Had to get new winding stem to an Omega cal. 342 , beacuse not original crown.
Got an replacement from Ronda, but does not fit.
Tried to fit the stem yesterday, but Im not able to get in in right in the movment.
The original just go right in every time, but the new Ronda stem will not go properly in.
Are there anyone that have some ide why this not fit?
Can the notch in the stem where I have put red arrow have somthing todo with this??
Its slightly smaller on the Ronda stem... se photo
i wonder if anyone could offer some advice. I have an Omega seamaster 1345 quartz day date. Working well. However it seems the date is stuck (as shown in pictures) i know the push button at the 4 o clock position is meant to filter through the date? However when pushed in nothing seems to happen. As a result of this the watch works fine but only up untill 11pm it doesnt turn over to midnight and therefor change the day or date. Minute hand works perfectly but it seems i have to change the hour position every morning.
when i turn the crown, hour hand moves fune and after the 12 o clock position changes the day, but date does not moth along with it.
anyone know how i can resolve this safely without removing too many parts of the movement?
Good evening everyone. I am new to this forum and i can see we have some outstanding experts on the site.
brand new to watch repair and looking to get some advice. I purchased an Omega seamaster quarts 1342 watch (not currently working and not tested) as it was a bargain and understand that 329 is the equivalent of the original mercury battery used when the watch was manufactured?
I am hoping the battery change will mean it is functional but in the event it does not work, how easy/costly is it to repair. (I’ve heard parts can turn this bargain into a money pit)
would anyone in this community willing to have a go at fixing it after i try battery change?
paid service of course.
any help advice would be much appreciated
The only markings on the movement are the words Swiss Made, 15 Jewels and a small 5 under the balance arm. I don't currently have a very accurate caliper but I think it is 34.7mm rather than 36.4 as the Unitas 6497 movement wouldn't fit. Here is a picture of the dial side but I haven't seen any writing on it. I do not believe that the movement has ever been changed since it was made in around the 1930s.
I have a nice little carriage clock in for service, very good shape, except for over 0.30mm sideshake of the barrel arbor in the barrel. Thought I would show how I bush these; it seems they often get overlooked or just skipped as they are a little more fussy than just bushing a plate. I measure everything up, then remove the boss in the barrel, and make a bushing that fits from the inside and is stepped, replacing the boss. This way it's captive, and doesn't require a big interference fit to get seated and stay. I turn up the bushing with a boring tool in the lathe, doing the outside as well (running in reverse of course), then do the barrel opening with the same tool. It's a pretty quick process once you have the moves down!
Well the movement is Unitas, but they did make many many different calibers. What is the exact diameter of the movement, and can you get a pic of the dial side? Are there no markings near the balance cock or on the dial side? If not it will take some digging but you will probably find it on Ranfft's site.
I must admit I have never even clapped eyes on one like that, but my gut feeling is that you back off the key in the opposite direction to winding, and it will unscrew, then undo the knurled bolt, and pull on it, and *something* should slide out of something else.
The chances that I am completely wrong however are around 50%
EDIT: Wow.. Barographs are expensive when new.. https://www.metcheck.co.uk/collections/barographs
. I'll need to keep an eye out for one, they look pretty interesting, similar to clockwork seismograph recorders .
Thank you but I should have mentioned before, tried a Unitas 6497 clone movement to see if it was the correct size. The gears are far finer and the escape wheel teeth are the wrong size and it was slightly too short.
It has a Swiss Lever escapement as far as I can tell and is about 4.5mm in height. If it helps the mainspring barrel is the size of the winding gear on the top and seems to be fully attached to it.
