Thanks so much for your response. When you say that it did not work for large watches can you be more specific on the size. I need it for removing the back on a waterproof watch that is about 48 to 50mm in diameter. Will it work? Thanks again

I haven't used it for any that large but I expect it will work. Worked fine on several smaller watches of varying diameters.

I would say no. The sizes probably go down to a Phillips 0000 or so, not near small enough for watch repair.

I have a 50mm watch with a rubber strap, and it fits on the top drawer. The bottom drawer is quite less spacious, even my regular diver watches are a tight fit there.

They are smaller enough for case screws (I mostly use the 0 pt Philips but the flat head did pop the case off once unscrewed and popping the battery out was easier using a tool) since I just opened the back of my Timex 100M (10 bar) Expedition watch which uses screws instead of screwing on like fancier dive watched do. So for changing batteries fixing glasses, even open up your cell phone it will work but not for any tiny inside parts. You might also want to look at getting a watch repair kit. They often go for less then $20 but if you are just removing screws it will do that much. I got my set at home improvement chain store when it was a "Special Buy" item but it's the exact same item.

There are 3 types of watch backs commonly used. The first type has a rotating bezel which is alternately grooved up and down at the edges. This will work here. The second type is like a cap with a small slit at the edge. You can insert a mini screwdriver into the silt and gently hammer it in till the back opens. The third type has a round opening the size a cent with a groove which can be turned open with the help of a quarter. I hope this answers your question.

No. I always had trouble popping the back off on a couple of my watches. The tool does that very easily. I can get them back on with a good squeeze but no not a specific tool to do it.

I happen to have a Polar watch that takes this size but I can't say if that will be true for your Polar watch.

Well, since I only purchased the green watch, I can't really speak to the size of the black one. On the watch I got, the band was refreshingly long. With most watches I find I'm using the last hole on the band (maximum length), but with this watch, I'm fastening through the fourth or fifth hole. I hesitate to speculate about what the band length of the black watch is.

I have a x6900 G-Shock which is my biggest watch at 54mm. It fits fine in every spot because of the gaps between glass, but I don't think I could comfortably fit two or three of this same watch side-by-side. I wear all big watches (40mm+) and they fit comfortably.

I have 2 large round watches that are approximately 44mm wide and they fit fine. You should have no problems.

The short answer is "YES"...I mentioned this in my review which is probably buried in there with a lot of others so will mention this again. The watch will accommodate a 51mm diameter watch (except on the 4 corner slots of the case where the lid will impinge on them). The problem is the slots are spaced close together so you cannot have several watches greater than 45mm (that is including the crown) in a row without them touching one another/moving them askew to fit. If you look at the picture the watches are on the smallish side so it looks ok. I would estimate that they're no larger than 35mm (inc crown). If you skip a space between your watches, alternate your smaller/larger pieces, or don't plan to fill it with larger watches it should be fine (of course then it won't hold 18 watches). But if you have more than a few watches and they're all larger, I would recommend another case. Good luck and post a review of what you find.

Yes, it does. It is tricky...be patient while you do this...getting the pins in the holes can be a challenge. One of the holes was worn down and loose and wouldn't hold the pin on my watch. I applied gorilla glue to the band and strap about three months ago...it has worked !

It depends on what you consider "big". My husband and I both have rather large watches with full, round watch faces and they fit perfectly.

Yes, I would imagine so. We got the device to use on my wife's small fashion watch (just barely fit though) so I would think that it would easily fit on a small dive watch.

I used this on my engagement ring, which is on stainless steel. It worked great, I do not know about the glass part of watches.

I think you can use it for pocket watches if you remove the cushioned sections between each watch.

For the chest strap. On the inside is a round access that can be remover by inserting a coin and twisting. Replace battery and replace cover. For the watch I suspect the back can be removed with a jewelers screwdriver for access to the battery. When the battery in mine goes out I intend to let a jeweler replace it. Good Luck, Hal
