FHF Robert 8.75 Ligne


AJH

Recommended Posts

Hi I am new to this forum and am looking for a balance staff (or balance) for an unnamed movement, the only markings are the Swiss patent number 51482 and a serial number 4903.

It is a manual wind, no seconds, I have trolled through Ranfft and think this may be a FHF Robert 8.75 ligne, can anyone shed any light on this and where I may source parts, ebay and Scotwatch don't seem to have any.

Thanks

Alasdair

Hi clockboy, I have searched balancestaffs too and they don't have the FHF Robert listed for 8.75 ligne so I will need to go with your suggestion and measure the old staff. I don't have the tools or experience yet to replace a staff so will have to take it to a watchmaker I guess.

I would still like to know if my movement ID is correct...

Thanks for your reply

I think your identification is correct ... in which case this FHF Robert is the same as the Gruen 100 / 101. This takes a balance staff with the Ronda number 1144.

If you go to the Cousins page https://www.cousinsuk.com/category/filter/ronda-staffs-by-ronda-number you can search for balance staffs by Ronda number and I see they'll do you a pack of 12 for £8.95. Worth searching other suppliers too.

Alternatively if we're pretty confident with the ID and now knowing that your FHF = Gruen 100 /101 (which also according to ranfft are the same as the Gruen 620, 623, 626, 627 as differences not known between these six models) it could be worth a search on a site like ebay for any complete movement going that has a good balance.

Hi @Nucejoe ... if you let me know why you've left a 'confused' emoji I'll try and clarify! You may want to look at http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Gruen_100 first though.

It won,t let me choose the emoti I like, sometimes I get to choose the medal other times the confused emoti or one of the other choices.I mean approal by all and the point the post gets. Sorry thats the best I can do and that is despite rather costly , paid vpn service. Sorry Sorry.  You did ID the movement, the one point is my thums up.

Best regards joe

By chance I found this on ebay which is pretty lucky, it is on it's way from New York as I type, fingers crossed it is the same as mine.

Thanks for your help, really appreciate it guys.

    • Welcome to the forum Dan, enjoy.
    • H Watch Repairers—is there is a ‘standard format’ for the service marks or codes lightly engraved inside cases of pocket watches or wristwatches?   Sometimes I can see there might be a reference to year/ month but other times am confused. I’ve included an image of the rear of a 1951 Hamilton 992B Railroad pocket watch as an example. Thank you for all information you can give, Mike
    • Hi to Blackminou29–am a collector/ caretaker—good luck to you following your repair course—with hindsight I wish I’d pursued a career in both watchmaker/ jeweler fields—good luck with whatever career passion you engage.   Thank you Watchweasol for posting the amazing TZIllustratedGlossary! Best wishes, Mike
    • yes I noticed the new site and I miss the old site. It's the unfortunate problem of the Internet here today gone tomorrow sometimes some of the stuff gets backed up and sometimes well it does not then the problem with the early Seiko's were there were not necessarily designed for distribution across the planet and as such there is no customer support for them. So trying to find early stuff like technical information or sometimes even parts list for older Seiko is is problematic. But I did find you a you tube video. A quick look he seems to take a heck of a lot of time to actually get to the service single I did not watch all that but it does look like he did disassemble or started to say there's a tiny bit here
