I have found the same issue. Maybe the only way forward is to service the movement or take measurements and see if you can find a match using the Cousins catalogue. Here is its tech sheet.

THANKS I WILL TRY THAT.

found a working mvmt on e-bay from Japan ? at a decent price so will replace with that then take the original apart and see what happens using your useful data sheet. thanks again B.

as stated took it apart, transferred the good parts and now its fine At the same time my friend gave me a Rotary quartz to fix and i had to search for a Miyota  4T43 to replace a 4T48 (or vice-versa) (i forgot which!) and had to fiddle around as the sub second at 6 was higher up the face than the original but i got there in the end! i am becoming quite adept at these quartz movements as i never fancied tinkering with them before but its another string to my bow. B THE SEIKO is the second set of pictures (me idiot)

If you pull the crown out to the setting position does a little tab pop out of the side of the movement?

If so, and especially if it has a little dimple in it,  try pushing down on that to release the stem.

    • people be honest.... Swatch is evil for the watchmakers and repairers, BUT not everything in watches from Switzerland is from the Swatch-Group. As far as i know, Selitta got sacked by Swatch as a Movement-Assembler for them and they started to produce Movements in their own Name with slight Modifications. As far as i know, they sell Parts to the Market for their Movements. In most cases, if a ETA-Movement fails, it is a valid Option to replace it with a Selitta Movement, which i consider the Solution for this Mess with the Swatch-Group...... I have no Connection to anybody at Selitta, but being a Swiss-Guy, i still like to have Swiss-Made Watches, but not from the Swatch-Group.   ok ? regards, Ernst
    • Just one more greedy act by Swatch. They started a number of years ago here in the US..cutting off supplies to watchmakers that could build complications that many Swatch houses couldn't even touch. Old school masters who had gone through some of the most prestigious houses in the world. Otto Frei has some statements on their page about it. I tell all my customers to avoid new Swiss watches like the plague,..unless they just want an older one in their collection that still has some parts out on the market, or they have really deep pockets and don't mind waiting months and paying through the nose to get it back. Plenty of others to choose from..IE Seiko,..or other non-swiss brands Even a number of Chinese brands are catching up with the Swiss,..and I think that in time, their actions will be their downfall
    • Yes. If that's not what you are experiencing...start looking for something rubbing. A 1st guess is that one of the hands is rubbing against the hole in the center of the dial. Especially if you now have lower amplitude in face up/ face down positions.
    • Once a movement has the dial and hands put back and it is recased, would you expect the assembled watch to have the same amplitude as when the movement is in a movement holder and is without hands and dial? Thanks
