugar crystal from the bowl on the staff canteen table is polished manually ,.



Grand Seiko Shinshu Watch Studio

This isn't just nitpicking in the interests of being nitpicky, though. The particular Grand Seiko Shinshu horological industry studio alone needs to keep on the watchmaking awards they may have won. The Men's Enjoy Award at the Grand Produits de la Horlogerie de Genève (GPHG) 2021 goes to the particular Hi-Beat 36000 80 Several hours cal. 9SA5. However , typically the brand’s talents are not tied to creating mechanical movements designed with the brand’s double-pulse escapement. Instead, they extend to be able to its unique Spring Drive mobility, like the one you’ll find inside Grand Seiko Evolution on the lookout for SLGA015.



Spring Drive - Ryoichi Akabane

To be fair, Seiko's attention to detail means Seiko doesn't rush anything. Watch manufactures cannot send anything to the world that is not nearly excellent. It took more than 20 years coming from Yoshikazu Akahane's initial understanding of the Spring Drive motion to 1999, when it grew to be the first model produced specifically in Japan. Since then, often the movement has gone through several manual-winding calibres and 21 automatic-winding calibres, until it is current two calibres. Typically the movement saw the light regarding day.



early spring driven pulley

Significantly has been written about the Spring Drive movement, so you possibly can say that it is a mechanical/quartz crossbreed movement that combines the most effective of both methods of keeping time. You get the " soul" of a mechanical watch, which includes its running gear coach (minus the balance wheel and also escapement), but with the reliability and reliability of a quartz watch. The escapement along with balance wheel are substituted by a " pulley" that will powers the watch's moments hand and is regulated simply by an electromagnetic brake. It is possible to identify the Spring Travel by the way the second hand won't tick or even stutter throughout the dial in tiny methods, it just slides. The best comparison is what the just a few seconds hand looked like on an outdated tuning fork Accutron movements.



9RA5 activity

In this case, the Grand Seiko Ushio Tide Spring Drive SLGA015 is driven by a 38-jewel Spring Commute 5 Days cal. 9RA5, self-winding movement. When totally charged, it can provide you with adequate power for 5 days and nights for continued use. With regards to accuracy, as you'd assume, the Spring Drive mobility is very precise, with an problem of just 0. a few seconds per day. It’s additionally a nice-looking move. The switch has perlage, bevelling, warmth blued screws, and the Awesome Seiko name in azure.



ISO 6425 standard

Just see that black dial. Divers work to be all boring previous utilities, right? Not in such cases. Grand Seiko tells us the texture on the dial should really reflect “…the dynamic and often violent tides caused by the actual Kuroshio Current…” This is the Kuroshio Current, which flows northern through Japan toward the particular North Pacific. It is one of many largest ocean currents on earth. Regardless of where Seiko got the theory from, it's an amazing one particular. The dial is just as understandable as a regular black call (still meets the ISO 6425 standard for dance watches), and it looks stunning too.



Lustrous hands

The cleaned hour and minute hands and fingers are clearly visible in opposition to it (as is the finished seconds hand with its lustrous lollipop base). That hour or so hand is almost a tall hand with three sectors of lume. The minute palm is the classic Seiko diver's flared arrow tip in addition to again has plenty of candela. All in all, it’s a great enjoy face in terms of legibility, quality, and fun. The utilized markup allows you to browse swiftly.



High energy titanium

Seiko will be making the cases for this certain series of watches out of whatever they call “high-strength titanium. ” After some digging, it would appear that this is not a case finishing method, but refers to the composition in the metal alloy itself; ti, iron, and niobium. Often the watchmaker also says the metal is more scratch-resistant than stainless, with a Vickers hardness level of 250-350 (stainless iron is typically around 150-250). Maybe luckily they decided to make use of titanium instead of 316L given that it's a chunky old circumstance, nearly 44mm in dimension and about 14mm thick. Huge weight savings - typically the metal they use is about thirty lighter than stainless steel.



Grand Seiko Ushio Tide Spring Drive SLGA015 - Case Finishing

As you'd expect from your Grand Seiko, the concluding of the case is done directly from the most notable drawer. There is usually a new brushed finish on the major case and a polished finish around the faces that join the edges and top of the case. The actual bezel has ceramic stuffing and is one of the clearest as well as smartest I've seen over a diver in a while, together with arrow markings underneath each and every number. Seiko did not layer the edges of the fine ceramic to allow the texture to show by means of next to the knurled advantage on the metal bezel aspect.



In fact , often the crown screws onto the smooth positive thread and is also protected by two heavy guards that flare out of your sides of the case. The bottom limit also screws down, and also Seiko are pleased to confess the entire structure will be water-proof to a depth of 200m - far more than just about anyone will ever need except if they make a living sitting in any saturation diving chamber. The particular mirror is sapphire ravenscroft with anti-reflective coating.
