The first step of this watch, born in 2009. Around 1600 pieces were announced to make the Cal 182. You will notice the jumping hour... Which disappears in the definitive version, in 2013. The definitive version adds a G Key at 9 o' clock.` With the defini...  

I'm unfamiliar with this one

It seems highly complicated, did you say 1600 pieces? Never seen double stack pushers like that. Thanks for the pictures. - Kevin

1300 pieces, now. As for the pushers...

The higher pusher at 4 is used to change the striking mode ( Grande Sonnerie / Petite Sonnerie, and Silence ), while the higher pusher at 2 is destined to set the hour ( only forward ). The 2 other pushers at 2 and 4 allow to set the minutes forward and b...

The movement leaves me speechless! Do you know if the jumping hour was instantaneous or is it the same mechanic inside as for the Nonantième? I'd love to know how long it takes for an experienced watchmaker to assemble it! Best, E.

I think it is a fantastic achievement

any Grande Sonnerie is, in my view. I see what you mean by clinical but I would certainly not refuse one gifted to me! Best Andreas

So with JLC a watch with such complication

This is an absolute marvel piece from JLC

I wonder if they can top this piece with another marvel creation. I hear they are working on something else 😊

Yes, but something in a round case 😉

You know I don’t like rectangular cases.

Noted. ;)
