Vintage sea king rotor problem

I bought a vintage bulova sea king automatic at a antique mall for 80 dollars and I discovered the reason for its lower cost. It appears that it was someone's project watch that they sold. It has a 11 Anacd movement and the rotor is stuck. It can move but it grinds against the metal underneath it. The middle portion of the rotor(with the engraving) is loose and moves independently of the rest of the rotor. I have no clue how to remove the rotor as there are no screws on it. Is this a deeper problem than just the rotor or can I fix/ replace the rotor?

Update: I removed the movement from the case and the plastic retaining ring snapped as it was very brittle. The movement holder was keeping the rotor from turning freely. The rotor is two parts and each are press fitted together. I put the watch back together and the rotor now spins freely. It does worry me that the rotor may fall apart again so is there a good way to keep the two parts together?

One of the problems of watch repair is that even though watches all looked similar there also different. So for instance two parts impressed together means I have to try to use my imagination because you didn't give us a picture which would've been helpful. So I'm assuming you're talking about the center part of the weight pressed into the way to itself?

Then I don't suppose you have a timing machine?

Then as I suspect it will be helpful I've attached information

Now that we have a tech sheet the work with let's start over? The automatic weight is held in place with a gib which is held in by a small screw removing that the automatic weight should come off as one piece. I making the wild guess you pushed it together in the watch and yes it will fall apart again.

One of the things I was looking for in the PDF on the parts list is not there? Some watch companies like Omega assumed that the automatic weight might wear out and had replacement components. But according to the PDF the axle has been welded to the plate and that would have to be replaced if that wore out the entire unit. Then it looks like the weed itself is considered one piece. So my guess is the pinion That looks like in your photograph is probably steel Reese the top part is came undone from the Weight and that is not a separate component. Which means ideally you should replace the whole thing. Or taken apart and see if we can friction fit it tighter together I'm assuming it was friction fit perhaps taken apart and use a small model Loctite.

Then I have a link to the parts list which should agree with the PDF but usually does not sometimes there's more parts available or potentially had more parts than the PDFs will show. Like for instance the axle which we know is welded to the plate and not available separate does show up as a separate part on the parts list below which of course you can't get. I was kinda hoping that the automatic weight came into pieces but it does not so if you replace it it's one component unless you can push them together and they stay together.

Then the reason I asked about the timing machine was that the stud holder and regulator don't look like they're in the right place except? The second link is a picture of your watch and it looks like they're in the same place. A lot of times if people were in the watch which typically the knot in wristwatch because usually it's too hard to get the back off if they do get in the watch they do like to move the regulator around.

      A lathe with indexing that won't break the bank?

      By coreymsnow · Posted

      Excellent info, thank you! So when you say "conforms to the standard" does that mean, for example, that parts are interchangeable between brands and ages, or that you could use accessories built for that 110-year old one on a newer one that was built in the 1990s? Also, thank you for taking the time to answer my questions and your patience.

      It was first a brand, but became a standardized style. So you will find some older lathes actually marked "Webster Whitcomb" and many other makers who built WW lathes conforming to the same dimensions for spindle height, bed shape, attachment setup, collet size and design. https://www.lathes.co.uk/derbyshire/ So when someone mentions a WW lathe today, they are talking about any lathe that conforms to the standard, which could be a 110 year old American made lathe or a European made lathe from the 1960s or something else.

      Timetrax

      Hi guys, just a little thank you for the CLOCKBARN site in America.  I purchased a TIMETRAX APMLIFIER to help with setting clocks in beat from CLOCKBARN it arrived on time and when tested worked ok.  A week later I had occasion to need it again, this time nothing the unit was dead. Checked out batteries , probes etc , nothing.    I messaged CLOCKBARN  to this effect.  I got a prompt reply that he would send a replacement which duly arrived today and having tested it it’s ok.  So I can recommend the site should you need to use it. The person,persons who run it are genuine guys.  So thank you CLOCKBARN  for your excellent service.

      Timex M33 - A small repair

      By mbwatch · Posted

      Hi there! You have learned how professional watchmakers feel about Timex. It is very difficult to find one willing to work on them, for a few reasons: 1) a lot of them wrongly believe Timex cannot be serviced, are riveted together. This is a myth. 2) when serviced, they still cannot meet the performance standards of jeweled mechanical watches (-20sec/day is good enough for a Timex) 3) customers are unwilling to pay the watchmaker's hourly bench rates because the watches are worth very little The service manual for the M33 is available at https://heritage1854.com/m33 but you also need the M32 and M31 manuals because they build on each other (31 is the base, 32 has date, 33 has day and date) https://heritage1854.com/m31 https://heritage1854.com/m32 A stuck date changeover can be due to a missing, bent or broken detent spring (part 2576 in the manual) or the date wheel (2556) got stuck or separated from its post, or maybe disengaged from the hour wheel. With a little confidence, these are not difficult to repair and parts are pretty much interchangeable with any other Timex from the same era having the same features. So it is very easy to find inexpensive spares in the form of junk watches (don't bother trying to search for individual spare parts). My recommendation would be to find a junk Timex with an M25 (older manual wind with date) and practice a little with it. Follow the service manual from the same website. The automatics are a bit more difficult to work on but once you get a feel for how they fit together, you can make an attempt at your automatic and you would be able to use many spare parts from the M25 if necessary. To work with most Timex movements, you do not need a lot of tools. Just one screwdriver, 1.4mm is a good size, tweezers, and hand levers to remove the hands plus hand pusher tools to replace them. Of course if you want to do a full cleaning and restoration more is needed. But to get it apart and diagnose, only minimal tools.

      I do indeed have some programming and electronics know-how. 3 decades writing code for a living, and playing with microcontrollers as a hobby. 🙂 It helps with my actual living of being a voice actor because I can maintain my own equipment- no one around to replace the caps or the tube in an obscure botique mic that isn't made or supported any longer. Also saves money maintaining and cleaning my own interfaces and mixers when they develop problems in the faders and such. That said... I do have a question that, I'm sure, will betray my ignorance about certain areas that I have yet to fill in. I understand a "WW" lathe is a "Webster Whitcomb", but from what I understand that is a style of lathe and not a brand, correct? If someone would be willing to clarify and maybe expand on the terminology, it would be helpful so I can better understand the advice being given and know what I need to look into to further my knowledge. For example, a Sherline mill would appear to be either a separate piece of gear or an attachment/expansion to their smaller lathe. When you say you have a WW lathe and a sherline mill, can you say exactly what devices you have? Thank you! (I just realized I have a few Raspberry Pis and some Arduinos of various form factors around here I could probably put to good use in a scenario like you describe above).
