Never seen "Lemania" placed there on the dial
Never seen a real Lemania with a movement sigend by anyone else. Lemania start with movements, it's their job, so why have someone else's movement?
The photos re not terribly clear, to be honest.
This is an early steel movement, from what looks like a stopwatch, as there are no jewels to be seen. There is no anglage or other decorative finish on the parts, they just look stamped.
So I would guess that this has been creatively put together as a watch with new wire lugs from a pocket sized stopwatch.
I am not sure about the origin of the movement. Meylan used Lemania, certainly, but this is not something I recognise.
And hacking seconds without any other sub-dials would be a very rare way to do things....
If it's Lemania-powered, I'm interested. Tool Chrono - interested. Dive Chrono - interested. Interesting - interested
