It's funny you posted this. I've owned a Gyroplan for a very long time, but just this week I took it out of a drawer to have a look at it.
It's missing the correct ratchet wheel but otherwise it is pretty nice. Note that on the picture the discs that indicate the time are not correctly aligned.
What is quite unusual on my pocket watch is that is uses a very high grade movement that I haven't seen on other Gyroplan pocket watches (a Lecoultre base I think). The movement looks kind of out of place to be honest. However, I do think that it is original to the watch.
Hello, these are my two Marvins. Please share your knowledge about the movements of those two watches. Especially for the watch movement of this military style Marvin. Thank you
