case back

Hi guys I have a scratch on the glass case back of my Hamilton 38mm American Classic (you can't see it too clearly in the photo, but it is visible and irritates me). I've tried contacting Hamilton customer service with no luck - I want to know if I can buy and replace the glass (not the whole...

After buying my Aquis which I was told had a sapphire case back by Oris boutique London and the sales people in the shop I bought from, I kept seeing people say it is mineral. Also some online stores say it's mineral. Some reviews say it's sapphire. Well it's mineral. I totally missed that on...

I have had this Citizen ecodrive watch since new. I typically change my family's watch batteries but this one has me stumped. It appears to be a snap caseback, but I cannot find a spot to insert my Bergeon caseback blade. Please see photos. Any help is greatly appreciated, thanks.

I hope this is the proper forum for my post. If not, I apologize. Back in the day--when I was not as educated nor discerning when purchasing vintage watches--I bought what I believe is a 6139-6002 Seiko Pogue (I do realize the 6005 is considered the actual Pogue). One of my issues regards what...

Hey everyone, I've never asked anyone, but have noticed over the years that probably 50% of people make a compound word out of "caseback" while others separate the two. I really have no particular opinion and have, I think, subconsciously gone between the two of these. On one hand...

Hi, there have been several posts related to the (in)famous DO NOT UNSCREW text on the case back. However, nowhere I could find what really is supposed to happen when you remove that screw. I mean, will the stem release instantly or does the tiny hole give access to some pusher for releasing...

Hey everyone, thank you for taking the time to read this. I've been trying to open the case back of this Citizen ana-digi vintage watch from 1970. I figured it was a screw in back case, but no matter how hard I've tried (I do have the appropriate tool), it just won't budge, which got me...

Hello, I have never found removing a case back to be a chore, but today I am left with a bit of annoyance. Each case back grove is less than perfect. There is no place for the tool to grab because each grove has been worn down. Small bit of alcohol has been used, hot/cold. I assume there is...

Hi all, I have a question regarding display (or, exhibition/see-through) case backs. So far, I have not been able to find an answer! I’ve got a sarb035, it is a great watch, but the hardlex crystal in the case back has got quite a few scratches on it. Is it possible to replace the crystal in...

Comrades, I bought a Poljot on the bay and when I took the back off I was greeted by this strange circle of vinyl -- WTF! I can't imagine this is how it came from the factory, or why it's there, it can't be for water proofing (at least not vinyl). My only guess is perhaps there was a rubber...

I replaced the battery in this watch (it's a simple watch but has special significance for me), and cannot put the case back on. It requires such tremendous force that I am afraid to break the domed crystal. Can anyone recommend basic household tools (that I would likely already have) to put it...

Hello everyone! I'm a newbie watchmaker and have been buying many non-running vintage diver watches to learn and maybe even rehab some of them. I just came across a beautiful diver. The stem and crown came off when I tried to set the date. It goes back on and works well, I figure the locking...

Recently acquired a 145.036. According to the seller it was serviced by Omega in late 2013. The dial, hands, crowns, and pushers were replaced and it had a complete movement service. All the original parts were included with the watch. So, I can return it to its hard won, original quadragenarian...

Hi Guys, I have this beautiful chronographe suisse 18k from the 50ies, it has Landeron 148 or 248 inside it. Originally it had two covers, one “dust cover” in copper and one outer cover in 18k gold. Mine is missing the outer gold cover. When i wear this watch for a while and take it off, it is...

Bought this 1960's Nivada watch on eBay. Works well on the Timegraph with nice clean lines so was very happy with my purchase, but then noticed the hour hand is out of sync with the minute hand. Missed this totally on the photo from the listing shown here. Problem is, how do I open the...

Hi all, So I'm looking to buy this watch, for sure. (Unless one of you can talk me out of it.) I'm a grad student in Physics, so I'm looking for something that can go with a nice button shirt all the way to a full-on suit. I want something I can wear more often than not, so that means...

Hello, Once again, I am asking for the help of this forum's great community :): Has any of you seen this caseback type before? it is a "snap-on", but it is rather unusual, I think... It belongs to this watch: The caseback looks like it is made of solid gold (!!!), but it is rather...

Hi - I am considering buying a vintage '65 Speedy that shows corrosion on the caseback (not the case). Should I pass or is the caseback (i want a seamonster, not stamped medallion) something I can easily replace? if so, where can i find one? Thanks!

does anyone have information on thread sizing for watch case backs? I have gathered that commonly the pitch is .5mm. Is this correct? is there any information out there or formula about how to come up with the Fit and dimensions based on the other diameters? thanks

Hello, I have stumbled across this watch and there are a few things that don't seem to add up -the all stainless steel case has a shape that I have not seen before-in combination with the dial -the case back ring is too "broad", normally they are a lot narrower What do you think?
