I recently reacquired a watch I had swapped off to a friend years ago, a Seiko 7t62-0am0 Asymmetry (I believe was the name). The watch is a quartz movement and is a chronograph. When I initially bought the watch (new) it was worn gently. When I traded off the piece it was to a dear friend who tucked it away in a box and essentially forgot about it until recently. I got the piece back a few weeks ago, had a battery installed at an AD and it worked normally. After arriving home, I put on the watch and it was functioning normally, except it stopped after about 30 or so minutes. I took it off thinking it was a faulty battery or connection, but when I looked at it the next day in the display case it was again working. After repeatedly wearing the watch and removing the watch when it would stop, I have come to believe that my body heat is causing some metal part to expand, thereby making the watch stop. Could this be the case? If so, what exactly is the issue (i.e., which part is the culprit)?

Thank you in advance for your assistance.

Got quite a peculiar one at the moment, and it's something that I've never personally encountered before.
The clients watch is an Armani AR5905; he thought he needed a new battery and so here I am,
Upon taking the case-back off and placing a new battery in, I heard the circuit do the all so familiar whirring noise like it was springing back to life, however when I flipped it over it wasn't ticking.
So I pulled the battery out and again put it back in, but what I noticed was that the whirring noise was only happening when the battery was halfway seated and thus not making full contact, and as soon as the battery was fully seated everything ceased. This time I put the battery in halfway and then flipped over the watch to see it working, and to my surprise the seconds sub-dial at the 6 position was spinning around wildly. However again stopped when the battery was fully inserted.
Anybody have any ideas as to what is going on?
I could upload a video if that would help.
Hello to all,
My name is Ash (from NZ). Im a watch enthusiast and trying to learn more about Horology.
I have been picking odd watch repair jobs here and there and self-learning.
Firstly, thanks a lot to Mark Lovick for uploading fantastic videos on youtube that are so simple to follow. Keep up the great work
Question - is there a way to diagnose quartz watch circuit using those test probes (that have an LED inbuilt) or perhaps using a multi-meter? For some watch movements such as Myota 2035, it makes sense to replace the whole movement. In other cases, it make sense to repair it (if possible).
Is there a way to narrow down the faults in quartz watch? For instance, if a watch is gaining/loosing time, it could be the quartz crystal out of freq etc. how can it be scanned appropriately?
Im not sure if its even possible or not. Hopefully I could get some help here.
Thanks a lot in advance
I have a watch I would like to fix my self. It's made by TAWATEC, who is no longer in business. It's very similar to a Luminox and used TGS for lume. I will provide information to the best of my ability.
Here is a link to some information about it. Here are a few pictures of the watch.
I have had the watch since May of 2011. I had the battery replaced in Feb 2015 by a local shop. Less than a year later, I noticed that after taking a shower there was condensation under the crystal. I pulled the crown and left it sit to air out. After about a week I pushed the crown back in and the watch no longer worked. I wondered what caused it to leak. I then remembered I had to change the date on the watch a few days before condensation had got inside the watch. When I was trying to set the date I noticed that it was difficult to pull the crown out and it was more difficult to turn than usual. My guess was that the gasket/O-ring that is on the stem/crown was messed up and had ripped and water had entered that way. I left the watch sit for a year and used another watch as my daily driver. I'm hoping to get this one up and running again. So I recently decided to see if I could fix the watch myself.
Here is what I have done and have figured out so far...
I was able to remove the case back by removing the 4 Phillips screws. Visually inspecting the O-ring that seals the case back, everything looks good. The movement is a Ronda 515. The plastic ring that holds the movement inside the case says Ronda 515 # 6. I was able to remove the crown and stem. Looking towards the inside of the crown there was remnants of the O-ring. After clearing the remnants and putting the crown back in, the crown moves freely. I also found remnants if rubber on the front of the dial. After inspecting the battery, it looks to have leaked its electrolyte What I would like to do first is replace the O-Ring that's on the crown and put a new battery in it. If I then determine that the movement is damaged, I can replace it later.
What do I need to do to figure out what size of O-ring I need for the crown? I can take pictures of the crown/stem if needed. I also have analog calipers to use that are in inches.
Thanks for your time!
It's my first post here, please excuse if I post to the wrong sub-forum.
I own a small collection of quartz and automatic watches and at least do most of the usual service myself.
A friend of mine gave me an old watch she likes and asked me if I can change the battery. She told me it's around 25 years old and cheap but she likes the dial. It was a present by a french bank she worked for.
All my watches are either press or screw down backs and I have never seen a watch like this. It seems that the only possible way to open the watch is the small plastic notch on the back. I tried to open it with quite some force but it didn't open.
Do I overlook something, is there a special way to open it?
I also got the original case. A note in it says in french that the battery is interchangeable.
Already thanks for all your help!

Unless you have another watch you can steal them from, it will be hard to say that they are "screw x". You should be able to get those from a normal fastener supplier though. You just need to know the thread pitch, diameter, and length of the screws. You can measure the thread pitch with one of these: https://en.wikipedia.org/wiki/Thread_pitch_gauge Note that metric and imperial systems measure screws differently of course, so if you're having trouble getting something that is exactly right, try using the other system. Googling around should get more details on getting the right measurements.
I have the above watch that has four small cross head screws holding the back of the case on. My question is that these look rather worn so where are places to get these screws and what measurements would be needed? The pic is not the actual watch but is the model. TIA Mike
