A tale of two watches. (7T32 content)

Recommended Posts

Last year, I picked up a blue 7T32-7F70 to go with my yellow one. I bought it cheaply as it was advertised as non running and I thought all it would need was a new battery, but in the end, it was totally kaput. So I waited patiently for a working one to turn up, and last week, one did. It hung around for a while with no takers so I put in a cheeky offer and it was accepted. At this point the pair have cost just £40. Now it was a case of taking the best bits from both and making one good one. The cases and bezels of both were pretty fair for near on 30 year old watches (one dates to 1991, the other to 1990) with the usual odd scratch here and there, commensurate with age. Both crystals were good, but the working one had a bent crown stem and the piezo alarm disc on the inside of the caseback was worn away in places so it was hit and miss as to whether it worked...when it did it was very faint. Both bracelets were pretty badly scratched up and the one I kept would need refinishing.

These are the two watches with their bracelets.

The one on the left is the working one, the one on the right is the duffer...it's also missing its minute hand from the sub at 9.

Both bracelets are pretty much the same...really scratched up.

So out with both modules...both crowns have to be removed first. To remove the main crown, pull out to the first click and press here...

...and to remove the alarm crown, pull out to first click and press here.

Now the module can be removed. This is the duff one so I'm not being too precious about laying it hands down...normally this would be the other way up.

Next, the bezel comes off...pretty filthy under there!

All the bits I'm going to re-use now go into the ultrasound cleaner...this is before switching on.

...and after the cleaning cycle...yuck!

Time to re-assemble. First the bezel spring and 'O' ring are lightly greased. I now use one of these 'Lubriboxes' to grease gaskets...it's so much cleaner that trying to smear grease on by hand, and it applies just the right amount...

It has two sponges impregnated with grease...you just pop the gasket in, close the lid, give a twist and it's done. They come with various different greases in them.

Bezel and rehaut back in place.

Working module back in, with the unbent crowns and caseback from the non worker so the alarm sounds correctly.

I chose the best of the two bracelets and got to work with a Scotchbrite mop in the Dremel, then finished with a green Scotchbrite pad. The re finished one is on the right.

Here it is with its yellow sibling...

Finally, I have one, nice, working watch. Now I just need to find a black one to complete the trio!
