Such a beautiful movement and only a watchmaker gets to see it.

It is a shame but yes it is beautiful

Thank you

What a beautiful video of a wonderfully decorated and running Jaeger-LeCoultre movement: Thank you so much for sharing this 👍👌👏❤! If I were to own this watch, a sapphire glass bottom would be most welcome as this incredible craftsmanship should not be hidden.

[@FrenchWatchCollector]

Thank you so much. Would love to see the calibre too but it will change the history from this watch

Thank you. The watch only has two hands and not three with a second hand

[@pafeso1659]

La finition n'est vraiment pas comparable aux autres. C'est sérieusement impeccable! Maintenant il ne reste qu'à la comparer à une VC moderne 😅🤣

[@FrenchWatchCollector]

La finition est top. Je n’ai pas de moderne malheureusement 🤣

[@Nachovalenti899]

Great service and I enjoyed your video. By the way, what kind of crystal has this watch? Hesalite, mineral or sapphire crystal? Many thanks.

[@FrenchWatchCollector]

It is mineral

[@stevemoreno6241]

Was this calibre made by VC or was it made by JLC and VC did some final finishing?

[@douro20]

It was once the case that JLC provided an ebauche but VC actually makes this movement entirely in house- more than 90 percent of its parts are made in house.

[@stevemoreno6241]

​@douro20 I appreciate the in-depth explanation later in the video.

[@FrenchWatchCollector]

The design was done by JLC and the production was on house. This calibre was a very common calibre at Vacheron so it was done in house

[@matthewwalker2100]

Ladies, gentlemen: Quiz time! Our host wears one watch during dismantle: another two during assembly. What are they? Best guesses accepted! Monsieur FWC is asked to let us know the answers next week. I haven’t a clue. I think the first resembles a brick. So thick, while working on something so thin!

[@FrenchWatchCollector]

For sure it is thicker than the vacheron 🤣

[@matthewwalker2100]

@@FrenchWatchCollector Um; my best guess about the first watch . . . it's a "Tool Watch" and . .um. . . .a Tudor Black Bay because that's 15mm (more than half an inch) thick! I suppose you could use it as a hammer. Just the right weight; 175 grams!

[@matthewwalker2100]

@@FrenchWatchCollector The second watch is (according to Google artificial intelligence); . . . . . . . . Well; yes; I mean no; I know nothing about watches (except using one) . . . but it's fun to learn! Um, maybe a blue Grand Seiko AUTOMATIC without the date. Perhaps, maybe.

[@5850terry]

Was this movement made for VC by LeCoultre?

[@FrenchWatchCollector]

It was designed by LeCoultre but made by VC

[@gang208]

I am a little surprised to see a couple of wire springs (5:54) in this watch. I am under the impression that to have a "Poinçon de Genève", a watch cannot have wire springs.

[@FrenchWatchCollector]

It is what is thought too but there is a Poinçon de Genève so it might have changed

[@BradyBegeman]

Is it possible they are replacements? Seems extremely unlikely, but who knows.

[@da___man]

Funny, I am just finishing up on a cheap Gruen from the 70s that uses a FE 140-2a (france ebauche). It has a similar calendar mechanism. It simply involves a day and date jumper under the calendar guard/plate. The two springs, one for each jumper, are just passed through a cutout in the plate. Mine had no instructions, unlike the VC. You don't want to know how long it took to figure it out. However, the end result is a very simple but thin calendar mechanism. In my case it was done to save money. I assume, in the VC, the wire springs are there to make the movement as thin as possible. Overall, a very elegant way to achieve the needed results.

[@sailgears]

What type of red oil did you use?

[@ralphferrara5152]

There looks like a lot of dirt or lint in the spring barrel.

[@FrenchWatchCollector]

The barrel is pre greased from the factory when new. From up close it looks like it is dirty but it is the grease around

[@ralphferrara5152]

@@FrenchWatchCollector thanks for the reply. I love your videos. Keep them coming.👍😁

[@da___man]

Are you sure it is only a 4 year old watch? It has watchmakers marks in it which has been done for a long time. Also, a watch from a quality manufacturer such as Vacheron should be running better after just 4 years. The 2020C mark inside the case back is likely a reference number and not the year of manufacture.

[@FrenchWatchCollector]

The 2020Q is the reference of the watch and not the year. This watch is much older than 2020

[@SalamonBauzek]

It's sad that watches that look good cost over 1k+. MAMACOO watches are REALLY well made, and it just shows how a brand name on a watch can make its price 10x higher. I understand that if you look under a microscope, you'll find the difference, but just how many of you really inspect a watch at that level when you see someone with a watch?

[@RabbitWatchShop]

A lot of vintage models such as this the Swiss legacy brands manufactured are so ugly and boring. This definitely doesn’t come from the “Holy Trinity” era.

[@FrenchWatchCollector]
