Hands-On: The Grand Seiko Spring Drive Diver’s 200m
Right in this whole problem is the Seiko Grand Seiko Spring Driver Diver’s 200m – which isn’t just a jump watch, yet a Grand Seiko plunge watch – what this implies, we’ll find in a moment. This is a huge (44.2mm x 14mm) and rather greatly fabricated treated steel plunge watch, which satisfies all the requirements of ISO 6425 – that is the worldwide norm for jumper’s watches, which determines, in addition to other things, a unidirectional turning bezel, water protection from at least 100 meters, a capacity to oppose magnetic fields up to 4,800 A/m, and different guidelines for fundamental stuff like stun opposition, protection from consumption, etc (you can peruse the whole thing here. )
It’s an amazingly tasteful piece of work, yet in a technical/utilitarian way; it doesn’t quite feel like an unadulterated, unadorned piece of equipment (in contrast to its far off cousins, Seiko’s entrance level plunge watches like the exemplary SKX007) nor does it seem like a totally practice in quietly urbane extravagance (in the same way as other of the other Grand Seikos). Inside is the Spring Drive type 9R65, which utilizes a quartz tuning fork resonator, requires no battery, bolsters a power save pointer, and is appraised by Seiko to run within +/ – one second out of each day. (Spring Drive, in case you’re inexperienced with it, is a technology unique to Seiko – there’s a traditional fountainhead and stuff train, yet it closes in a “coast wheel” that is turned by the stuff train to create current. The current powers two electromagnets that brake the float wheel, to control the speed at which the pinion wheels turn – filling a similar need as an ordinary escapement. It is anything but a standard mechanical watch, however it is anything but a standard quartz watch either – the most noticeable distinction is that the seconds hand doesn’t tick, yet rather floats easily and absolutely quietly around the dial.)
The first question is, does this work as what a great many people will wear it as: a day by day wear/wear everywhere sports watch that is sporadically expected to go in the sea, pool, or shower without making a quarrel about it? Our answer to that will be that totally it does – the quality of the casework, dial and hands, and the significant degree of finish on the arm band all make it a consoling watch to wear – the more you take a gander at it, the more there is to like, which is surely not always obvious. It’s worth referencing that this is quite possibly the most shockingly fulfilling timing bezels you’re at any point prone to experience; it’s smooth as margarine and simultaneously, amazingly exact in feel, dominating most other plunge watch bezels in believe similarly pusher feel in a top-end chronograph beats more passage level stuff.
There’s without a doubt a noticeable family relationship with the SK007 yet while that watch feels as stripped-down and intentional as a GI’s oil firearm, the Grand Seiko Spring Drive Diver’s 200m is brilliantly well-crafted.
The second question is, is this a viable plunge watch? I will answer that question to the most amazing aspect my capacity, as, as a matter of fact, a non-jumper: it sure looks that way to me. There isn’t anything here to recommend that it will in any capacity disillusion whenever utilized for its expected reason. There is all that you would expect – a very well ensured crown, marvelous perceivability, a simple to work wetsuit expansion (for reasons unknown, we really have a wetsuit in the workplace and part of the gang took one for the group, stripped to the waist, wriggled into the coat and took a stab at the watch; the augmentation worked as planned).
But there’s somewhat more going on here. Spring Drive, all things considered, may simply be the most amazing aspect all potential worlds when it comes to plunge watch technology. Its exactness is around a significant degree better than a mechanical watch (and many Spring Drive owners episodically report far and away superior execution) and dissimilar to quartz, it doesn’t have an assembled – in disappointment mode in light of the fact that there is no battery (a point that is frequently neglected when talking about spring drive). The power save pointer on the dial gives additional affirmation that there’s sufficient juice in the tank that you won’t out of nowhere locate a dead watch on your wrist.
It’s a somewhat desolate situation to have, given the Quixotic idea of making jump watches in the time of electronic plunge computers, however it’s a good one, and for owners, it is anything but an awful inclination to know that in case you’re wearing one of these, you’re wearing a truly well-made, intense yet extravagant games watch – you’re wearing what likely could be the most technically progressed broadly useful plunge watch that is at any point come down the pike.
