Swiss Army Cavalry (Old) Battery Replacement 

It's very difficult, I haven't been able to pry mine off with my tool.

@@patriciamiller4330 I was able to get mine off somewhat easily once I found the best blade in my pocket knife. It was the blade that had the most substantial curve to the blade side. I wedged it between the wrist strap and cover, pretty much like he's doing in the vid, and it came off without much effort. The cover also snapped back in place easily also without special press he has, just lay it on the table and apply even pressure with both thumbs. Good luck with yours. Oh, and btw, it's a good idea to clean all the surfaces on the cover and watch that make the seal with the o-ring, they were quite dirty, used a q-tip and alcohol.

@@imnotabotrlyimnot Thank you, I'll try that.

I've had a similar model for years and was only able to get the back off once by almost destroying a knife edge. I have to take it off again and it's on there just as tight as before. I think a flat blade screwdriver is needed at this point.

The back on mine is also very tough. Tried for a while with 3-4 different tools and nothing. Last ditch - I ordered a bezel removal tool (like a vice). If I do ever get it off, I'll file down a small spot so there's room to stick a tool under it next time.

michael 1 : Yeah, the Cavalry I picked up in ‘04 was NOS that some place must have had a fire sale on so it was bought at a discount, but they’re probably all sold off by now and ppl are either using them, or they’re sitting in drawers with dead batteries. :( There’s actually a used one on fleabay right now, so you never know you might get lucky?

I just found my dad's old cavalry, he got it from a Marlboro catalog about 20 years ago fixing it up now can't wait to wear it!

My Swiss Army Calvary watch only lasted about 8 years before it broke. I thought it would last longer. Anyway it's not 100% a Swiss made watch.

Same here. I tried sharpening the edge of my case tool but it just chipped. I ordered a bezel removal tool which looks like it also works for snap backs. It looks like a vice with 2 sharp wedges attached at each jaw. 🤞

Exactly my problem, good grief, it's a $25 watch. I had to take it to a jewelry store. Wait until you try to get the case back on the watch. Impossible. Never buy this brand again.

@@rickrounds2173 this watch originally retailed for $200, and its designed to be opened with special tools.

The one I own has a Ronda 315 movement (no longer made).

What i did was buy a Nato strap 18mm is fine

Richard Marshall Es braucht Uhrenöl, ich habe diese Uhr und ich hatte dieses Problem schon einmal

Yes, you are correct. He should be using plastic tweezers.

I'll sell you mine CHEAP but unless you have a watch press, good luck with replacing the case back.

@@rickrounds2173 Thanks

I have the 3888 model. Does this 392 work?

@@gerardovargas7389 YES IT DOES
