Hi everyone,

I would like to introduce myself; my name is Fabz and I have recently started watchmaking as a hobby.

I am excited to join this group and learn this art from the more experienced members.

I would like to service 2 women manual watches I have just bought;  the first one is a Bulova (movement 5 BA) and the second one is a Nobellux (movement ETA 980), but I am struggling to find the service manuals. I wonder if anyone from this group can point me to the right documents.

Thanks in advance.

Fabz

Thanks for the introduction and welcome to WRT @Fabz ! 

I'm stalled partially through my first watch movement restore due to waiting on oils and tools (all of which should be on their way).

At this point I still don't have a network of resources to draw on and that's one of the great thing about places like this: it's filled with information.

I have several Bulova quartz watches and suppose I should start looking for a mechanical one.

Thank you for your introduction and welcome to this friendly forum.

We all look forward to your contributions and continued involvement. 

The Eta 980 you can download from here

Bulova 5BA from here

Thanks for the reply and sorry for my late reply.

Unfortunately the ETA 980 in Cousins is a quartz movement, while mine is mechanic https://17jewels.info/movements/e/eta/eta-980/ . It looks like ETA named 2 movements (one mechanic and one quartz) with the same name?

According to Rannft the ETA 980 is a a 1940 approx. mov.t, back then there was no such thing as the service manual we have today that show exploded diagrams, what lubricants to use, etc. That is because watch repairers were supposed to know their trade well, and that kind of info was trivial for them.

So, all you can find is an illustrated parts list, for example on Cousins UK for the ETA 1010, which is very similar to all other of same age and type.

I see that JDM beat me to most of my answer. the unfortunate reality is every single watch does not have a detailed service manual. If you can find anything at all usually you'll find just the parts list. That's because the watch companies perceived that whoever was working on a watch new how to work on a watch they did not need a detailed service sheet. The day when we start getting specialty lubricants we are seeing more and more individual service sheets but they just didn't always exist. Then even today sometimes I have consolidated sheets with a take a grouping of watches and only have the things unique will be  covered. Then they maybe have separate instructions for lubrication or cleaning  or whatever and will probably never see those anyway because the watch companies today don't like to share.

then the 980 is an interesting movement in that it is a mechanical. The quartz are usually a 980 with a decimal point and some other additional numbers to differentiate them sometimes.

      What's your thoughts on this Rolex Sea-Dweller, ref. 16600, calibre 3135 project?

      By VWatchie · Posted

      Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.

      Help with repairing a quartz clock

      I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.

      Id love to see how he has the output shaft mounted to this setup, as I have the same rotary stage and stepper in my build.

      Broken watch stem in watch crown

      By Poljot · Posted

      If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem.
