I put off buying one of these arbor style caseback removers for many years because of the high investment cost of both the Bergeon or Horotech versions of this tool. I use many of the aforementioned brands of presses and bezel removers and hand presses and such but had to pump the brakes at >$1k just for a caseback remover. I just stuck to the old Jaxon style wrench and proceeded with a lot of caution.I accidentally stumbled across this affordable priced version on Amazon and despite the mediocre reviews, I decided to give it a try and if it didn’t live up to $145 worth of my expectations, I could simply return it thanks to Amazon’s generous return policy.The tool arrived in quick fashion, very well packaged and was more than I’d ever expected…well worth the cost paid. Fit and finish were very good, all the bits and pieces were accounted for and they snapped in very well. This thing makes waterproof watch caseback removal so much more peaceful. It just works! It works well and I only performed two very minor enhancements to make it suit my tastes.First, the arbor return spring that holds the arbor up-off of the watch was ever so slightly weak feeling with the weight of tool head when installed so I removed the shaft, stretched out the spring and while I was at it, I wiped off the cheap feeling factory grease and applied some of my favorite red lithium machinery grease. This made it spring back with good motion and the heavy weight grease made it move much smoother.Secondly, the tool tips that fit into the caseback slots were ever so slightly sharp from the machining process. As they were, they could scratch a highly polished back so I chucked each one up in a hand vise and polished/deburred the tips on a bench mounted, scotchbrite buffing wheel.The tool is now 100% functional to my liking and a great buy at $145. A very worthy alternative to a Bergeon or Horotech style tool. I’m glad I found this and with maybe 30 minutes spent on my enrichments, it’s well worth

Like other customers of this watch opener, I have advanced from buying watches and just switching out bands, to actually modifying the watch to my liking. This includes dials, hands, bezels, chapter rings, bezel rings, and crystals. Most of these modifications require you to get into the watch. After scratching up the back of some prized watches, I had it, and decided to go ahead and invest in a professional watch opener, instead of fumbling with those hand-held openers. They do the job, but I was no longer willing to take the risk of scratching up a case back (not very professional) - especially if a friend trusts me to work on their watch. Mine did not come with instructions, so YouTube it is. The item page in Amazon has the best info for now. I use the 2 lug holders (dies) instead of the 4 case holders (see pic), as these seem to center the watch case under the vice better (since the accessory watch holder for odd-shaped watches did not center it properly). Sufficient lighting is needed so you can see the vice chucks fit into the case back grooves snugly. It does have some heft to it, comes with plenty of accessories, and feels like a quality item. The tiny hex wrench supplied does not fit the set screws for the chucks, but they did not fall out.

After using on several watches it is still working like new!

I gave it 4 stars because it's fine for a hobbyist with infrequent use. Mine required modification to install the oyster fitting holder. I had to carefully file it for about 20 minutes with a jeweler's file to make it fit into the main shaft. It's not great quality but it definitely gets the job done. The seller did a horrible job packing the tool. They put absolutely no packing inside the shipping box - zero!! The tool knocked around inside the box and opened a couple holes. Fortunately, none of the parts got lost. I got lucky.

Exelente herramienta

After scratching 3 watches with 3 prong tool that is almost impossible to keep aligned to unscrew the case, I bit the bullet and bought this tool.I have successfully opened 7 of my screw back watches. 3 of them were opened without any additional scratches.

This has been one of the best birthday gifts I have gotten. It has been great to work on my watch collection.

Todo muy bien
