    How close is the Asian 7750 clone?

    Well that is fascinating, Al, and thanks much. I was always curious about this situation, and you have provided answers I've not seen anywhere else. Thank you so much for explaining, and going through the trouble of posting the great shots for demonstration. All the best, Rich.

    How close is the Asian 7750 clone?

    Well thank you so much! Your tip led me to the Seagull ST255, and from looking at images I believe this watch has the Seagull version, with the engine turned decoration, and other detail differences. And from what Al says below, and from what I've been able to look up after your tip, I am...

    How close is the Asian 7750 clone?

    I'm working on an "homage" to the Panerai Submersible 44mm PAM00025. It is actually surprisingly close to the real thing, and very well put together. The version it is copying is this: Panerai Luminor Submersible 44mm Mens Watch PAM025 PAM00025 The copy even has the "hobnail dial". In any...

    Tissot T-Touch Classic- resistor detached?

    Thank you for the tips, Fire. I didn't take it out to test... was quite pleased the other end was attached, and didn't want to mess with it more than necessary. Now it is necessary, so... A couple of electronics friends suggested these are capacitors, not resistors as I thought. Not sure...

    Tissot T-Touch Classic- resistor detached?

    I soldered the resistor back to the board (ugly joint, but I think it flowed), but unfortunately it still does not work. This could be because: 1) My soldering worked, but there is another problem, such as the resistor is cracked, or other problem like the board trail/connection is broken where...

    Tissot T-Touch Classic- resistor detached?

    I was writing on another thread about this Tissot T-Touch Classic T083420A Tide/Alarm/Compass watch I bought on eBay. Now I think I discovered why it does not work. I thought this may be of interest... especially if it turns out I can fix it. The watch has an ETA E49.301 movement. This has dual...

    Tissot T-Touch Tide: Missing Module?

    Thanks much, Skutt... I also found the manual, and other information, so I'm all set now. Proto.

    Tissot T-Touch Tide: Missing Module?

    Watching that video solved the problem with the watch, also: The last owner must have lost the clear, insulating disk shown. I only needed to cut a new disk, with contact slot, for the base of the battery compartment. It works now, but it seems to need to be reset, or like that. Anyway, it is...

    Tissot T-Touch Tide: Missing Module?

    I may have found the answer to my own question: The T-Touch "Race"... or "T-Race"... seems to use the same ETA E49.301 movement. And the T-Race also has no air/water pressure sensor, and also has a tide function, both the same as my watch. Well this battery replacement video for the T-Race shows...

    Tissot T-Touch Tide: Missing Module?

    I took a chance on this Tissot T-Touch "Classic T083420A Tide/Alarm/Compass" on Ebay. It was sold as "non-working", but hoped I may be able to fix it. Of course that is a gamble, but I've had very good luck with various quartz watches... most needing a reset or jump start and so on. Anyway, on...

    Mido pressure tester cylinder problem

    ... I thought of another thing I may try, but not today: I could machine a soft steel drift to fit from the top. I could drill, tap, then split the end first. Then after it is in the compression cap, insert a screw to enlarge it, thus wedging it into the compression cap hole. Hopefully it would...

    Mido pressure tester cylinder problem

    "Can you get a knife edge..." No, there is no gap at all. I didn't want to assume, so I checked again, carefully, at your suggestion. I can get to a small gap under the screw holes, but really nothing large enough to wedge it apart can fit in there. I tried tapping in one of those cheap mini...

    Mido pressure tester cylinder problem

    Thanks, Karl... actually I did have the hook and plunger out when trying to get mine apart. I only had them back in for the above picture. Well it just figures, then... our units are differently designed! I'm going to take a wild guess that your's is the improved version. In your design, when...

    Mido pressure tester cylinder problem

    Thanks again, Karl. Whenever you have a chance... if yours comes apart easily, at least we could see how the internal parts are shaped, and I'll know better how to get it apart. All the best, Rich.

    Mido pressure tester cylinder problem

    Karl! Thanks for getting back to me. The part that is stuck is the one I've labeled "seal compression disk", because I suppose it squeezes the O-ring or seal in the cap. That is the part stuck in there. I can take out the screws no problem, but the disk won't budge. The thing is, if I knew...
