I was going through a box of watch parts I got a long time ago and found a lot of little plastic packets with paper backing with a logo of a backwards F followed by an F.  I thought they might be Felsa but I looked it up and couldn't find a match to that logo.  Does anyone know what it represents?   Also, I found a few dozen complete balances.  Some gave movement numbers but others had a strange specification that I don't understand.  I'll post about those tomorrow in hopes someone can enlighten me.  They are in my shop in an outbuilding and nobody goes out after dark on my property.  Too many striped kitties.

The FF was in fact FHF Fontemelon; thanks Watchmaker for the link.  Here is a picture.  So the next question is how to tell the application.  The one on the right has 59 and 59N.  I think that refers to the movement or caliber.  Is that right?  I have no idea what the 3 3/4 refers to.  I'm guessing the numbers below are part numbers.  The left package seems to identify several models under the number 443.  I have no idea what 443 refers to.

I kinda got tangled up in that last reply so this is a continuation.  Here are more packages.  The F appears to be Felsa.  I'm confused about the ST package.  The table I found online said ST stood for Seth Thomas but when I looked at the history of Seth Thomas, it said they made pocket watches until the '30s and said nothing about wrist watches.  So who is ST?  I have a lot of parts like these from several manufacturers.

Let's start with the main nomenclature on the packets.

Top right is the ligne size and the watch calibre from the manufacturer whose symbol is top left. So 6 3/4 - 60 is saying this belongs to the watch of this size and calibre from FHF. A very good resource for checking out watch movements is ranfft. Here's that movement for example: http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&FHF_60

Next is that, helpfully, movement manufacturers normally use a common reference scheme for parts of a watch. Look here for a useful list: http://www.obsoletewatchandclockparts.com/partsmenu.htm. So a '443' tells you this is a setting lever; a '401' is a winding stem etc.

Onto your second picture then ST is not Seth Thomas but Standard; A is Arogno and F is Felsa. 

So with your newfound knowledge you can say, for example, that the ST piece belongs to a 10 1/2 ligne, 1800 calibre movement from Standard and is the centre wheel. Happy days. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&Standard_1800

Watchmaker, you really helped!  That ranfft site is a treasure trove of information!  Also, it appears MrRoundel was right when he said the numbers on the balance containers are the dimensions of the movement.  Apparently they were mostly used on rectangular movements as most of the balances I uncovered do not have them.  Thanks so much!  Dan.

      Epilame / Fixodrop

      Yes, I was referring to the (jewelled) gear train with HP (most of the time, I use 1300, but when Rolex says 1000, I'll use 1000).

      I suppose it would depend upon what your lubricating with those? for instance what does the manufacturer say about those lubricants? I have a PDF from the manufacture and a rather peculiar statement found on the bottom of the chart. my suspicion is the reason the recommending would be without epilam the HP oils like the spread except when they're in Ruby jewel's with steel pivots. tableEN lubrication 2020.pdf

      Is this a 'hack' ?

      By oldhippy · Posted

      These types of hairsprings become weak with age and very fragile. Which I expect it is that giving you trouble, and that wheel is not the correct one, if it were not bent I don't think the movement would run as the teeth are not the correct height. The problem you have is price which depends on you. It can be repaired but is it worth it to you, because there is little value in the clock. A wheel can be made and hairspring replaced. Or hang on to it and keep looking on ebay which is your best bet for replacement parts or even a complete movement but it will be like finding a needle in a haystack.

      I did that also for a few movements - well, mainly in/around the train jewels. I made big efforts to epilame the mainplate WITHOUT getting Epilame into the Pallet fork jewels (where it's not supposed to be, right?). I made litte barriers with Rodico around that jewel and used drops from a syringe to apply on the rest.  However, I've now stopped doing this. For three reasons: 1. It's a hassle and consumes more of this liquid gold. 2. I didn't see the need when using HP1000/HP1300 lubricants and grease for most part. The two places where I'd use 9010 (i.e. escape wheel and balance) receive Epilame in specific places... or the cap-jewel-setting of the balance suspends the oil sufficiently be capillary action (see my "conflict" about using Epilame on the balance jewels).  3. Lastly, and here I really wonder about yours and others' experiences: I felt that applying Epliame to the train jewels left them looking hazy (borderline dirty) compared to the (painstakingly achieved) sparkly clean results of my cleaning process. I just can't help but think that the Epilame residuals would mix with the oil and cause more friction/wear. I don't know.    simple: it'll stay there. It won't move any further. That's exactly what is happening if you epilame a cap stone. You end up placing the 9010 right on top of the epilame and the oil will sit nicely on that spot.
