What i found inside.... looks like lighting strike occurred there.
Watch is sure dead as it can be.
My guess either someone tried to "charge" battery with 110V or something of this caliber.

That's why worst thing which can happen to quartz watch is DIY genius battery change.

Roots 2000.
Miyota based Canadian fashion brand watch. Why 2000? Because it has built in countdown to year 2000.
Such oddity looks strange today but it was a thing along Y2K bug and greatest celebration of millennia etc.

Good times, as agent Smith said when human civilization was at it's peak.

This was eating through a battery in under a year for the past few years. I got this before I acquired all of my tools and started changing batteries myself, so I had taken it to "watchmakers" a few times. After I started doing it myself I just replaced the battery with the same I found in there. I finally looked up the user guide for this module and found I've been using the wrong battery all this time, and it's specced for two years with the correct one. Coincidentally the same size battery I have in the mail for another watch. Also coincidentally opened another watch yesterday with the wrong battery installed by a watchmaker.

Just a goofy chain of events.

Same happens to me with a Ana-digi Casio. I feel i change its battery every 7 or 8 months, maybe i need to check the manual to see if its the correct one

Will post a photo tomorrow

So nice Pulsar bytheway

It happens with some "watchmakers" they squeeze or put smaller one as far as diameter goes. This one i assume takes 371? Or 395?

Seiko says SR726SW is spec which apparently equates to 397. It had an SR721SW inside it (which is apparently 621). I haven't looked up the specs of those batteries, but they appear to have identical diameters - the 726 is just a smidge thicker.

I have a DW-1000 with a 280 module, which takes a 2020 lithium battery. It had a 2016 inside.

Both 397 and 2020 are odd batteries...I had to go on Amazon to find them, and there were not many sellers/options for either. I have no doubt that you are right, the watchmakers took what they had on hand based on diameter size and tossed it in.

I am usually the kind of person to be like "let the pros do their job" but this kind of stuff has me taken aback. I think it's funny that I figured out two watches in as many days.

That one very old movement. I seen such oddities only on Swiss quartz. They like this "spacial" crap. 621 is very small cell and they don't last even in new watch, i assume in old one with sticky plastic gears it will drain cell faster due to higher torque on motor. I seen such things on old Nixon analog and some others. 397 is 0.5mm thicker and that actually quite a lot. It adds 10 mah to cell raising it from 23 of 621. In my observations older Pulsars/Lorus with full plastic "Seiko" are battery hogs due to sticking gears. Even if it looks fine on outside it could be lost case on inside. Had two NOS watches with battery life of 2.5 months. Shame. Once plastic starts to "bleed" it's done. Some Swiss full plastic movements are prone to this too. Mostly Ronda. At some point manufactures improved but it hardly helps if you got "lemon". Even if you wash away all sticky things it will return in few months. Done that.
