How To Charge Seiko Solar Watch?

How To Charge Seiko Solar Watch
In order to recharge a solar watch, it is necessary to expose it to light. Since room light is weaker compared to sunlight, it takes a longer time to recharge the watch. Therefore, when recharging, please place the watch by a window and expose it to sunlight with the dial facing the sun.

How long does a Seiko solar watch take to recharge?

It takes about three hours of direct sunlight to fully charge most solar Seiko watches, and even in complete darkness, a full charge endures about 6 or twelve months depending on the watch.

How long should I charge solar watch?

If through a window, 84 hours. This means that with a window that gets 8 hours of sunlight a day a full charge could take 10 days. Solar Watch Charge Time.

Exposure Level Approximate Exposure Time
Outdoor Sunlight 5 minutes
Sunlight thru Window 24 minutes
Cloudy Day thru Window 48 minutes
Indoor Fluorescent 8 hours

How do you know when solar is fully charged?

Why 12 Volt Panels are 17 Volts? – The obvious question then comes up – “why aren’t panels just made to put out 12 volts”. The reason is that if you do that, the panels will provide power only when cool, under perfect conditions, and full sun. This is not something you can count on in most places.

  • The panels need to provide some extra voltage so that when the sun is low in the sky, or you have heavy haze, cloud cover, or high temperatures*, you still get some output from the panel.
  • A fully charged “12-volt” battery is around 12.7 volts at rest (around 13.6 to 14.4 under charge), so the panel has to put out at least that much under worst-case conditions.

*Contrary to intuition, solar panels work best at cooler temperatures. Roughly, a panel rated at 100 watts at room temperature will be an 83 watt panel at 110 degrees. Detailed information on MPPT charge controllers. The charge controller regulates this 16 to 20 volts output of the panel down to what the battery needs at the time.

What is the lifespan of a Seiko solar watch?

The Solar Questions – Since I purchased the Safari Series Seiko Tuna SRPF81K1, I have had several questions about how this compares to the older model I have, the SNE537P1, The most popular question seems to be, aside from the noticeable aesthetic differences, is the SRPF81K1 worth the extra money in automatic form? Essentially is the Solar movement any good as the SRPF81K1 is also available in a solar form SUT403P1 at quite a bit less in terms of price.

First off, my stock response to this question when I get asked on Instagram is yes, the solar movement from Seiko, In my experience, has been very solid, accurate and dependable. It requires minimal maintenance and has a battery life of approximately ten years. So what’s not to like or good about that? I guess this is where a simple question can be genuinely that simple or maybe a little more complex.

Everyone is different, and maybe this is the first foray into solar watches, or perhaps you have been collecting watches but usually lean more towards mechanical movements? Maybe you work in a low light environment, or this is a second or one of perhaps multiple watches and would be stored away for days or weeks between wears. All these things play into an individual’s view of what they need and if something is “good”. After all, good for me might be entirely inappropriate for your needs.

Let’s briefly look at how Seiko’s solar movement works and some of the pro’s and con’s of a solar-powered Seiko watch. Unlike a traditional mechanical movement which requires winding or movement to turn a rotor to then convert this into energy to power a watch, the solar movement through the use of a solar cell captures the light coming in through the watch face.

It then converts this into electricity which is stored in a rechargeable battery and powers the watch. This gives the wearer the ability to constantly top up the charge on their watch whenever it is exposed to light. Now it’s important to note that not all light is the same, and although it will still convert into electrical energy, the differences can be huge.

So shining a small torch at the watch will impart considerably less charge than wearing it outside during a sunny summer day. Regardless though, charging to some degree will take place. So then the burning question most people have is how long does a charged watch last? Well, Seiko say a single charge can last up to 6 months! So you don’t need to become obsessed with walking around holding your wrist aloft to the sun for fear of it stopping as soon as the sun goes down.

In actual-world usage, I have gone 2-3 months with my solar-powered Seiko tuna sitting in a watch box in the cupboard only to get it out and find all I need to adjust is the date. I make it a habit to get any of my solar-powered watches out at least one bright sunny day a year and leave them in direct sunlight for the day to charge. How To Charge Seiko Solar Watch This automatic version houses the 4R36 automatic movement But of course, a battery, even a rechargeable one, does have a finite life span, and Seiko says this is around ten years. So ten years of worry-free accurate timekeeping is what you can expect from these movements.

  • When it comes time to change these, it’s also something you may be able to do yourself, unlike servicing a mechanical movement.
  • There is a wealth of videos and instructions available on how to do this, and at the cost of around £20 for a new battery, it’s possibly more cost-effective to maintain it.
  • How about accuracy? Well, the V157 movement in the Seiko street series is accurate to 15 seconds a month.

Let that sink in. Yes, they are very accurate and over long periods of time, which is another big bonus of these movements. They make excellent second watches for a specific purpose, for instance, diving. This can be fully charged and sat in your kit bag, and is ready to go when you are without the need to wind it up and with no concerns over if it needs servicing for accuracy. How To Charge Seiko Solar Watch Note the dial texture which allows the light to pass through to charge the cell How about negatives? Well, when a solar watch stops, it stops. Obvious, I know, but you can’t simply wind it up on the go. It will take time to recharge, or you will need to replace the battery if you’re reaching that ten-year mark.

Maybe you’re just not in love with the thought of a watch that’s not purely mechanical? That’s fine too. I have both and enjoy both for different reasons. But maybe for you, Solar as a movement doesn’t quite have the wow factor of a fully mechanical movement. They are also not suited for anyone who works in complete and utter darkness year-round.

Think mole people or maybe reptilian overlords who live in the inner earth. All jokes aside, it’s hard to find many downsides to the Seiko solar-powered range. They offer worry-free accurate timekeeping that is grab-and-go friendly with low maintenance overheads compared to their mechanical brethren.

Why is my Seiko solar watch not working?

When the hands are stopped completely, there is a possibility of the rechargeable battery being out of charge. If this occurs, please recharge it by a window by exposing it to sunlight for 5-6 hours before using it again. In case the watch is used before a sufficient recharging, it may stop again.

How long do Seiko solar watch batteries last?

Seiko say its batteries in its solar watches should last 10 years. Additionally, Seiko recommends storing this kind of watch near a window with the dial facing the window so sunlight can recharge the battery.

How often do you charge a solar watch?

A Solar watch runs out of energy. What to do? – Try to recharge it often, and make sure to expose it to sunlight by a window for 5-6 hours once every month with the dial facing the sun. When not wearing the watch, make sure to put it in an environment where it will be exposed to light for recharging. When exposing the watch to sunlight for recharging, do not leave it on the dashboard of a car, etc. for a long time as the increase of watch temperature to an extremely high level can damage watch parts or cause malfunctions. Too much exposure to sunlight may damage or discolor leather and urethane bands.
