Nitediver's 'JLC Masterclass' series offers a rare, detailed look into the intricate world of watchmaking. This installment, Part 2, focuses on the challenging assembly of the Jaeger-LeCoultre Caliber 875, providing a unique perspective on the precision and skill required to bring a complex movement to life. Readers gain insight into the delicate process of reassembling tiny components, highlighting the hands-on experience of a watch enthusiast.
(Part 2)
Now the real challenges comes: putting all the part back into the movement!
Ok, the two spring barrels are back where they belong. It is more tricky than it looks on the picture…there is a wheel under the right spring barrel. And there are tiny wheels on top of the left spring barrel, which have a square center and hence must be turned to fit on the axis.
Center wheel (for the second) and minute wheel (the third one, lowest in the picture) installed. More tricky than expected.
The first bridge installed. Needs a bit of practice, since the pinions need to fit into the borings….obviously!

Once in a while, we need some help by the master himself…
Looks almost like a real watchtmaker ;-)
Reserve de marche mechanism put in place
The large bridge installed. Almost done…yet the escapement wheel is still missing….
This was the most difficult part: the escapement wheel needs to go under the bridge which I found really hard. But it worked, all wheels were turning when I screwed the last bridge back in place. I was so excited, that I forgot to take a picture of the final result! Or maybe it was the excitement to see the Duometre a Spherotourbillon….

Do you know the treatment reserved to those for fail? :) Best, Nicolas
No champagne for those who fail....only white wine. Tough life, isnt it? cordialement, Stefan
... The impalement on the top of a church roof... ;) Best, Stefan. And congrats! Nicolas.
...that i managed to put all the parts back in the right place.... At any rate, traditons seem to be friendlier in Lucerne than in the Valee de Joux then. Have a great day, Stefan
as if we were there. but, don't do this at home! Cheers.
I had the pleasure of this class once in 2005 or 2006. I wish I could have a similar class again one day. Thank you for the report I enjoyed all three parts. Ruckdee
