Jaeger-LeCoultre

Hello Vintage Jaeger-LeCoultre Lovers, I am back with just a small observation… If someone mentions JLC case backs to you, what do you think of? I think many would think about open case backs… Me – one of the first things I think of is the planet-sphere! ...  

... I'm thinking of something like this: However, after reading your post I might be changing my mind. Excellent article! gatorcpa...  

The Gyrotourbillon and the Duometre. Best, Nicolas.

Yes, another beautiful and significant trade of JLC and their case backs! As I understand JLC have patented this pattern for movements decoration. Thank you, Gatorcpa – hope to one day join you in the MMR club! Best Blomman

The planet sphere is certainly one element of JLC DNA. It is very interesting to see the evolution of the planisphere design through the byears. The one from 1947 is without hesitationj my favourite. No wonder why I love the one on the new Master Memo cas... 

I was very surprised when I saw this one and made the connection! Was actually planning to write about another topic when I saw this… Indeed the Planet-Sphere is a part of the JLC DNA! I hope it won’t get lost… Thank you for your kind wo... 

was always tickled by this detail--an intriguing and now iconic marker--on the back of a watch case! thx for sharing J

And IMO, a very intimate detail as you normally don’t show to others. A detail just for your own pleasure! Thank you, J ! Best Blomman

What comes immediately to my mind is: The JLC Globe. Both an impressive World Time clock and a beautiful historical object, don't you think? Blomman, thank you again for your posts and your selection of ads, Regards,...

The actual Globe! On my hunting list for some time now… A question of clarification: the electric cord is it for the lamp only or also for the movement? Marv, as I know you are a connoisseur in old ads and documents it makes me very happy you like this on... 

If you look at the 2 male connectors at the base of the globe, you see that norms were not as secure as today! Otherwise, the clock movement is a 8-day mecanical movement. Regards,

I have read earlier that it has an 8-day movement. But when I saw the electrical connectors I got worried… Best Blomman

As a Jaeger fan I really apreciate when those of you enlighted share your hard earned knowledge with us mere mortals Master Compressor Memovox is one of my favourites (Now that it's been discontinued, I have an eye on one...but don't tell anyone), and tha... 

I hope you find your MCM! One of my favourite modern watches, actually she is my daily beater! A lady you can dress up or down depending on your mood… Thank you for your kind words! Best Blomman...  

Blomman, how pleasant : - your selection and focus on the backside of some iconic pieces and ads was again quite educative and somehow puts things into an interesting perspective. You are right, some of these beautiful backsides, are simply beautiful, and... 

In the world of JLC a lot of “hidden” pleasures! Almost like an archaeologist you have to look under every stone to get the whole picture! Thank you, HS – hope you have a great Sunday! Best Blomman

Am I day- dreaming? - Next and lefy to your lovely Geomatic, ( another Geo.... ??) Almost hesitant to use the word ? ... Did I miss something here ? Anyway, great post - and IF my snses are right, well - then unbelievably nice ! Pretty mesmerized I curiou...

I still vividly recall 'my' moment .. Of first sight ! Good that some caffeine was there .. THAT was real pleasure ) But with Blomman ? - nice Sunday surprise My best to you, hs

Especially like in your case, a parade of Grail watches in front of your eyes! Happens to me every time I am in Paris… I am thinking about asking the French government to ban me from French soil! At least that is what my heart doctor is recommending... 

Yes, in the photo is my Geo duo..! Best, my sharp eyed friend! Blomman

WOW,you had taken me by Surprise .. -- as had not been aware, that also the uncomparable, unbeatable Geophysic was with you.. -- Delighted for you, honestly .. with a (tiny) Little envy, as well.. Even more, thanks for that so 'en Passant' , nevertheless ...

I really love medalion on the back of my MMI even if it is not in gold. Best regards, George

Yes, I love the MMI medallion too! But imagine if it was in RG..? Best Blomman

But it would indeed look good. Best regards, George

... Blomman, you brought us another very interesting and stimulating observation: solid vs sapphire caseback which is a very tough decision for us. as like those signature solid symbols engraved on the caseback you showed us, each of them represents signi... 

On the Duometre, for example, having a solid case back would be a pain. On a more modest MUT, same observation. But on most of the automatic movements, I really don't see the interest to have a see through case back. And I don't regret seeing these nice s... 

... on those automatic movements, if the rotor is big to cover most of the movement, it is really no point to have sapphire back, except micro rotor may be still okay. stefan

I would not like a solid case back on a piece like the Duo for example. But I rather have the solid on some of the “simpler” watches. Honestly I have very few watches with crystal on the back, and I don’t miss it at all. But if I had a M... 

Very nice ads and very nice detail on the geophysic which later inspired jlc to create the master control. thanks again for sharing. best regards georges

There are so many small details that all together makes the typical JLC DNA. Best Blomman

To continue our education. Cheers

There is a lot to learn from these old documents. A very enjoyable way of study! Again, thank you! Best Blomman
