I have a Seiko 6458 diver with a circuit board damaged by a leak. Looking for a replacement circuit board or entire parts movement with a known good circuit from either a 6458 or 6433 movement. I'll pay a fair price depending on what it is. Thank you!

I'll cut right to the chase: I've been googling for an hour and can't seem to find a parts sheet for the Cal. 944X movements, or any other place to find part numbers. I have a 9943A that needs a coil. Jules Borel lists it as " X/9582" but that doesn't seem like a Seiko part number, and anyways...

Hi everyone, I am learning about the 7548 and 7C46 movements. I see where some claim the 7C46 is an all metal movement. I have seen one and I know that is not true. Are they confusing the 7548 with the 7C46? Also, why did Seiko replace the 7548 with the 7C46? From what I understand after...

I apologize if this has been covered before, but I was unable to find anything here. I have a quartz ETA F07.111 movement where the hands shift depending upon the angle of the watch. Only the hour and minute hand shift slightly (say about 30 seconds worth of movement). This doesn't happen when...

Hi SCWF, A quick question; what lubricants do you use on quartz movements? (Seiko 7548, etc). I've rebuilt a handful of C300s and I've got one that was literally soaked in WD40 that needs servicing (the previous owner sprayed the whole watch "liberally" with it to free up a stuck pusher which...

Recently got this one after looking all over for one in a decent condition for quite some time. Reading how, for whatever reason, people like to buy birthyear watches I was interested to check watches that were released when I was born. As I was born in the mid of the Quartz crisis (as Swiss...

Attention quartz movement experts: what kind of signaling is coming from the chip on a 7a28 to drive each of the 4 trains? Is it just pulsing the coil in an alternating polarity to ratchet it forward one tick? I'm familiar with larger unipolar steppers like you'd have on a 3D printer, but was...
