Well I made another attempt at doing my own battery replacements and it was again less than successful. It seems most of the Invicta's have a metal retaining plate with micro screws holding down the battery. I've got a set of small screwdrivers, but nothing that small. Are they available on the open market? Also, what do you do with a stubborn screw off case back? I have watch clamp but it kept slipping and I do not want to scratch the case. I need a watch repair 101 class!
 
You're good....I go to a super mall kiosk guy....for $8 it's done.
 
I bought a large watch holder on Amazon, a case opener tool on Amazon, and a set of screw drivers on eBay. I was able to remove the screws from 3 battery straps, but only able to replace 1 of the 3 screws. There was a plastic retainer for the insider that held the battery straps well enough, so I did not bother to replace two of the 3 battery strap screws [each of the 3 watches has one battery screw strap, not 3 screws on one strap].So right now, since I replaced 5 batteries, I broke even, but I have 3 more to replace.

[h=1]Watch Battery[/h]Posted June 13, 2014 by Esslinger Staff

[h=2]WATCH BATTERY REPLACEMENT GUIDE[/h][h=4]You know it’s time to change a watch battery… But what’s next?[/h]
There are several stages of watch battery replacement, and by following these simple steps you can be sure to successfully change your watch battery every time. Before you get started and purchase a bunch of tools, you should consider if you are just going to be occasionally changing watch batteries for yourself or if this will be part of your business. If you intend to change watch batteries as part of your business, it would be best to invest in a watch battery replacement kit, otherwise it would be more sensible to just by the tools you need for your specific watch.
For every case is there is always an exception to the rule. Always use extreme caution when working on any watch, but particularly when working on expensive watches. The key is to use common sense and keep an open mind: If you don’t think you can do it, take it to a professional.

[h=3]Step 1: TEST THE BATTERY[/h]Before you even open your watch case to change the battery, it’s good to test your watch to see if the battery is actually the problem. There are a variety of watch and battery testers that allow you to test a watch movement while it is still closed. To learnHow to Test Your Watch Battery, check out the articles here.

[h=3]Step 2: OPEN THE WATCH BACK[/h]When you know that the battery is actually the problem with the watch, you will need to open the watch case in order to reach the watch movement.
For help identifying what type of watch case you have and how to open your watch case, check out this article on How to Open a Watch Back.





[h=3]Step 3: CHANGE THE BATTERY[/h]When changing a watch battery, the actual act is fairly simple, but there are many things you need to be aware of beforehand to keep from damaging the watch movement. You must determine what kind of battery you are dealing with and what size replacement battery you will need. Learn How to Order a Watch Battery here.
Always try to note the battery number before you remove the old battery from the watch movement in case it jumps out of the case and gets lost. And when you are replacing the new battery, make sure it goes in the same way the old battery came out.
Some batteries are held in by thin metal straps or by spring loaded arms, and others need you to reset the movement before they start working again. To learn how to change the many different kinds of watch batteries, check out our article on How to Replace a Watch Battery here.


[h=3]Step 4: CLOSE THE WATCH BACK[/h]When you are finished changing your watch battery you will need to replace the back on the watch if you want to wear it again. For help learning How to Close a Watch Back, visit this article.







[h=3]REMEMBER:[/h]Only watches that have “Quartz” marked on them somewhere are battery powered. If your watch has a mechanical movement, there will be no battery to replace.
For every case is there is always an exception to the rule. Always use extreme caution when working on any watch, but particularly when working on expensive watches. The key is to use common sense and keep an open mind: If you don’t think you can do it, take it to a professional.



 
Thanks guys! I'll read the tutorials and have another go at it. I wish I had a mall kiosk nearby but everything in downtown Chicago is in the $15-25 range. And, I've got a lot of dead watches.
 
The most tricky battery strap hold down screws that I've come across are the tiny ones that are used in Ronda movements like the Z60.

ISA also uses them:

The main problem that I had with those screws is not that they're small, it's that the slot in the head is *extremely* narrow. I have five or six different precision screwdriver sets and none of the flat head screw driver tips would fit into that slot in the head. So, as always, I had to modify something to get it to work for me.


The thinnest screw driver that I have is a 1 mm one from this set that I bought for $1.50 at Daiso:


https://www.amazon.com/Daiso-Japan-Super-Precision-Screwdriver/dp/B01KS26KCG


Then I used this precision diamond file set that I also bought for $1.50 at Daiso and filed the edges of the tip of the 1 mm screw driver so that it was razor sharp:


https://www.amazon.com/9-8cm-Diamon...8219021&sr=8-11&keywords=Daiso+Japan+file+set


Note that I did not have to file the head of the screw driver much at all. All that I did was maybe 4 or 5 passes on each side of the head with the flat diamond file and that was all I needed to do to get the screw driver to fit properly in that tiny screw head. You do not want to file so much off so that the very tip of the screw driver is no longer flat and straight.


Note that most precision screw driver sets that I've seen on the market do not have a 1 mm size. The smallest that I've seen in most sets is 1.4 mm. That 0.4 mm width difference might not seem like much but it is a big difference in terms of the thickness of the tip and how much has to be filed off in order to get the screw driver to properly fit into the slot in the screw head.


I did this modification to my 1 mm screw driver a few years back and it works just fine every time I come across one of those tiny battery strap screws.
 
Instead of buying them piecemeal it makes sense to just buy a decent set like this one for $18.19 plus S&H which also comes with extra screwdriver tips for all sizes 9x screwdriver sizes 0.6mm, 0.8mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 2mm, 2.5mm and 3mm.
