From an etymological standpoint, chrono-graph means ?writing the time?. The chronograph invented by Rieussec in 1821 (patented in 1822) literally placed a drop of ink to mark the end of the measurement (while the hand continued turning). Strictly speaking...  

seems to be coming. Jaw you are perfect to make us desire. Thank you for your new input to our JLC knowledge. A great story full of wonders. We are getting closer to the jewel.

I'm interested in the date of the first production of JLC's chronograph movements by machine and whether they really pre-date the Waltham patents on the subject(1880, with production soon after). This was the pinnacle of American movement production as ca...  

Everytime I watch a series that says "To be continued", I get very jittery. As always, its like nearing the murder scene. The suspense of waiting till next week!! BUT...as I love chrono, I'm willing to wait as I know JLC will not let me down Thanks again ...

Greetings, Was the chronograph movement not released because they let Lange use the innovation, the same way they let lange use the big date mechanism first? thanks for the write-up! I can't wait to see the watchmaker's watchmaker chronograph. Francis

the Jumping Minute feature is not something new in chronographs. For example, the rather old and common Valjoux 72 and Lemania 321 feature this function. Therefore it can't be something that JLC saved for Lange use only, as you can find it on many other c... 

Hi Guys, Lange's minute counter is instantaneous. Precisely at the 60 second mark, the minute hand jumps instantly to the next minute. Most minute counters are semi-instantaneous. A few seconds before the minute changeover they start to creep a little and... 

The calibre 829 project was costly, but possibly due to the ready availability of lesser chronographs at cheaper prices, the response from the market wasn't exactly hot then. Gunter Blumlein was one of the most (if not the emost) admired industry leaders.... 

For most technical watch brands, a minimum of a clear 5 year product strategy is essential. The ability to continuously produce innovations that meet high expectations is a real challenge for most. Jaeger-LeCoultre, in contrast, has many working prototype...  

Thank you Jaw for all this precise report (I am eagerly waiting for part 3). This new caliber seems amazing. AMAZING!! You say it incorporates ALL autotractor improvements, so I guess it is an automatic caliber? I hope to know soon what is the use of the ...

...that this is going to be quite a MASSIVE case. Not to jump the gun, Jaw, but any idea of the case size? - Daniel

Thanks Jaw for another fantastic report, nicely split for drama and suspense ! A lovely addition to the Compressor range.

I have been lookng for "One Watch" to wear for 95% of what I do. I need a chrono, and it needs to be sporting enough for hiking, biking and playing with my two boys. But it also needs to be something special enough for me to hand down to one of those two ... 

Do you know if JLC is planning a chronograph in the Master series? Best wishes antonio

is that 6oclock window for?

World Timer (no dual time), no split and a seconds disc indicator at 6 o'clock Jaw

?

Overall a well balanced dial, the most symmetrical compressor dial yet. The 30 minute subdial gets an unusual treatment - at first glance it looks like the normal date dial. IMHO, the hands on the 30 minute subdial are too different from the hour subdial.... 

Jaw !! My Jaw(s) are wide open !! Sorry What a beautiful report ! What a beautiful watch - Now how do i justify this to my wife.... Hmm... Waiting for more Jaw, Keep up the stellar work ! P

Fantastic and thank you Jaw for the scope! Regards Jim

looks like it acts to provide a suspension system for the movement when it's subjected to impact or shock. A cool piece of engineering art. Thanks for sharing,Jaw. >>>>>Zach T

The case design, layout of the dial, the anti-shock system with the case, the movement, and etc... All these are so well executed and I really like it... BTW, Can someone tell me what is the function of the disc with red and white colours? Chai

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 ... 

Not only the 1965 memovox wasn't the first waterproof alarm watch, it wasn't even the first JLC waterproof alarm watch!, the facts was misquoted because of some mis-communications. The first JLC waterproof alarm watch was actually the Deep Sea, a modele c...  

I didn't know that the DeepSea was from 1961 also. I have seen it bearing bothe the US LeCoultre and the swiss Jaeger leCoultre names on dial (see this example of swiss dialed one)

I like the engineering spirit exuding from them. The size is prohibitive indeed and I believe the price will be the same. Can't wait to see what JLC will offer for the non-Compressor series, chronograph or not. Ruckdee

the mid to high end chronograph market will never be the same again, what do you think if I say it will PROBABLY priced below the Girard-Perregaux ww.tc? But don't take

By the way, could we know the siez of the "simple" compressor chrono? Thank you

I do not see the "inlay" around the pushers/crown, which is present on the Extreme worldtimer version, so I assume this varaint has a more conventional case layout? Regards, Marcus

Jaw, Thanks for the fascinating series. I have 2 points of order. 1st: Force = Mass x Acceleration; so for a given external force (impetus), the acceleration of the watch would be less (i.e. less rate of change of velocity or displacement) if the Mass was... 

Impact is exerted when the watch is stopped from acceleration, the acceleration just before the impact is the a, the force exerted on impact correlates to mass. It takes much more force to stop your "Densitometrium" than Titanium during impact with the sa...

Thanks Jaw for the preview of the new watch and movement! I can?t wait to see the watch and try out the chronograph function. Vernon

The press release says the Extreme has a Power Reserve indication. Is this the red disc above 6, or is the red disc for running seconds? If the latter, where is the PR indication? Daniel

The use of Titanium and Stainless Steel (or Platinum) is functional, when you use 2 metals with different densities and properties, shock can be deflected, and hence reducing the potential shock to the movement. The winding stem has a collar resting again...

I'm 100% impressed and awestruck by these new JLC releases. I was never a big fan of the Compressor range, but these watches have changed all that. To those who complain about the size: get a life. Just because you think 46mm is too big for you, does that...
