1971 Caravelle Diver With Resin Case

[hubcityvintage]

Hey guys! I recently acquired a 1971 caravelle diver with a plastic resin, one piece case. Entry to the movement is through the front. I removed the bezel and crystal thinking that I could just remove the hands and maybe the dial would come off exposing the keyless works. However, when I lifted the dial I was able to catch a glimpse of the edge of the movement and I could clearly see a dial foot screw. It it possible that I have a two piece stem? Does it just pull out with some force? I don't want to break anything, but would like to clean and service this watch as it's been sitting for who know's how long! Any help would be appreciated. The movement looks to be a hand wound bulova 7089. I checked ranftt but didn't see any info. Have you guys seen this before?

Before exerting brute force, try turning the stem around a little at a time just in case it is two piece with a slog that will allow the movement to drop out when you find the correct position.

If that doesn't work, then brute force is more than likely required to remove it. I have not worked on one of before and these are just my thoughts. I hope someone can give you a definite answer.

I have never worked on this movement before but from the picture on the right, I can see a small "space" between the dial and the case @ 3 oclock. I wonder if it is some sort of ring that holds the whole movement in the case or simply a small gap to get to the setting lever somehow...

Thanks for the responses guys! I saw that in the pic too, but it's just a reflection of some sort. No space there on the actual watch. Geo, I thought about that and attempted to free it that way yesterday, with no such luck. I read somewhere that someone used a cannon pinion puller to pull it out as it allowed them to use the least force necessary to do the job. Maybe, I will just look at it a bit longer first. It's keeping great time, but I want to clean and oil it!

That was me taking the stem out of my Tissot.

Haha! Of course it was! Great idea by the way. I have a really old puller that would work great for that kind of thing. I'll let you know how it goes.

Nice watch .Looks like a Tissot Sideral . Have one of those . My stem can be pulled out with some force . Doesn't have a split stem .

Didnt Mark show this in a video. The one he used compressed air to pop off crystal to get to movement?

I think that was a Omega dynamic

I think that was a Omega dynamic

I meant the technique of pulling the half stem not the watch.

[hubcityvintage]

The compressed air trick is cool, but still scared me a bit! Especially on older watches.

Also, I was thinking that this watch was put together like a sideral and that the stem would just pull out. Problem is, I can only be wrong about that once!

I have seen someone use a plastic bag and a plastic syringe . The plastic part of a syringe not needle . Placing the bag over the pendent tube and then the syringe over the pendent tube . Press some air in and pop .
