Let me ad a little about the movement in this very beautiful watch.

Lemania was one of the main and major producers of chronograph movements. The Lemania caliber CH-27 (27mm) and CH27/12 (same movement but with a 12 hour register) - later registered as Lemania caliber 2310 and 2320 /12 hour register) was made really famous as Omega calibre 321 on the stopwatch used by NASA. omega, however, was not the only brand using this very fine, sturdy and /relatively( cost efficient chronograph movement, it was also found in Patek Philippe watches as caliber 2872 and CH27-70, among others.
Lemania (as the rest of the SSIH group) got into trouble because of the quartz revolution and SSIH, (Lemania, Tissot and Omega) became the foundation for the Swiss banks/Nicolas Hayek restructuring resulting in what we today know as the Swatch Group.
However, the old school watchmakers at Lemania were not happy about the situation and a management buy-out resulted in Nouvelle Lemania ("New Lemania") - that a few months later was sold to Breguet (as they needed a movement manufacturer). On a side note. Brequet later became part of SG, so the freedom of independence was not long lasting.
As the "fine chronograph movement" producer of SG kept the flagship movement 2310/2320 alive, and one of the best known secrets in the watch industry is that if you go back in time, you will today find it in watches from Daniel Roth, Tissot, Ebel, Ulysses Nardin and Roger Dubois. You will also find it in Patek Philippe as 5070/3970 and 5870, Omega re-issues of the moon watch, Breguet watches and Audemars Piguet as 2874. and VC as caliber 1141.
As with any other gauche, the level of finish as well as the addition of complications are many, from the rather basic versions to extremely finished movements, and as basis for perpetual calendar chronographs as well as tourbillions.
When it comes to column wheel chronographs this is probably one of the most tested through practical use, it is (relatively) serviceable and as the factory service bill would certainly be rather steep, as a "standard" movement, an independent watchmaker could for sure do service and repair work on it as well.
