I will be my boring self again and do a minor correction to your JLC history introduction.
The memovox was actually not "the the first waterproof alarm watch" when it came in 1965.
This title is held by the Vulcain Cricket Nautical, launched in 1961, and developed and actually used in extreme underwater conditions by some ot the diving pioneers (incl Hannes KELLER )
(you will inevitably note a striking visual similarity with the later Memovox diving watch. This is due to the fact that both cases have been designed, engineered and built by Piquerez, the inventor of the compressor case. Actually, many diving watches from the period were quite similar in appearance, and the only 2 watches with alarm, the Cricket and little sister polaris are therefore quite close).
Now, back to the chronograph...
I am very impressed by all the technical content.
While the sport styling doesn't do it very much for me (I have never been a big fan of the compressor line), I find the size, at 46+, quite scary!
Now, I really wish that without the complex shock-absorber case, the movement can be integrated in a more "reasonably"-sized case, Ideally with one of the pure Janek's classic designs.
I think it could be a must and would have a good role to hold in the dress-chronograph segment.
Kudos to JLC for this beautifully engineered movement !
