Cheers Bob,

 

I will post a picture of the innards when I get it apart. 

 

Unfortunately I have to prep the front door and surround for staining tomorrow.  Its supposed to be good weather if you can believe the forecast and it needs doing before autumn sets in. Wire wool is the order for the day ho hum.

Hi Vic, I wish you well with both projects, I know what one I'd rather be doing. I'm away to grout rough surface tiles today, and I'm definitely not in the mood to do it!

It rained everything is masked off outside and only one coat on - is it me or are the dates on the postings showing November ?

Yup - the forum's showing November - that's why it rained when you wanted to do your outside painting. Mark's fixed the weather as well! :D

Well I can't do owt outside so I took the back off. 

 

The Movement is marked - Brevets, Swiss Made, 17 Jewels Unadjusted Buler Watch Ltd., BFG 158 31/7. 

 

The spring is hanging loose at one end.

 

The time is displayed on three disks and the seconds disk was rolling around in the case but the other two are firmly fixed and can be changed with the winder.  There are two small apertures on the minutes disk that presumably are used in some way to remove same but one thing is for sure normal hands lifters are not going to fit but a home made tool is likely.  It looks like the inner side of the crystal has been slightly scratched so I am going to have to find some appropriate matching black paint that is not going to lift any of the good stuff off.  So spring problem and crystal to attend to and disc removal so I can clean it after dismantling.  The good news is the steel case which is dirty but in quite good nick considering.  Here are the pics.

what are the missing parts?

I may have a suitable donor in my parts/projects box but if the missing parts are specific to the jump hour function then I know can't help as all my spares are for conventional hands.

Downloaded the PDF for parts from Cousins and it seems that there are some bits missing :thumbsd:

That's a bit of swine, let's hope Marc can help you with what you require. This is what I like about this forum, the way folk are willing to help one another.

Hello Marc,

 

I am still investigating but the spring is not attached at the outer end and if you have a quick look at the photo there is nothing to attach it to or that it has been attached to.  I am not familiar with this movement at all but on others I have worked on there was a + and - on the cock and an adjuster and this one seems totally without.  It is quite interesting i found one article here - http://watchguy.co.uk/service-repair-buler-baumgartner-bfg-158/ . It may be a pin pallet movement - new to me.

I see the problem, the whole regulator assembly is missing and I would guess that the hairspring is probably not too healthy either.

 

I have done some rummaging and your in luck. I have a complete and running (albeit in need of a service) BFG158 in a Buler which should provide any of the going train parts that you need. Dial side will be different though as it is conventional 3 hands and a date but with any luck you don't have anything missing from that side.

 

It is definitely a pin pallet (or pin lever) movement, this one with 25 jewels, so quite an interesting movement to work on if you've not come across one before.

 

Anyway, this one has you name on it if you want to pm me an address.

      AS2031-57E solar panel - mission: impossible

      By Albyon · Posted

      Imm going to close the discussion by attaching the photo of my super-titanium after several vicissitudes finally working. Purchased as not working I replaced the battery and for a stroke of luck I found its semi-new solar panel which, having verified its operation, seems to recharge the accumulator perfectly. I had taken this watch almost by bet, with 40 euros I brought it back to life. The initial half idea was to resell it to finance another purchase, but.. it's definitely a nice item. It would need to check the impermeability but it's a pleasure to see it on the wrist 😃

      Insert the movement inside the case

      By Albyon · Posted

      In fact the secret is to go gently and find the way without forcing, and the movement enters without problems

      Epilame / Fixodrop

      By VWatchie · Posted

      Sure! Some very accomplished repairers never use epilame! I have often wondered if it is worth the trouble. Not using epilame will shorten the service intervals though, but that could be better perhaps both for the owner and the repairer!? Speaking of oiling, I just read this: After WWII in the 1950s the first Synthetic Oils came on the market. Most watchmakers did not rush to use these oils since they were bad for business now that the watch serviced with Synthetic oil would not come back to him for service for another 5-7 years he would lose a lot of income. ~Ofrei.com   Anyway, I wouldn't be surprised if it would be more correct to think of epilame as a binder rather than a repellant. Until convinced otherwise that's how I will think of epilame.

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      I read that same article last night  H.  I think epilame is too much headache for me, sources aren't always accurate, some conflicting. Such is the GRAVITY of this situation, Is it ok if i just STICK  to a thixotropic oil 🤣
