47mm 605 Crown Issue - Advice Appreciated

[Woundup]

I will try not to go into an overly detailed post... I sent 2 605's from different factories to a watchsmith that I had used a couple of times to see if the movement/dials could be swapped (one had a much better dial, the other had a much better case shape). It was not possible, so he put them back together and shipped them back. I ended up giving the 605 with the lesser dial to a friend and kept the other.

Fast forward a few months and only haven worn it a couple of times.... I go to wind / wear the 605 and the crown would not assume a 'locked' position in either date change, time set or secure to the case - there is a resistance when I try to push the crown in. When the crown is rotated, the only thing that happens is the hands rotate as if I was setting the time.

Sent it back to my watchsmith for evaluation and he tells me that it needs a new crown - the 'spring' has lost tension and will not engage the stem properly... Sounds plausible, though unfortunately he's not providing much help in sourcing a suitable replacement, so I'm trying to figure it out myself. FYI - he has been great to work with and fixed several issues on other Panerai / AP watches for me. He may just be too busy.

So doing a little research I found this crown from the same resource that makes the strap spring bars I recently bought - they state that this crown will fit a 47mm:

I greatly appreciate input or direction from those here who know....

PAM605 and date setting? What is your watch? Which factory? 605 can be ZF / SF with P.3000 clone or V6F with 6497, but none of them have a date.
I won't tell you what the problem is, but the device depends on movt.
Unless, of course, it's really not just the crown.

If it is necessary to buy a crown, it is better to take it together with the stem, then it is more likely to install it yourself.
To select, you need to measure the diameter (I don't remember it), and find out what kind of movt you have, the type of stem will depend on it.
If this is a 6497 crown then you can go to getat, Jackson, helenarou, dsn, or eBay. Most likely, these two main indicators will be normal. The subtleties of the crown shape will be observed 100% only if you buy a crown somewhere from this particular factory, which made the watch, but in general, they are similar.
To accept the force, you can adjust the position of the faceted screw on the tube at the base of the crown.
This will help compensate for the difference in its thickness (crown), if this difference exists.
Finally, if you have a clone version, it also uses one of the existing stem standards, but I don't know which one for the p.3000 clone. I think there will be participants who know the answer to this question, if they themselves were engaged in repairs.

Ugh... Sorry, I have several watches in for service and I mixed them. Obviously no date on the 605.

I believe this to be the ZF Q series.

No problem, I was just surprised. If it is zf, then there is a clone of p.3000, and I do not know, unfortunately, which stem it uses, as far as I remember, it is not 6497, but I will not argue.
I think the one who served p. 3000 will soon come to the discussion and answer exactly how you should proceed.
Nevertheless, it seems to me that the stem of this clone is unlikely to have a thickness greater than 6497, and in this case, it is always possible to screw the crown, suitable in shape onto it with a seal and a retainer.

Hi mates, on p3000 clones, stems are thé same as on 6497/98 .
I have had a faulty SF p3000 on a pam372 that i swaped for a 6498 with no problem, it's a straight swap and i used the p3000 stem for the 6497.
Here it could be that the stem has'nt been properly reinserted and secured with thé stem release scew as well as it Can be an alignement default. What you Can Do is contact one of ours trusted watchsmiths and see with him for advise

Here, if anything, the issues of attaching the crown to the rod were discussed. When you buy a crown, if you decide to attach it yourself, I think it will be useful:

Thanks for the replies and links to past fixes....

We are going to try this one - from the same seller as the nice spring bars I had posted about previously.

Will report back if this works or not.
