Hello, I'm new here. Never repaired a watch before but hope I can muddle through this one . I imagine a professional repair would cost more than the watch is worth. The stem on this watch broke. I have both pieces. I removed the remaining piece of stem from inside.( took forever ) The movement says Ronda, but no numbers. I think the crown might be permanently attached or at least very tight.
I really like the watch and hope someone can help me fix it. Thanks!
I received the attached ladies Longines watch, around 33mm. It has missing a caseback that needs replacing. I believe the model number is on the missing caseback. Anyone could offer some advice on how I could identify this in order to be able to get the right caseback replacement?
First watch job as a novice watchmaker, I bought this Longines Cal 12.68z 1969 at the flea market as a scrap, and its shows jerky movement on the second hand skipping like 5 seconds every minute. The hands don't look right and the dials ... I leave it as is. If not for the Longines logo.. I can't identified this watch without opening it.
On disassembling found it was the escape wheel that was damage, it's an old watch so I guess it's in pretty bad shape to start with.
Ordered from ebay, and it took along time to reach me.
Replace the wheel and one thing leads to another, on installing the click spring, the tiny screw decided to take flight. Ok I was using cheap tweezer, that remind me to get a good sets of tools. In the mean time I just dressed it to ensure no more aeroplane job for those many more screws.
No way I could find that screw, it's the smallest of the smallest in this watch. So back to ebay and ordered a box of screws as I found some discussions about it here.. so another 2 weeks of waiting and it finally arrived and lucky me.. there's one that fit.
BTW I did not dismantle the center wheel, I feel I am not up to it yet. Looks like it pressed fit and I don't dare to touch it at my present skill level.
It was over oiled and very dirty, I do not have a cleaning machine (yet) so a simple dip cleaning and some tooth pick will do for now. Assembling apart from the aeroplane incident goes without anymore surprises, just that I need to horned my skill and getting better tools. The balance wheel and pallet is a challenging part to me and all else is okay.
I use Chinese made oil as lubricant at the moment and lube all the jewels, not reaching Moebius or Novastar level yet... so it more like Mario Brothers at level one... had to earn points before I go up scale.
So here it is, nothing special it's a basic movement as a start, and I have lots more watch to do as practice pieces.
On the wrist, hey.. this watch is older than me... I'm 53 and this old timer is 56 years old.. :)
One thing I learn from this first job is... I need higher quality Screwdrivers and Tweezer for a start... time to get the credit card out.. I can't find high quality tool here in Kuala Lumpur.. most shop do the Chinese brand.. will try to get either A*F or Horotec sets.. a basic set will do for now. Suprisingly after 24 hrs.. running no further adjustment needed.. it's keeping good time.
There is a slight problem with some of the citizen movements . They seam to be to large distance between the gears for the second hand pinion. Bad explain but hope you get in anyway.
That makes the second hand stutter. Nothing you can do. The lever spring you can get to by taking of the rotor bridge.
