This is a very newbie question, but I always see descriptions/videos of how to remove casebacks, but I never see one that shows the type in my picture.  Is there some kind of special wrench tools for these?  I've tried the rubber ball, I always get the ball stuck on the lugs.  I thought maybe Jaxa, but I can't seem to get things to line up with the flathead type bits.  What's the best way to remove a caseback like I have pictured?

Thank you for any advice.

There are keyed wrenches which fit this type exatcly. You can still use a Jaxa if it isn't too tight. Otherwise, clean it and glue a handle to it to remove if it is very tight.

Are you sure that that isn't a snap off case back ? Some vintage watches had case backs shaped like yours but they were snap off. A picture from the side might help...

If you can't manage to open it I have another suggestion that I got from a watch forum once. Use a bit of super glue and stick something like a metal tool such as a screw driver or something onto the case back. Then use the tool to rotate the case back. Then simply clean away the glue from the case back and tool. Only did it once but worked great.

Is there a special name for these tools?  When I google watch wrenches, everything that comes back are just Jaxa wrenches.  I'll also try running the case knife under it to see if it pops off.

All I have is one of the typical adjustable three point back wrenches, but it works pretty well on those if they aren’t jammed too badly. Just adjust it so the points are across three of the flats. Works best if you have flat points in the tool not the round ones.

Here's my DIY tool I use when the sticky ball don't work.
Get a round plastic box with a flat cover, about the size of your caseback.
Cover it with duct tape, sticky side out, on one side.
Hold your watch firmly in one hand, crystal on your palm.
With the other hand place the "now sticky" side of your plastic box on your watch caseback and apply a firm pressure.
Turn both hands opposite ways, still applying a good pressure.
The caseback should unscrew.
The duct tape could let some sticky on you caseback ... clean with a q-tip and nail remover.

    • As a fellow newbie who's made a bunch of mistakes over the past year or 2 I'd like to offer my experience. I didn't start with a new practice movement, I started with 1970s Tissot that I loved. If I could do it over I would still use a vintage watch for my first movement. I wouldn't, however, chose one I cared about or that was expensive. It also had a calendar complication- dont do that. I learned a lot about part compatibility and movement families right away though! Emmy watch and Ranfft are great resources for this! I would start with the Benrus and go ahead and find a parts movement right away YOU WILL BREAK AND LOSE PARTS! Get good tweezers, it's much harder to handle tiny springs than YouTube would suggest. And be extra carful, pivots don't like to be forced into jewels - bridges are a real pain in the ass at the start. Don't be afraid to use your bare hands to hold parts/bridges and handle the movement. Finger cotts can come later. Be as carful as possible with hairsprings, this can ruin all the fun!  Buy a cheap demagnitizer. For me, I think its fine to buy cheap tools in the beginning and replace as you go. But some things I wish I'd have spent more money on right of the bat - TWEEZERS and Rodico (don't get the fake stuff). There's a great thread here on Chinese tools. I used a cheap digital microscope for a long time. I got quite good at working under it even with no depth perception. It's probably better to just use loupes but I think it helped me be more mindful and it was great for inspection. I now have a stereo microscope and if you get really into this hobby, it's a must. I cleaned everything by hand in the beginning. This is great for getting familiar with each part and learning to inspect for faults. Peg your jewels! I still hand clean a lot of parts before the ultrasonic. I still use JUST Naptha and IPA and I think thats adequate for my hobby purposes but maybe I'll have moved up in another year. I swish the shellaced parts in IPA for a few seconds to rinse (don't tell anyone). I used to dry each part on a sheet of paper with a puffer. Again, this is good for getting to know each part. I now dry everything in a food dehydrator. Im not going to give any advice on oil because thats suicide. But... until very recently I used just mobius 8000 and Molycote DX for everything. I dont know if I would do it differently If I were to go back but its definitely cheap and it will teach you how to apply oil.  Take a picture after every move even if it's just scratching yourself.  Wind mainsprings by hand until you decide you like the hobby, spend that winder money on tweezers and parts movements. This place is great, there are a bunch of incredible KNOWLEDGEABLE guys willing to help you. Unfortunately, this is as much as I can help, as I'm nowhere near their level.  Oh... and buy a big magnet. Still one of my favorite watches and it reminds me of all the broken pivots and pinged springs every time I put it on.   worth every penny.      
    • @RichardHarris123is that a pony chrono pusher?
    • The most important watch repair ever.  No not a long lost John Harrison or the like but my three year old granddaughter's.  £2.99 but "Grandpa, my watch is broken, can you fix it.  How could I say no?
    • I really don't want to come across as a nervous nelly, but am I right that any watch from 40s-60s with some lume paint is likely to be radium? Ww2-era ones splattered with paint are the obvious suspects, and I even started noticing ebay ads with radium burn on dials, but I see lots of designs where there's just a bit of paint on the hands and a few dots on the dial. Am I correct in thinking that i really don't want my kids to be licking and snorting the dotted ones either and I should just assume they are all guilty until proven innocent?
