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.

      Pivot Gauge

      By Neverenoughwatches · Posted

      Den / Dennison is a unit measurement of size this is actually a mainspring gauge . I haven't heard of a pivot been measured in Dennison before.  Though the small thickness gauge is  usually supplied with a Jacot tool and is more accurately known as a pivot destroyer.

      Pivot Gauge

      By Waggy · Posted

      Could it be an abbreviation for Denier? "Denier (/ˈdɛniər/) or den (abbreviated D), a unit of measure for the linear mass density of fibers, is the mass in grams per 9,000 metres of the fiber. The denier is based on a natural reference: a single strand of silk is approximately one denier; a 9,000-metre strand of silk weighs about one gram." The pivot gauge looks interesting, however I wouldn't trust myself to drive a pivot into a wedge incase it jams and gets damaged/snaps trying to get it free. More a comment on my ability and incompetence than the quality or design of the tool 🤣

      Cleaning solution clarification

      By BObsagat · Posted

      As I've seen multiple posts here about multiple types of cleaning solvents, I've done little more than confuse myself more thoroughly that I was before. To see if I understand things correctly... 1.  Is One dip is a solvent which is a cleaner and also a protective rinse for hairsprings jewels and pallet stones only? Or can it be used on all the parts (like the case and wheels and all the things) It seems like that would be much easier as it's just "one dip" but it is very expensive. 2. Isopropyl alcohol is a great cleaner for manual cleaning or ultrasonic cleaning (only enclosed jar) just not on pallet fork as it may loosen the shellac holding the stones. Does it have to be 99%? 3. When buying a small manual cleaning brushes, does anybody suggest a certain material of the brush itself?

      I am new to the new to the watch restoration hobby I have the basic tools. I'm here to learn new things. And utilize my resources (you guys) to expand my knowledge and hopefully save some derelict timepieces from the trash.
