FHF 909 Movement..Date change problem


Recommended Posts

A recent Garrard purchase reveals the date starts to change at midnight and then flicks back so does not actually change. Would this be wear on the date driving wheel part of which seems to be plastic or nylon. Also is the jumper the wrong way round. (Wrong side against the spring) Any help would be appreciated Thanks...

Hi most likely wear on the wheel.  The jumper looks ok, was it like that when you removed the dial.    What’s the movement make and calibre. Usually found under the balance or on the plates,   Maybe able to get a service sheet.

It is an FHF 909 movement. The jumper is exactly as I took of the dial but found a pic from 'The Movement Archive' which shows the jumper the other way round

On this picture the jumper is upside down (I mean the last picture). On the first picture the finger on the day wheel that switches the date seems short, and on the last picture it is normal.

 I have a bunch of fhf 9** series, note that fhf 905 got date disc too.

Should be careful not to lose quick date gear thats on the stem, so little easy to lose hard to find replacement for.

    • Most all my 404 candidates are coming from swap meets and "antiques fairs". One more $4US plus battery and elbow grease. Unnamed digital on a decent ss bracelet. Gains 10 seconds a day so not that accurate...
    • I voted.for the 6.99 assuming £, which works out to $8.74US at the current exchange rate.
    • £4.04 originally worked out to $5, or thereabouts accounting for currency fluctuations. Inflation calculator from 2020 (when the thread was started, though not when Andy coined the term) says we're looking at $6 currently. What currency is the 6.99 inflation adjusted figure cited in the poll? $6 may still seem restrictive, but don't forget that's part of the point. It's a challenge. Thrill of the hunt and all. Diamonds in the rough. Also, and my personal angle on the game, a fun and inexpensive way to learn watchmaking skills.
    • Dear all My first experience servicing a quartz watch after servicing as an hobby my mechanic watches for many years. This is an old Certina that was given to me by a friend, with  a ETA/ESA 9362 movement. Before service I put a new battery and the watch was working. After servicing the movement stopped working. i understand that there might be a lot of reasons for this (including the fact that I used technics and oils from mechanic movements on this one  ), but at this stage I would only need to check if the electronic module is good. Don't have a quartz tester but only a multimeter. You will see on the photos that the battery contact is broken and needs soldering. With the battery in the movement I can confirm that the electronic module had power (1.57v). Question: what basic tests can I do with a multimeter to confirm that the electronic module is good? how to check if the coil is good and if there is pulse in the electronic module? what contacts should I use to test it? (I saw some videos on you tube but was not able to find the specific test procedures for the ETA 9362). Any information to help me check if the reason for the movement to stop is on the electronic or mechanic part of the watch is much appreciated. Many thanks
