·Quite a show. I’ll guess we’ll see if it ships off to the buyer (for $12.50) or “never leaves the safe”

·How does that movement work? Second escape section on top or spring loaded like Rolex True Beat ? Kind regards. Achim

·The hand moves like a quartz watch😀

that was quite obvious. and does not answer my question. Is the mechanism, that produces the jumping second hand spring loaded like the Rolex or is there a 2. escape section ? can you answer that ? or somebody else? kind regards. achim

There is a springloaded double wheel (it is the 3rd if I recall correctly) and there is an extra "whip" which blocks the seconds wheel to jump forward every 1/5th of the second by releasing only after 4 of these wheel movements - hence the 5th oscillation is allowed to go thru which means it jumps only once a second.
Well, I am not a watchmaker and as English is not my first language I am not sure if I explained it correctly. I am confident Al Archer will chime in soon and explain it better than I am able to do it.

Is it in principle the same technique as employed for the dead seconds chronometer clocks?

See foto below - I have marked the spring loaded wheel and the blocking whip

·Yes, from the principle I guess but it looks completely different concerning the escape. The cal. 120 (of the clocks) has some sort of second escapement set upon the common escapement and is large, has the shape of an anchor while in cal. 372 it is a small whip which blocks.

Interesting to read that it is a slightly different solution to the same 'problem'. I wonder if both of these movements in development at the same time and what the motivation was to go in this direction?
