Seiko Prospex Radio Sync Solar World Time Chronograph Watch

Seiko Prospex Radio Sync Solar World Time Chronograph Watch Watch Releases

Seiko‘s now global Prospex series serves to highlight the brand’s best consumer tool watch designs. While certainly best known for dive watches, Prospex spans “Sea, Sky, and Land,” with focused and sport-ready products for divers, pilots, and travelers alike. This latest, the Seiko Prospex Radio Sync Solar World Time Chronograph looks to offer a pilot-focused mix of precision and reliability, which doesn’t seem like much of a stretch for Seiko. With a new radio-synchronized caliber and full world-time functionality, this new line of Seiko chronographs looks to bridge the gap between your aging SNA411 and their flagship Astron series.

The Seiko Prospex Radio Sync Solar World Time Chronograph is based around a 47.8mm steel case and will be available in three models, the SSG001 with a steel bracelet, the SSG005 with a calf leather strap and the SSG003, which is like the SSG001 but with a black hard coating on both its case and bracelet (seen above). Thickness is 14.5mm, and water resistance is 100m, with a screw down crown and anti-reflective Hardlex crystal. For those old school pilots that appreciate the flexibility, the SSG00X watches have a bidirectional rotary slide rule bezel along with world time markings on the rehaut.

Using the brand new caliber 8B92, the Seiko Prospex Radio Sync Solar World Time Chronograph’s functionality is largely established by its name. Radio synchronization has been improved for the new caliber so it can receive the calibration signals from further away and is capable of receiving signals from the transmitting stations in Japan, China, Germany, and the U.S. Under ideal conditions, the time is synchronized up to three times per day or at the push of a button. Being a quartz movement, accuracy without synchronization is +/- 15 seconds per month. Further adding to the convenience of this new Seiko movement, the 8B92 is solar-powered and can recharge its internal battery while you enjoy a sunny day above the clouds.

For the frequent pilot or traveler, that radio sync accuracy is bolstered by the inclusion of a 60-minute 1/5th resolution chronograph with split time, a perpetual calendar, a 24-hour display, and world time capability showing the time in any of 25 timezones. It’s hard to top the multi-role capability of a GMT chronograph and the Seiko Prospex Radio Sync Solar World Time Chronograph offers a fuss-free, practical, and very accurate platform to get the most out of its functional feature set.

While the case sizing is quite large, the dial is legible and nicely detailed, and, being a Seiko, we can likely assume the hands and markers will be well-lumed. The SSG00X models are almost Seiko’s answer to a Casio MR-G, with solar power, radio sync, sporty designs, and a handful of useful features. Prices will range between 640 EUR and 730 EUR (roughly $720-$820 USD), with availability starting in August of this year. As long-time fans and users of Seiko’s Prospex models, it’s exciting to see them develop new platforms and expand on their core strengths. seiko-prospex.com

    Is it safe to say that for the person who has no allegiance to mechanicals, who wants to know the time (the exact time) everywhere, who travels, and does not want to pay for superfluous decoration, this is the ultimate watch?

    • word-merchant

      Or that person could save a bit of money and get one of these: http://www.gshock.com/watches/G-Steel/GSTS110-1A
      which as well as being cheaper looks just like a Hublot Limited Edition Big Bang Yada Yada from a distance.

      • iamcalledryan

        lol – one hell of a distance (and from behind a wall)

      • ZL

        I, for one, will definitely be getting a G-Steel, and most likely that exact one!

      • JimBob

        The goggles do nothing!

        • Average Joe

          Up and at them!

    • I agree with that assessment — it really feels masculine and purposeful. A monochromatic companion for life as it were.

    • Simon_Hell

      Man, inspite of the obviously condescending overtone, you nailed it. Its me you’re talking about, like you’ve known me all my life. This is a wet dream come true, the design is right on the money. And the diamater, of man! I have skinny wrists but at 6’6″ i look funny with anything other than a 46mm+ watch. There are quite a cew good looking watches in the seiko and citizen lineups, but they kiil it with their 42mm diameters. This is just perfect.

