Had a citizen eco drive given to me by a work mate after he smashed the crystal, I replaced the crystal with a gen from cousins as all was well, gave the watch back, about a month later it came back my way because it was steaming up and the strap was broken.

I had it for about a week where it sat de cased in my airing cupboard drying out for 48hrs  I then re cased the movement and greased the seal and screwed it back together again, just to confirm no steaming of crystal I wore it for a day and got no steaming, gave the watch back today and within 5 hours it's steamed up, not been near any water just steamed up, ive told him to stick it in a bag of rice with the crown pulled for the night and see what happens, can't think of anything else to say or do

I had issues with an older Hamilton which steamed up. Ended up having to fit a new double-o-ring crown and upsized the tension ring crystal by 0.1mm to get a tighter seal. Only then would it pass as waterproof on the Witschi Proofmaster.

I did check and grease the crown seal, as it's just a push in crown and not a screw in one and neither pusher has a screw lock I wasnt happy putting it in the tester and ramping it up to the rather ambitious claim of 10 ATM water resistance, i,ll be honest now, due the fact that there are no screw down parts I didn't put it in the tester. I might see are out the crystal gasket and enlarging it by that amount, its just puzzling me as to why it didn't steam up for me but has for him

Same happened with me the watch above: fine for me, but steamed up for someone else. It’s hard to know what might cause it, but it may be related to the air expanding and contracting within the case.

Well overnight on the radiator with the crown pulled and work all day and it never steamed up once for him today, might well of sorted itself out, who knows, but I will keep an eye on it just in case it does it again.

      Bracelet Adjustment Puzzle

      By HenryNorton · Posted

      I'm struggling to find information on adjusting a Seiko bracelet. I can pull the locking pins out but the links remain very much together. I don't want to bend anything without being sure I've tried everything. Anyone else adjusted one of these?

      Full plate watch, Suitable tool for adjusting & testing pallet stones?

      By JohnR725 · Posted

      I was thinking it might be nice to see a picture up above or the picture I'm going to paste down below from up above with the escape wheel just setting their. Then it almost looks like the lower jewel is out quite a ways? But maybe it's an optical illusion with the shellac yes the assortment set over time have become something other than what they once were. Like it work with a assortment of Waltham jewels for burnishing in and the last time I tried to find one I discovered there all randomly assorted. Then of course often times the assortments had a tiny quantity of things and the entire container got re-tasked for other things and down the road somebody sells it totally clueless of what they're selling. But in the case of roller jewel's especially after the longer ones of pocket watch size for a single roller then randomly and bottles is definitely good. If you really careful you may be able to place the roller jewel on a flat surface and use calipers although a bench micrometer really is preferred.

      yes the pocketwatch database shows quite a spread in those serial numbers. With the watches typically made in batches and even in a batch from the beginning to the end there be some variations. Then you have approximately a 10 year difference between the two yes some of the stuff will probably not fit especially escapement components as there usually adjusted at the time of manufacturing and of course manufacturing tolerances were improving with time. https://pocketwatchdatabase.com/search/result/elgin/36764469 Grade:    315    Model:    3     Class:    114   Estimated Production Year:    1937  Run Quantity:    4,000     Grade/Model Run:    310 of 329 https://pocketwatchdatabase.com/search/result/elgin/19110954 Grade:    315     Model:    3     Class:    114    Estimated Production Year:    1917   Run Quantity:    2,000     Grade/Model Run:    127 of 329

      Argh. Breaking pallet pivots

      By Poljot · Posted

      Hope you let the mainspring completely unwind before removing the bridge? Use not only a screwdriver, but a pair of good tweezers with curved ends. This will allow to move various sides of the bridge straight up while keeping it in parallel with the main plate. If you use a screwdriver only and top pivot is stuck, then a bridge is being lifted under angle and then you hear that "horrible click". Usually it takes only one instance to learn such lesson in life 😅
