Hamilton 12s 19j 900 **HELP!* power down

Hi - could I inquire of some help in finding how to 'power down' a Hamilton 900 movement - cannot find 'click'...Have even removed the dial (no help on that side either, as I can see).
Had an 18s 940 to power down, and found the 'click' could be accessed thru the side, but no luck on the 900 - Is would pretty tight and only runs for a short time - hope that a clean will be all it needs! Would not want to start undoing the winding screws....Does it have something to do with the spring near the "19j" ?
Thanks in anticipation.

Just apply some winding pressure to the crown, you will see the click move this is the long finger type running under the wheel from "19 Jewels" to the other side, you then using a small piece of peg wood hold just clear while you allow the crown to slowly unwind, CAREFULLY!!!

Phil,

In the close-up from your image below this posting you will see the "bar-click" circled.

Once you understand the design you will realize it operates on essentially the same principle as the circular click does. Just apply force to the crown, you should then see and hear the "click" operating at the point of the red arrow shown below. Then you can follow the instruction Chris posted above to as he said VERY CAREFULLY and as you said slowly let it down like any other watch.

Bar-Clicks can take some getting used to...
