It looks pretty old. Also I'm struggling to find anything by FHF that size, and with matching keyless works. It is a bit of an odd ball.

Remarks
FHF ran several factories in Fontainemelon, and one was named after the founders Fabrique Robert. The calibres produced there are recorded in few registers (pretty poor and contradictionary) under names like Font Robert, FF Robert, FHF Robert. Bestfit mentions the Gruen 103 as an FHF Robert 8.75''' downsized to 8'''. But the example here (from a Wilka Watch) demonstrates, that this size was available right from factory. Obviously the 8.75''' calibres Gruen 100, 101, 620...623, 626, 627 are also based on this calibre, and are accordingly listed here, but realiable informations can't be given here.

Swiss Patent 51482:
filed 05-03-1910, FHF, Fabrique d'Horlogerie de Fontainemelon (CH)
setting mechanism without setting-lever spring

Example, year: signature; shock device
ca. 1925: - 9686, +51482

That is also similar, but the keyless doesn't look right.

I think that the serial number is 32746 on the barrel bridge.

I've just finished trying to identify some scrap movements I bought. I think this is an FHF 1146.

The keyless looks the same. Though it measures 23.3 mm

In the flume catalogue i have the 1146 came in sizes 8 3/4'"   9 3/4'"   and 12'"

1180 ? The 80 accidently  double stamped

I'm trying to find a balance staff for it.

It looks identical with the FHF 1156 from Andy Hull, only that this is 15J. and 9-3/4 ligne.

I wonder if the staff will fit.

Do you have the staff to measure up ? Balance staff . Com list an fhf caliber 119 at 9  3/4'"

I need a balance spring and a pallet fork for this movement. Any idea where to find it?

On the dial side of the watch is stamped FHF8, but obviously this is a variant of FHF 1156 (different bridges).

Your only real chance is to find a donor movement on eBay.

Different bridges don't mean fork and balance springs are different too. 

 Fork and balance are parts of the escapement, designed to beat at certain rate which the entire escapement is suppose to produce, so you should base your search on beat/ frequency of the caliber you have .

As clockboy suggest your best chance is to find a donor, or a balance complete.

Balance spring off of two new balance completes of same caliber & frequency  won't readily interchange, though can be made to produce the design beat.

Prior to mass production of balance complete, watchmakers had to vibrate balance & spring to build a balance complete. 

There many discussions on the subject on WRT forum.

      Standard crystals to replace tension ring crystals

      By ColinC · Posted

      When can you use a standard crystal to replace one that had a tension ring? The first time I popped a crystal with a tension ring out of a watch I found that I had a suitable sized standard crystal and decided to try that.  It fit nicely and it was hard to see that anything was missing from the watch.  I understand that it probably reduced the water resistance of the watch but since it was an old dress watch it wasn't going for a swim anyway! I have since tried the same thing on another watch and found that the tension ring seemed to have an additional role of holding the dial in place.  With the standard crystal in there the dial and movement falls forward. This means it rattles in the case and falls forward and the hands fowl on the crystal (when the dial is down). Is there a trick I am missing here or does this watch require a special crystal?  I am reluctant to buy an expensive armoured crystal only to find I have the same problem.

      So I wrapped the anvil it in bubble wrap and passed ot through the demag only. Still no go—the unit is simply too strong.  next experiment is to use a VARIAC to lower the voltage and see if that reduces the magnetic field.

      Need some crystal replacement advice

      By VWatchie · Posted

      In this case, the underside of the crystal is flat so I assume I don't have to worry about clearance to the hands. However, perhaps I'm missing something. If so, please let me know. I guess no one has the patience to get into the details of my first post so here's a simplified version of my question: The case diameter for the glass gasket is 36.9mm. However, Cousins doesn't have a glass gasket with that diameter. The closest are 36.8mm and 37.0mm. Would any of those two options work, and if so which one? I have no problem ordering both and testing them, but If someone already knows it is pointless, there's no reason to order. No, I haven't. Is there someone you can recommend? Preferably in Europe. Thanks!

      Dangerous substances when disassembling timex indigloo?

      By rjenkinsgb · Posted

      No. It's incredibly volatile and evaporates in seconds; there is no way it would last as long as it took to just install the part cleaned in it, in the movement.

      404 Club Reboot

      By ColinC · Posted

      When I record how much I have spent on each watch I include the postage.  UK EBayers seem to be charging £5 minimum these days on postage.  Have made a couple of job lot buys recently - based on the average price this one could be 404 reboot project  Bad photo from eBay - 1 of 4 watches for a total of £21.19. A Medina with an MST 385 movement - Soaked in oil but looks like it will run again!
