Default 7002-7039 crown issue

I have just picked up a 7002-7039 pepsi from post office just to notice that the crown spins freely and doesn't catch the threads. When pulling out the crown it looks like the stem itself doesn't sit properly:



I know that without removing the crown+stem no one will ever know what's wrong but before I do this I would like to ask for some basic information regarding the 7002-7039:

Does it share the same crown+stem with all other 7002 variants?

Anybody aware of a source for a NOS crown+stem?

Does the -7039 share the same case with the other 7002s (apart from its bezel click spring)? Just in case I need a replacement case due to damaged crown threads...


That being said it's pretty nice...





Thanks for your help.

I always thought the 200m 7002s shared more with the SKX Divers than the 7002 150m ones... The crystal is different as well.

It’s 70E11 NS1. I have it if you can’t find it.

Yes 7002 7039 does use the same crown and stem as all other 7002 divers except the 7002 7010. Cousins list the same part number for the crown/stem for the SKX 007/9 too.
The 200m case is different to the 150m case, you can however use a case from the 7002 7020/9 if its the case tube thats the problem.
Another work around would be to swap the case over for a 150m case, but you would need a 150m bezel because the click systems are different.
The crystal from the 200m case will fit the 150m case but you will need to use a Sterkreuz LG325314 gasket, as it is a smaller diameter than the 150m crystal, though i have no idea if it will pass a pressure test.

Many thanks for all replies. I'm going to start with a replacement crown+stem (@Acidstain PM sent ) and hope that there is no issue with the threads/case.

Just a quick update:


I have ordered a replacement stem+crown assembly 70E11NS1 which arrived today. After replacing the old assembly with the new one, the crown now screws down properly and everything works as it should. The old stem was bent.


I would like to mention that the Ebay seller immediately refunded me the amount for the replacement crown+stem, which I very much appreciated. Very pleased now and I really enjoy this little 7002-7039 on its folded bracelet:
