Seiko 7548-700F Problem Prior To Repair

[jdrichard]

As well, the small wheel that grabs the date wheel does not seem to swing back and forth when you pull out the stem?

Sounds like a worn sliding pinion and also a worn setting lever?

Actually I think you were right. Could not help myself, after snow plowing 6 driveways, my neighbours, I jumped back at it and found that there is a plate that that controls the stem position and this plate has a rail where a small knob from another pivot plate fits. Sorry for the lack of technical terms; I am sitting at coffee and do not have the breakout drawing with me. I had not hooked another keying plate onto a point on the movement and this caused the plate to lift up the part i needed to slide into the rail. FIXED. Tonight I will complete the build.

Back together. Had a hard time putting the hands back on. The minute hand does not to be on in a solid way. Not sure if this is right. If I buy new hands will they fit better . The hour and second hands seem ok. https://vimeo.com/156052865

Well done JD.

If the minute hand is flat, you could tighten it by shrinking the hole by peining very carefully with a round ended punch. Centre the round end of the punch in the hole and tap gently with a very light hammer. Try the fit after tap until it fits tightly. If you over do it, you will have to ream the hole to get it to fit.

If the minute hand has a tube, you can pinch it carefully until it grips.

No tube on these Seiko hands. just s small lip. As mentioned in another thread these usually give no problem after been given a gentle adjustment.

Can you point me to that thread? I just order the new hands. Shame to restore the watch to 98%. I just received the bezel insert and new crystal and will finish with the case this weekend.

Put back together with new bezel insert, crystal, gaskets and the movement completely cleaned and reassembled.

Good job! Have you pressure tested it yet

Nope. Don't have the gear for that. Just dive and prey. I do dive, however I did this for a friend no charge.

If not, be the first water filled Seiko Diver

Any friendly watch technicians in your area with a tester? Someone could do it for free or a small fee i guess?

[jdrichard]

Thanks for the advice Hiren. My next repair is a 6139B Seiko Chronograph. This will really test my skills.

One last thing. The new Bezel insert for the diver snaps in but rotates a bit. Should I glue it down? The last one I purchased to repair another 7548 snapped in very tight. This one will fall out if I do nothing? If I do glue it, what type glue or is their another technique?

Try epoxy:

[jdrichard]

Red or black? Thanks bob

Both actually. They come in a pack and you have to mix the two together. It forms a very solid resinous glue that hardens over a few hours. You can get some quick drying ones that do it in a few minutes.

Like appoxie (pardon for the spelling)

Ok thanks. Just a dab on both sides of the insert I suspect, or you will never get the insert out again.

Yep, just dot it around the bezel, not too much. This stuff is strong so not too much!

Thanks. I'll give it a go this weekend. I am fixing these watches for a friend for free for fun

I love the challenge and the fine motor skill requirements. I also do closeup magic with cards and coins and string. I also play blues guitar. You can check me out at jdrichard01 on YouTube.
