Raketa Winding Stems?

[Robbie010]

Can anyone tell me whether the winding stems for a Raketa cal 2609.HA & 2614.H are interchangeable?

They're from the same family so that should mean they share the same stem.

Perhaps further homework needs to be done:

Helpful info from Poljot. My only comment would be that the Cousins references can't necessarily be 100% relied on to draw the necessary conclusion. I recall commenting somewhere else where an ETA stem had a specific reference and N in stock ... but a look up with the direct Ronda number revealed a different amount in stock (and a different reference ... and a different price).

The composite below shows a 2609.HA stem (from https://www.youtube.com/watch?app=desktop&v=cbWoYjdzamY) and a 2614.H stem (from https://www.watchuseek.com/threads/assembly-of-a-2614-h.5235955/). They sure look the same but this is only inference; not direct experience with these movements and their stems:

Agree 100% that Cousins' references are not ... 100% accurate. That's why I said that further homework needs to be done - aka searching different catalogues, eBay listings, etc.

Hi according to Dr Ranfft  the stems both have the same number   W2988, so one would suppose that they are the same  and therefore interchangeable.
