Professional Watch Back Remover Tool, Metal Adjustable Rectangle Watch Back Case Cover Press Closer & Opener Opening Removal Screw Wrench Repair Kit Tool For Watchmaker

After about 3 years use, my first tool finally became worn enough that I thought I should replace it. The price for this tool is very reasonable, and should hold up to well to regular use.

The last time my Deep Blue diving watch needed a battery, I took it to a watch store, and they charged me $42 to replace the battery. Maybe they used an old battery, but it lasted 8 months. I put the watch in a drawer because didn't feel like spending another $42 to have the battery replaced, but I really missed wearing the watch. I wondered if there was a tool for the average guy to get the back off my watch and DIY the battery swap. I found this while hunting for such a tool, and figured for $7, it was worth a shot.The tool is made of metal and feels relatively sturdy. The fingers adjust to fit any watch. The back on my watch was on extremely tight (thanks watch store), but this tool successfully removed and reinstalled the back. Between the tool and a new battery, I'm in less than $14, and it took a grand total of 3 minutes to change the battery. This tool pays for itself the first time you use it. Even if only worked once, it still more than paid for itself...but again, it feels sturdy and will likely work several times.I am quite pleased with it.

I have many Invicta dive watches, and many of the "so called" great watch openers for those watches that have slots. I had two Invicta's that my great (and large 3-prong-type with handles) and expensive watch openers could not open. This product shipped quickly and when I tasked it on the first Invicta, with a little pressure, the watch back unscrewed perfectly. Amazing.I continued to open another Invicta's with this inexpensive, yet quite effective product. The one drawback I find is the mechanism is a little loose. The thumbscrew is quick to open and close the two prongs to your desired radius, but not snugly. There is some play, so I needed to just be sure to keep my thumb placed over the thumbscrew as I turned the radius. The product has some weight to it, which I like. and the prongs are well made-they are thinner than I expected, but sturdy when you torque on them. I'd give this a 5 rating if the mechanism was just a bit tighter. But for the price, and the fact that this product performs very well for me, I am surprised, yet pleased to recommend it.

Exactly what I needed to change my watches batteries, works great.

It works, but not easily. The teeth that go into the notches in the back of the watch are not very stable. The looseness of the teeth makes it difficult to get a secure fit. I am able to get the backs off of watches, but the process can be frustrating. I am looking to replace this one now that I am looking to use it more than once a year.

It was very easy to figure out how to use this. Now I can change my own battery - Great value!

Did not work for me. Returned after scratching the back of my watch.

This help me bring my watch back to life. Thank you.
