When prying something out (in this example, the battery), select and arrange your pry tool so that you're using your finger tips only. As opposed to using your shoulder or arm. The battery will still fly out due to the tension of the clips, but it'll only fly a few cm instead of a meter or two. I'd recommend inserting a small flat blade screwdriver (not your best one) and prying the battery out by slow fingertip twist action only. Once you adopt this overall concept, life gets easier. 🙂
The arm next to the coil can be pushed towards the coil and the battery will eject about 3 inches into the air. A 377 lasts about 3 years in that miyota movement. I agree with you that the innards of these large case quartz watches are underwhelming.
@@octaviussludberry9016 It doesn't matter, just that it's uninteresting and looks cheap compared to taking the case-back off a fine mechanical wristwatch or even a higher quality quartz watch.
Hello Greg. Are there any other watches other than Casio's Data Bank watches that utilize a 10-year battery? Do any Fossil watches utilize a 10-year battery?
FYI - touching the battery with your fingers can leave trace fingerprints across the insulation band, thus causing leakage current. Although the added leakage current is nearly infinitesimal, so is the watch current; so it's relatively significant. Of course it varies from person to person. Some people have slimy hands and leave obvious fingerprints everywhere they go (look at their phone screen), others have less goop poring out of their skin cells (their phone screens remain clean for weeks). Anyway, not recommended to touch watch batteries (across the insulation band), nor pick them up with metal tweezers (as it shorts the battery).
I have replaced the Casio Duro 200 mdv 301 twice with the Sr621w battery, and it lasts about 2.5 years. Last replaced in 2014 at Casio Center. Behind the metal case, I can't find the white plastic engine cover. Is it not there or maybe the center technician forgot it was not installed again. The watch is in good condition and is on
Interesting, this looks like the exact same movement that I found in my sister's small watch that's like 8-7 years old, just with a different dial face
It’s kind of like putting a flashlight in the off position when I change the batteries. It’s a habit which I have decided to carry over into working with my Casio Duro.
Its a Sailfish! hahah :) check out the difference... Marlins have different dorsal fins:) lol great video and fun to watch and learn. Keep up the good work!
I am guessing that pulling the crown out to the second click is just like turning a power switch to “off” and many watches are delivered from the factory with some kind of small, plastic piece designed to hold that position before the customer buys the watch. But this watch is generally delivered with the crown pushed in AND in the “screw down” position.
Still waiting for a mad lad to put on an automatic or a mechanical on one of these cases. Just to refer to the movement used. I know Miyota has several candidates for movements to put into these cases. A mechanical duro will be a cool addition to my collection.
It would be indeed. But Casio should put a Solar movement into one of these. The water resistance would be killed by opening the case back every 3 years.
Good video, but whenever a case back is opened it's a good idea to lubricate or maybe even replace the case back gasket. Lack of lubrication when the case back twists tight is when the gasket can rip. Lube on the case back threads also makes for a smoother fit, just sayin.
Hello Greg. Here's an interesting question that you might know the answer to - considering the fact that the energy capacity of watch batteries has significantly/dramatically improved since the early-to-mid-1970's, why is it that no watch manufacturer such as Citizen, Seiko or Casio has never to this day manufactured a solar-powered and/or radio-control LED watch? The problem encountered by the Hamilton Watch Company back in 1971/1972 when they introduced the world's first LED Digital watch the Pulsar2, which was the fact that the enormous power consumption required to illuminate the digital display repeatedly would drain the watch battery completely within 2-3 months, should no longer be problematic considering the fact that modern lithium-ion watch batteries supposedly last 2-3 years! In addition, watch manufacturers could design a solar-powered/radio-control LED watch to utilize a 10-year battery like Casio's Data Bank watches!
I bought a set of plastic ABS tweezers for changing Watch batteries. Would be a real shame to touch metal on metal whilst installing and causing damage.
Don't adjust the date wheel when the hour hand is in the top half of the dial between 9 and 3. Advance the time until it's in the bottom half between 3 and 9, THEN change the date wheel.
Bargain watches. Surprised it hasn't got a warning for a depleted battery, like jumping two seconds or something. I've been caught out by an analogue Casio in the past.
Suggestion: wrap a small piece of electrical tape around ONE arm of your tweezers or dip one leg into epoxy, so that you can safely grab batteries without shorting them out.
Would be great if Casio stopped playing around and made a smaller solar powered version of the Duro.
Not exactly the same face as the Duro but the Casio MTP-S110 is almost just what you asked for.
@@Digital111 I have that watch. It is a good size. That size in a diver would be awesome.
I see many ppl complain about solar watch…😂
Its battery is expensive…and also need to replace too!…
Around 10 year…lol😅
Yep, 40mm Duro Solar would be nice. With better lume preferably.
Liked the tip for setting the date time accurately 👍🏿
I bought 2 of these from my local Walmart on clearance for $11 each. green and black. My wife said why did you buy 2.......I said why not!
Why didn't you just say,"Shut up BEEP!"?😂
KIDDING I KNOW YOU AIN'T STUPID!😅
Thank you 😊 because I got 2 of that watch. The black and blue one. Look easy to change battery.
That’s cool you’ve got it in two colors. I’m very tempted to buy another one, too lol.
Thanks for video, was just concerned when I got the case back off and saw that plastic cover.
Small module in big case. Should be design for a larger battery that can last for 10years. Oh Casio.
Thank you for posting this helpful video. New subscriber. I enjoy and appreciate your channel.

