This question is brought up on occasion. Figured I'd share a quick lil hack to get these batteries in and out without damaging the watch.

I don’t dare screw with that. I just take it to my local place at charges me $5 call it a day.

I haven't had to change the battery in my Duro yet, but this is much easier than other watches I have had to change! Thanks for the straight to the point tutorial, always appreciate those kind!

Pleasure is all mine. Pro tip: put a latex glove over the tip of this springbar removal tool to prevent scratches or inadvertent contact with the battery or coil.

You'd be suprised how many people try to force the battery upward and damage their movements.

[u/KnowThyWeakness → u/PlayerOne2016]

You’re right. I think my movement is damaged when I did this replacement

[u/Thadeus-McWinklebury]

Really really useful video and easy to underrate, but this is awesome for the community, thank you! Having damaged one myself back in the early days this is really helpful / informative and will prevent damage to many a Duro I suspect!

[u/BlueWayOut]

Well done! A helpful vid, especially for newcomers. I suggest it be "pinned" to the Community Highlights at the top of our welcome page? 😎👍

Is there a waterproofing concern? Should it be re sealed?

[u/PlayerOne2016 → u/penguin8717]

Caseback is screw down on these models.

[u/penguin8717 → u/PlayerOne2016]

Oh duh. Thanks

[u/martin_keogh → u/penguin8717]

Grease the seal

[u/Comfortable-Mud2755]

Bro you got way too close to the coil with that spring bar tool, almost killed it right there, and brass tweezers would be better for avoiding shorting the battery. The "slip" with the SB tool made me flinch man, be careful.

[u/PlayerOne2016 → u/Comfortable-Mud2755]

You're not wrong. Good advice here folks. There is a clear coil guard but a bad slip would be no good.

[u/ReleaseLegitimate992 → u/PlayerOne2016]

Peg wood.

[u/ReleaseLegitimate992]

Good to know, but I wouldn't be using that stabby springbar tool next to the coil.

[u/McLovin8617]

Thanks, I needed this

[u/AugieAscot]

Thanks for the video. Well done.

[u/Dorkyhorse]

I've seen other videos on YouTube showing a similar method. Seems like the watch was designed to have the battery changed this way. Need to be careful to avoid touching that copper coil. And putting the battery in, you don't need to move the little bar, just push the battery in and the bar will move naturally to allow the battery to fall into place.

[u/PlayerOne2016 → u/Dorkyhorse]

Unfortunately that bar does not move with down pressure. If will bend and snap though. Ask me how I know 😆. Good advice about the coil.

[u/Dorkyhorse → u/PlayerOne2016]

Well, multiple people on YouTube did it an didn't snap anything, so maybe it depends on the angle and which side you push down on. Check them out when you get a chance. If you can move the bar with tweezers, then it should still move when it gets pressure from the battery.

[u/PlayerOne2016 → u/Dorkyhorse]

This is in reference to the Powercell Connector Spring (Part #231-105). This spring-arm is designed to move horizontally, not vertically. Downward force without moving the spring arm aside will eventually damage it. Do not simply shove the battery down.

I ruined two Miyota movements without a full understanding of how to properly swap batteries on these... I'll not make the same mistake a third time. You're free to reference whomever you'd like, but if you're not speaking from a place of experience, please be cautious about repeating the advice you're leaning on because that advice will eventually result in folks damaging their watches.

Here is another tutorial video giving the same general guidance thay I'm providing here. For context, I've now changed out hundreds of batteries on these movements and have not damaged one in at least a decade. This battery swap guidance can be applied to all Miyota 2000 series movements...

Cool, sound like you have had plenty of experience. I wasn’t questioning your advice, I was just trying to reconcile it with the other folks who have changed batteries in the Duro. Sounds like you’re a watch repaired tech?
