My First Strip Down - Helvetia


PhilB

Recommended Posts

Wow, what a fascinating thread, and very encouraging (despite the lost screw). Perhaps get a stronger magnet, one of those neodymium monsters?

 

My first strip down will be of a virtually identical watch! I haven't started yet because my tools supplier forgot to include the Bergeon screwdriver set :-( The most expensive item it was too, mutter, mutter...

Its back in the case and running fine.

 

I'm very pleased with my first strip down. I've lost a screw and crown ring washer but all in all a good result.

 

Has anyone else stabbed themselves with an oiler? They might be thin but they're **BLEEP** sharp, my thumb is throbbing.

Highly recommended (the storage)! Great job Phil, and on your first watch!

 

What happened to the crown ring? (You are talking about the bushing I believe). Did you sourced another one?

Not the oiler..... but stabbed myself on the forehead with very pointy tweezers, whilst trying to catch a loupe falling out of my eye ......... TWICE ........... :(

That's so annoying when that happens: the tweezer points get bent out of shape when they hit the bone :(

 

Pro Tip: try not to poke them in your eye instead though. The eye is much softer, so the tweezers will be OK, but it's not so good for the eye.

Phil your doing great. I'm reading along and see you're getting excellent help from everyone. Just keep working steadily and taking those pictures! You'll definitely need them as reference later when you reassemble. Great work so far!

    • Next is to drill the screwhole this then provides an anchor point so the bridge doesnt slip around while scribing the shape. A cork lid, a pin and a piece of gaffer tape ( 😅 ) keeps it all in place. The hole is measured from the broken part using a hand measuring gauge. Mark the hole, punch it and drill it off to size. The awkward bit is working out where the jumper should be and the detent positions.  I remember watching a youtuber a while back do this with dividers, so i dug out my old school compasses and improvised a little. This bridge only has one hole and to find the detent positions you need two points of reference, so i just worked the second point from one of the corners, hopefully its near enough. Then scribe in the jumper using the two detent positions ( wind and time set ) that were marked and a big picture of the complete spring to look at that helps to give you a feel of where the jumper should be. 
    • Right now I'm making do with a similar micrometer (the one below is $45 shipped but you can find better deals) and a $20 stand. You do have to be excruciatingly careful measuring jewels, since there's no table, but if you don't have the $500 to throw around, it's a nice option.
    • As  I kid, I'd watch Godzilla stomping over buildings and cars and I'd think to myself: Tokyo is a really dangerous place to live... . Cool watch!!
    • Next one up an AS 554, looks like a bit more to this one. First job is to check thickness, most springs are somewhere between .3 and .4, this one measures .35, that matches in with the .4 spring steel i ordered. So for marking up a permanent marker comes in handy to colour up the steel to be marked later with a scriber once its dry. Bestfit provide the extra bit of info for the jumper spring that is missing.
    • Thanks again, Marc.  Super helpful. I was wondering what the hole was for, and now it makes perfect sense. With your help and the other members here, it looks like I'm good to go with my Seitz tool set. I had to order some replacement pushers, but with those, the set is complete and in good condition. Now, I need to figure out what tool to buy to measure jewels (amongst other watch-related parts). I had my eye on the JKA Feintaster micrometers, but people get crazy bidding on them for $400-600 USD. I was thinking of just a regular digital micrometer (Mitutoyo). Thoughts?  Mahalo. Frank
