I've just finished refurbishing a Memostar Alarm with AS 1931 movement (same as 1945 but with date and running at 21600). I was also surprised how many parts are available at Cousins. Like you, I was missing the alarm stem (Cousins stock them) and I needed new crowns. It's a nice simple movement for an alarm, easier to service than a Seiko Bell-Matic. BTW I made a note in my Servicing spreadsheet: "Pull out winding stem before removal". It may have just been wear on my movement, but I found that the yoke could move out of the clutch if the stem was removed in the normal position (like some ETAs). You might find this interesting -

I picked up this alarm watch at a flea market several months ago and recently decided to investigate. I am not finished, but well on my way. As you can see, there was significant water damage. Running these parts through my L&R cleaner was not enough to clean them, so I did manual cleaning with one-dip and cotton swab (the dense pointed kind). The wig-wag was stubborn--the two gears would not release from the plate. I soaked it in Kroil overnight and that did the trick. There was some rust on the balance staff, but not actually on the pivots themselves. Nevertheless, I chucked it a step-chuck on my lathe and burnished the pivots. The watch is running and I have confirmed that the alarm drive train is functioning. Since I am missing a stem for the alarm, I have not done the final assemble of the alarm components. Surprisingly, there are lots of parts available for this movement on Cousins. I will probably get a couple of stems and maybe some other parts that I deem necessary. The watch is running at weak amplitude (about 190) and shows some poising issues. I will work on that. The last two pictures are after partial reassembly. -

Exactly! It may not really be a joke, but the actual truth. -

The movement is placed on the base and the centre screw is raised until it contacts and supports the centre pinion, thus stopping the centre pinion from sinking in when the second hand is pressed on.
