Stems for watches are usually referred to with a 'Ronda Number' (and not just for Ronda watches like yours!).

I believe the Ronda Numbers for your movement are 1848 for the standard wind/setting stem and 1790 for the alarm wind/setting stem.

A quick look on ebay gets me this: https://www.ebay.co.uk/itm/RL-RAX-RONDA-Watch-Winding-Stem-x1-Part-401-Many-Calibres-CHOOSE-FROM-LIST/153716373246. If you look through the items available you should see a picture of the 1790 stem. Probably then a good idea is to check your standard stem ... if it is indeed different from this stem then the 1790 is more strongly confirmed as the one you want! You can then get from this ebay source or another source @watchweasol has suggested.

2 stems at top are mainspring winders. The bottom 1 is the alarm winder.

I found this pn W3406  on http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&Ronda_1223_21

Yes so it is the 1790 you need. If I take the pic from the ebay seller mentioned and put your broken stem next to it this would seem to confirm this:

That reference you've found on ranfft is the Flume number i.e. because Dr. Ranfft is German he uses this company for parts: https://www.flume.de/en/index.html; so it is their part number reference. As mentioned however it is more usual to see the more widely recognised Ronda reference and a company like Cousins lets you buy stems from this number: https://www.cousinsuk.com/category/filter/ronda-stems-by-ronda-number

Thanks WatchMaker. Much appreciated.
