well a working p4000 movement would be a massive improvement,i will wait for someone to get their hand on it and give us a complete report,please make it works,i have doubts,but hopeful .
okay am so sorry about that... i think that the 620 is one of the best pam also luminor due steel, but in this case the putted on the wrong movement and wrong dial..
Now i would ask you what you think about this hand winding movement, is it reliable? pam512 is not that bad actually!
