First of all, the Master Compressor Chronograph Ceramic (GMT) is still on the catalog (just checked):
This one, was released during the SIHH 2017.
I was never a big fan of this huge crown and there are better ways to assure water resistance.
Now the Extreme Lab is not sexy?

Or, changing for a dress watch, the JLC Master Ultra Thin Blue Dialed is not sexy?

I, as many JLC aficionados, was expecting more for the SIHH 2018 but I understand that the Swiss watch industry had a very bad 2016 and, even recovering in 2017, this will not give to JLC time to release more watches.
On a summary, I don't want JLC to go back to previous models but to bring true innovations to the market, like they did with the Duometre and with the Extreme Lab 2.
With the Duometre "platform", they can produce wonders and I hope to see a SS Duometre with a smaller price or, allow me to dare, to have a Duometre Rattrapante.
Cheers,
