You will need some tools like these to do that and be safe,I can't get the hands back on ???
I tried to search info on this model and it takes me to this thread and previous on the crystal. Are you sure that's the model number? Well, does it have the crown on the 3hr marker or around the 4hr marker?
well it all depends on what the dial is from....they should have little pins that come out...if the dial is from the later 7s26 you will have to remove the pins and use dial dots or have new feet put on...you just stick them on the spacer other wise it will not allow the movement to work properly as the day wheel will move the dial...the hand reinstallation is quite easy..most people use a hand setting tool...i have even used the small screwdrivers with the end removed and put a small amount of tape over the end to protect the hands and do them one at a time...you need to make sure the day wheel is just changed over to the next day so it is at midnight so it will be accurate too....if you have any questions feel free to pm me too...God Bless John