      • iamcalledryan

        Actually this was one of the few times I wasn’t condescending – I guess it sticks…

        I think Seiko are outstanding.

    • egznyc

      The only thing you left out of this assessment is the large size of the piece. If it were 5mm smaller, I’d seriously consider it as a great travel watch. And I DO owe my allegiances to mechanicals ;/)

      • iamcalledryan

        Then you sir, are a maverick!

      • Morsa85

        I know this is a year old, but yes this is, for me, the 21st century tool watch that you could also wear with a suit. I say could because 47mm is out if my league. If it were 44 i would buy it in a heartbeat. And even though i love mechanical chronos, yesterday tool watches are todays unatainable jewlery. Shame.

  • outremer

    What a relief would be if a watch was named A1.

  • 1droidfan

    Needs more tick marks.

  • wallydog2

    I had a friend in High School (in a previous century) who was a slide rule/pocket protector type. He’d have loved this watch

  • Sevenmack

    This may be the radio controlled I may buy this year. A little too busy. But also rock solid.

  • Ulysses31

    Quite stylish for a Seiko in this category. The bezel and dial are a nice matte finish which I prefer in a “tool” watch. It’s busy, and there are those superfluous screws, but it’s a good effort. One thing that continues to bother me is that even at a relatively high price (for a quartz watch) we don’t get solid end-links. Other manufacturers offer this but Seiko still provides those ugly pressed-steel pieces which really make me cringe. A sapphire crystal wouldn’t hurt either.

  • JimBob

    The Seiko case and bracelet designs always end up killing the deal for me.
    The fuel consumption slide rule is the most pointless waste of bezel real estate possible. This watch also needs less space devoted to rehaut. I guess they wanted it to look like an old military compass or something.

  • JosephJabez

    Can it show dual time?

    • JosephJabez

      The reason I ask is because the review mentioned about showing world times capability but I do not see any hand or smaller clock showing that.

  • Average Joe

    Love this watch! Any idea if it’s like the IWC Timezoner in that it compensates for Daylight Savings Time, and knows which regions observe and which don’t? Of is that too much to ask from a sub-$12,000 watch?

  • PleaseSpellRoman4AsIV

    Petty that the date window break the otherwise symmetrical layout. But still good value for money.

  • BadgerHeel

    I agree that this would make a decent travel watch, but gargantuan case sizes like this keep average-sized guys like me (5’9″) out of the game.

  • Mark Baran

    I don’t understand the fuel consumption bezel at all. Maybe they were trying to do something different, so it does not appear to be the “Son of Astron.” If I wanted that functionality in that size range, my choice would be MR-G.

    • Average Joe

      It’s a standard E-6B flight computer. For fuel consumption, just rotate the “rate” indicator –the 60 — and put it opposite the rate per hour. So for example, 15 gallons. Then you find the time on the middle scale in minutes (or the time in hours on the inner scale), then the total number of gallons consumed during that time on the outer scale will be opposite. If your time was 2 hours, you would see the answer 30. But it’s a logarithmic device, so 30 could represent .3, 3, 30, 300, 3000, etc. You have to keep the decimal place straight in your head. It’s a brilliant device. But you have to really see it in action to really understand how it works. A device this tiny would be difficult to use because the tick marks are so small.

    It needs a “Hello Seiko” app so you can ask it to toggle thru all it’s functions…. especially at that size you could anchor it to your aircraft cockpit or strap it on your thigh like B17 pilots did…. but Seiko knows how to price the market to make the sale with excellent quality.

  • mtnsicl

    It’s a beautiful watch and it’s just barely within the amount I would pay for a Seiko.

  • Larry Holmack

    Oh yeah…I am loving this one!! 47.8 mm….perfect size for me….and not so pricey that I can’t afford it! Hopefully the local Sam’s Club or Costco will have them….as you can get some smokin’ deals on watches there….and I have purchased some nice Seiko’s at Sam’s before.

    Thanks for the nice article James!!!!
