Chancery Unisex Watch Repair Tool - Snap-on System, 12 Assorted Dies (24, 26, 28, 30, 31, 32, 33, 34, 36, 40, 42 mm), Crystal Glass, Professional Adults

What a great tool this is for pushing those tough watch backs back on...It's very well made and the nylon inserts (12 in all)...6 male and six female are reversable giving you 12 sizes in total and are very firm but not so as to damage any watch part such as the glass.or back plate..No instructions come with it...but to be honest...if you don't know how to use it,then you shouldn't be doing watch repairs in the first place..My first back I tried it on was my Botta Uno...this was impossible to put back on with fingers alone ( as are many other watches out there which are well made or give a good seal)...and after choosing the correct inner and outer nylon insert it snapped back into place with ease...no marks,no damage...I had several other watches also which needed to have the backs put back on and and this tool did every one with ease.. One tip I would recommend would be...Choosing the correct back plate die is just as important as the glass side...Choose the maximum size to go right to the edge of the back plate as this makes sure the back plate sits square on the watch case and pushes just the edge and not the inner part of the back plate which you might disfigure if to much pressure is exerted...Some people think that using a smaller size will do it...but as I just mentioned you might bend the back plate. For a ten pound note this is a bargain to do all those tricky back plates and make changing your batteries a much easier task..Recommended and super quick delivery too..Cheers

Very good product, well made and simple to use.I could not refit the back off my expensive Skagen watch, and did not want to risk damage.Also heard many Jeweller's will not risk them either.So bought this and a bit scary to use.However Only 4 stars due to lack of advice. DO USE U-TUBE OR SIMILAR VIDEOS TO GET BEST AND SAFEST WAY TO DO THE JOB. Very pleased

Saves a lot of money changing your watch batteries well worth it

Do not ever replace the snap on back of a watch without this magnificent tool.

Well whist we were in lockdown my wife's watch that i bought for her when we were married 10 years ago stopped , i thought it would be a doddle changing the battery and it was until it was time to put the back on, i used a bench clamp and crack , the crystal was smashed. So i looked on Youtube and saw the instructions for this clamp . I ordered a new crystal and replaced it and the battery , the watch now works perfectly. I would also recommend this kit from Amazon H&S 155 pcs Watch Repair Tool Kit , all the main tools are there for simple repairs https://www.amazon.co.uk/gp/product/B00BVG3JMS/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

works a treat but use a die which overlaps the back of the watch so it presses onto the clipping edge rather than on the middle of the back as it will flex and not clip in. the unit s pretty robust, would have got 5 stars except that the die threads were not cut into the plastic properly so didn't screw onto the press however it's a friction fit so you can push the press onto the die. not ideal and not as expected, but it still works.

Well made and does the job. Would be better if there were some directions describing exactly the best way to use it,ie: which sets of dies to put on the top plunger or the base screw size of the dies in comparison with the watch face and back, and that slow gradual pressure is better than heavy force. It is easy to crack the lens of the watch face if you are not careful. Size of each die should be marked for ease of identification. The produt lacks sofitication and some type of holder would be better than a bag of dies and a loose applicator. Not really good value but i guesse the best of a bad bunch. I think Amazon could find better quality and with a wallet case for this money or a much cheaper price for this standard of product.

I was surprised at how heavy it was but it did the job in about five seconds. Well worth the cost. I’ve struggled before with replacing the back on my watch- but this has solved that.
