Question: P3000 super-clone movement. Follow-up to cali 448 question.

[jakeslatnesky]

Drawing from the assumption that most of our learned colleagues have lives and better things to do than entertain questions, I have one follow-up question on a spring issue with P3000 movement on a California 448, Z-Factory. Sead is the TD (and I trust him implicitly).

My first post indicated that the P3000 used to wind to "resistance" and I would carefully wind it to full stop. Never overwound it, usually allowed 2-3 days for winding. I found the spring skipping as wound it. I could feel it skip. Then during winding, it seemed like the entire spring just zipped back to zero. Now, I can wind it and it keeps time but it will just wind to infinity. I can wind it all day long and it won't stop. Question: does the P3000 have a clutch that prevents it from being over-wound? Or does it actually have a stop where the spring is fully wound. I would be grateful for an answer if anybody knows.

Final point: The TD has agreed to take back the watch, send it back to Z factory and have them either repair or replace it. I'll be happy with a replacement movement but then I'd also be happy with a Mercedes CS500.....

The spring on a manual wind movement can only be wound so far, after which, the coil will refuse to be tightened any further and so the crown will not move. I don't have a PAM with the gen P.3000 but I have never read an article that would indicate that it differs from the superclone P.3000 in at least how it winds. When you said you can wind it all day and it won't stop, in that situation, does the watch work? Being able to wind endlessly means the coil is probably not being wound and as such the potential energy is not being stored in the coil from the stem.

That's it. That answers the question. The watch is acquiring some power as it has been able to hold 24 hours of PR on say, 300 winds. But it no longer stops at full-wind. I can wind it all day. Even though it keeps time, I will make the most of my warranty and try to get it repaired or replaced. Maybe Z factory will simply throw a new movement in there. Thank you!!

Send it back to China, it is hard to find Asian P3000 replacements for rep friendly watchsmiths. So may be, this time, the best option is to ship it to China.
