Thanks for your kind words zeo9, I've replied to your PM.
The Reverso is the iconic JLC for me.
That particular model was the only Reverso I'm aware of which had a jump day function on an otherwise plain reverse.
Others are have their complications on the reverse or a clear crystal, which does away with the original intended function, being to protect the watch.
The offset seconds dial seems to only have been with the 8 day movement, the other iteration having the reserve indicator on the upper left side and the date on the lower left side, which makes for a very busy dial.
cheers
