Hi all, Been a while since i posted on here. Drifted away from watches for a bit but now back at it again. Was going through some old drawers and came across a project I picked up a long long time ago that I never got around to doing. It is a DW 6239 w/ modified A7750. Currently it is setup as a PN but I also got an albino dial and hands for it. The hour counter is drifting so I bought a new clutch lever for it as well. Put it all in a box and forgot about it. So upon finding it I figured I should finally get this thing done. I need to pull it apart to change the clutch lever and was going to reassemble with the Albino parts. Where I am having difficulty is removing the movement from the case, of all things. I don't know why it won't come out and I didn't want to force it so thought I would hit up the experts here, in case there was some trick that I am just not seeing. I've torn down and built up tons of watches but this one has me stumped 🤥. If anyone has any advice or suggestions I am all ears 👂 Thanks

They are not interchangeable so stick with the matching movement to what is in your case now. The movements are virtually identical with the exception of the added day wheel on the 2836. The accompanying extra mechanisms to drive it increase the front side thickness of the movement. So when cased the stem position will not line up correctly.

Very nice. Great to have a piece with some history. My dad was a clock guy so I have to start the watch thing for my kids....I think I have a good start

+1. Ideally the length of the stem coupled with the crown travel to de-clutch from the stem would prevent this from happening. However, in the case of most automatics it is not possible to over wind so it really is not an issue. I would not worry about it.

Yup. Need to see the movement. Based on the stem it looks likely to be a DG movement (aka 21j) but not sure. Post up and we can help.

Never been much of a Kawi guy but the H2 is impressive. Enjoy AJ....and be careful

Depends where you live.

Awesome! I love it.

Easiest tell with the exception of a few super clones that are out there is the balance jewel retainer housing. The housing on the ETA has 3 relief cut outs to insert/remove the balance jewel cap retainer. The clone only has one. In 99% of cases this can be used to identify quickly if it is gen or not.

If it were possible I think we would have seen a great rep of the Tudor Heritage Chrono since it would be the reverse swap as described. Quite sure there are a number of dimensional differences that prevent such a swap. Sub dials, thickness, crown position, etc.

Very shocked and sad to hear. He was always great to chat with and very helpful. He was the fuel to my fire when I started out wanting to work on my own watches. In a way, without him, I would not be where I am, horologically speaking. My thoughts and best wishes to his family.

Should be able to sort it out for you. Especially with a new crown and tube in hand. Hopefully the tube will fit the case without much difficulty. Not sure I have heard of anyone yet upgrading those parts.

Very nice indeed. Well done.

Looks like it's wedged in pretty good in the third shot. I will help get it out of there

Rep. What you have there is a very nice example of a clone ETA. The most obvious tell is that there is only one release grove on the balance spring retainer. Gen ETA has three.

Nicely done. Great attention to the most minute detail. Looks like your playing around is paying off.

DO NOT replace the movement! At least not yet. Many quartz movements require a "reset" to be performed after battery replacement. Usually involves shorting the + side of the battery to a terminal marked with "+" on the back side of the movement. Once you do this the movement should restart. If it was stuttering it was telling you it had low voltage from the battery, indicating that it was time to replace it. Based on this I doubt the movement also needs replacing. I would bet it just needs a reset. If you can pull off the movement model number and show a picture I am sure we can get it going.

Could not have said that any better. Truly a one of a kind. Rest in peace.

Balance all wrong, eta marks no good. Clone for sure.

Welcome aboard. Well whoever directed you gave good advice. Great place to learn and gain experience in the rep game. Some interesting prospects you are looking for. Sadly you will be disappointed by the speedmaster.

Hello from down the road in KW

Holy crap!

Far from crude I would say. The result looks fantastic. Really enjoyed reading about something out of the ordinary. Thanks for sharing with us.

Looks like a case clamp screw.