Why does that matter? You don't see it. Others don't see.it. It's the outside that matters.

@@deathb4digital the only thing that matters is the reliability of the thing during time keeping. You're not going to see the movement much anyway.

using the 3 prong did not work to get the back of the case. Is that why you didn't use it?
Thanks Greg.👍👍
Great video thanks. Why did you unscrew the crown? Have not really seen other people take that precaution.
That's unnecessary, I never move the crown
@@nealriordan6802 me neither so I'm curious to hear his reasoning.

A good instructional video.
Does the watch continue to consume battery power when the second hand is not in motion?

Google 'watch silicone grease'
Mineral oil.

"Make that change!"
🎶😎🎶
If you pull out the stem when you aren't wearing it, the battery will last much longer.
Is there any way to upgrade the movement in the Duro so the battery life would be 10 years or close?
The Casio 2719 module is a 10 year analog caliber used in Edifice and heavy duty casios. Could it be used in the Duro?
for the price this watch is so good in accuracy and core strengh might not need anything
I bought a set of plastic ABS tweezers for changing Watch batteries. Would be a real shame to touch metal on metal whilst installing and causing damage.
After two months, I've determined that my watch is accurate to within +/- one to two seconds a month.
Thank u so much!
They really should have 2 sizes. This one is too big for some people and it's just 90% empty...
Gracias por tu vídeo 👍🇨🇴🕓🇪🇸
Wow such a small battery
個人で電池交換を行うと防水性能が下がる可能性はありますか？
crazy I have this exact watch and mine died on the 22 as well.
It looks like the left hold down has a small screw that can be loosened.....PS. I have the gold version arriving tomorrow, from Amazon......$40 USD.
need more kasyo
Don't adjust the date wheel when the hour hand is in the top half of the dial between 9 and 3. Advance the time until it's in the bottom half between 3 and 9, THEN change the date wheel.
I only use renata . Never use cheap battery's and always grease the seals back and crown
I was shocked to see that undersized movement.
For the price of this, don't expect a high end movement in there.
Three years
Miyota movement.
Greg you really have to to calm down and start wearing one watch at the time, mate 😂
Bargain watches. Surprised it hasn't got a warning for a depleted battery, like jumping two seconds or something. I've been caught out by an analogue Casio in the past.
這麼小的機芯卻配了這麼大的殼
Why is it so small
Miyota 2115 movement. 7 dollars from ebay. this is why..... ONLY solar and radio.
Suggestion: wrap a small piece of electrical tape around ONE arm of your tweezers or dip one leg into epoxy, so that you can safely grab batteries without shorting them out.
Why didn't you just go to a professional watch repair store? Casio certified?
well, you dont know what youre doing
youshould unscrew that piece to replace battery.
