I just serviced the 7009 movement from a 7009-3170. I haven't put it on the timegrapher yet, but it's keeping decent time from last night.
The crystal is trashed, and the case gasket fell apart. Stem gasket looks iffy. I've tried searching, but I can't seem to find any information on this particular case. I've found a bunch of pdf's that claim to relate to Seiko cases, but somehow, I'm just not finding what I think I need. So, I have questions:
1. Does anyone know how this crystal comes out? I'm hesitant to just put it on a press and push, though that might answer it.
2. Does anyone know the crystal size? Getting it out, I could measure it, but I'm not quite there yet.
3. Where is the best place to buy gaskets? I've not done that yet, so this is new territory for me.
Thanks in advance.
Thank you for the greetings!
my watch was gaining around 2 min a day when I set it then waited 24 hours so something is definitely wrong or broken.
I did think about that, but kind of wanted the 7s26 to keep things original. I thought it would be cool to keep the non hand winding and hacking although it isn't the most convenient haha! If I do a modded skx then the NH36 definitely something to consider.
Welcome, as an aside, if I was replacing the movement in a SKX007 I'd swap a new NH36 in instead of an old 7s26. Apart from the advantage of the reliability of a brand new movement you get the bonus of hand winding, on top of the auto and hacking. What's not to love for about $30?
