This just came in client said watch keeps stoping. This is what I found. date window frame on dial is loose hitting hands and loose movement hold down screw jammed against barrel. My question is I can't seem to find the stem release pin. I'm so used to working on swiss watches Help

I'm attaching an image Snipped from yours. There are two places the first light blue circle that's where the  release pin would typically be. Which I'm assuming is not what it is but that's where it would be if it existed.

Then the light pink area nothing is there exactly what the image shows? Except sometimes on Seiko watches and this resembles a Seiko watch the release only becomes visible when the Watch is pulled in to setting.

Neither of those even looked at that lever looking thing in the top rhs corner.

[thewatchdoctor]

Now I suppose someones going to say its under the rotor plate

[Nucejoe]

How do you plan to get the screw- barrel unjammed?

Some Seiko but which ones? On the current 7S / 4R / 6R and I assume many others the release point comes out with the stem fully pressed in.

A quick search of google says it is derived from the Seiko 4206.   Added pusher for Day setting. 

[bklake]

Now I read that it is a derivative of the Seiko 7006.  That makes more sense based on the size of the movement.  The rotor does look like the 4206.  I have never messed with a Seiko 7006 so not sure how they compare.

My bet is on the lever.  Just ran across a similar system (Seiko) in a front-loader.

[thewatchdoctor]

Once I removed the movement case ring it became obvious when I pulled out the stem to its furthest position. The hidden lever appeared almost like a puzzle box. The big lever btw is for the quickset day even though there is no pusher for it on the case. This set up is contrary to all my experiences with Swiss watches where you push the lever before pulling the stem. JohnR725 was right.

A bit more delving and I found out on 17jewels the cal 46493 is a smaller version of the seiko 4206. A more recent version of the same caliber looks like the citizen / miyota 8203.

Pull the crown to the hand setting position, I think that a lever should appear next to the stem to push and remove it.

 

EDIT: Oh! I see you already found it

Next question watch is running and second hand moves but hours and minutes don't. Hours and minutes turn when setting the time ?

This is a classic problem with canon Pinions. If the canon pinion has too much slippage then the hands do not move but they will move when you set the watch. Then because the secondhand is independent of the setting parts that's why it will continue to turn. When you're trying to set the watch does it feel super loose?

Then can we have a picture of the case back I want to look at the numbers found on it?

[thewatchdoctor]

Cannon wheel was loose. The center wheel end is flush with the jewel looks like it the end has sheared off in the cannon pinion. Must of been a hell off a drop. Would explain the loose screw and the date window frame. I know the owner does enduro / motocross which might explain it. Now to search through my broken seikos to see is anything fits I know Ive some seiko 5 seven series.
