Hi guys,

I've had this Felca Automatic for a while and its been a bit sluggish so I thought its high time it a service.

One area I wanted to fix was the date change was not 'snappy' and it seemed that the corrector was not fully home after midnight as the date would not centre in its window unless you have it a sharp tap.

Turned out the date wheel is a bit worn so the problem remains. Date wheels for the 2452 are available but for the date at 'six' not so much.

Here's some pics.

Its hard to see in the pic below but it reads 41 jewels on the rotor!

A bit plain but the date at 6 gives it some character.

Basically a typical ETA watch, well designed and produced. One thing I did was to tighten up the clearance of the rotor. This is a plain bearing design which screws from underneath. The screw forms one bearing surface and the rotor the other. By reducing the height of the post on the rotor you effectively close/tighten up the bearing surface thereby removing play. You can only do this a few times ..sooner or later the rotor will hit the bridges. If you're trying this..remove small amounts at a time. Too much and the bearing will be tight.

      Movement inserted from crytal side

      Before putting it back in the case I would fit the hands and use a pin vice on the stem to make sure the hands were in line.

      Put the movement in a movement holder and it will be supported as you push down on the setting lever post to release the winding stem. Make sure the post is over the shoulder of the movement holder so what you are pressing down on is supported. As a general rule, hold the movement and not the movement holder. Replace the hands when the movement isn't in the case and support the centre jewel (if it has one) on a hard surface or staking block when replacing the hands to stop the jewel accidentally moving or even coming out. A dedicated movement holder with a central jewel support is even better, but pricey

      It might help us if we knew which watch like model number.

      Movement inserted from crytal side

      By Zedster · Posted

      Hi, guys I have a bit of a predicament and hopefully, somebody can advise. I'm working on a Roamer MST 521 where the movement is extracted from the crystal side. I'm now at the final hurdle where I need to replace the movement back into its case but I'm not sure of the correct procedure. I still need to fit the hands but that's where the problem lies. If I insert the winding stem to test the hands for correct alignment I will need to turn the movement over to release the stem again it's the spring-loaded type and needs a small bit of force to push down but with the hands fitted, I don't think I can do this on a cushion without causing some damage to the hands and that's the last thing I want to do, this watch has already been a love-hate relationship and I'm so close to boxing this one off which I'm counting as my first major project.  The other option is to case the movement then fit the hands and hope everything is okay. I've already broken the original winding stem but managed to find a replacement, the last one in stock, so I'm a bit reluctant to keep removing it. Any suggestions would be appreciated.
