Amanico's exploration of the Jaeger-LeCoultre Master Ultra Thin Skeleton Blue Enamel brings to light a rarely discussed, yet horologically significant, timepiece. His detailed photographs and initial impressions provide a crucial starting point for understanding this ultra-thin marvel, prompting a deeper dive into its design philosophy and technical achievements. This article synthesizes community insights, offering a comprehensive perspective on a watch that pushes the boundaries of slimness and aesthetic complexity.

This is a watch we didn't discuss a lot, since 2015, the year it was issued. 

This watch existed in white gold / blue enamel and in rose gold / chestnut enamel, both limited to 100 pieces, both with a 38 mm case, and most important... 3, 60 mm high. Now we can really call them Ultra Thin!

The white gold: 







The rose gold: 







I must say that the white gold blue is my favorite, but that the rose gold certainly is the most original, with its chestnut enamel. 

Two marvels and technical challenges, for sure, as this Master Ultra Thin is one of the thinnest, if not THE thinnest watch. in our modern times. 

One thing I would have loved to see: A more modern skeleton. I find this one a bit too baroque for my taste. 

What do you think? 

Best,

Nicolas

Thanks for sharing these pictures, wasn’t even aware of these watches existed! Regarding skeleton and baroque aspect thereof: I am fully with you - actually I like the skeleton on the back much more than the one on the front. It has is more of a form-follows-function and modern aspects to it. Herewith the only skeleton watch from JLC I ever had/saw: the Reverso Art Deco in WG, which I unfortunately let go.

What I find interesting here is how well the baroque skeletonisation combines with the mid-century modernism of the indices, case and lugs. It's like an 18th century oil on canvass set in a simple straight-lined frame. Both can be subject of appreciation and each complements the other. Who knows why such contrasts work in some cases and not in others? The recent Omega Chronoscope is a mess, with its 1930s dial and 1960s case. Yet it's the same process at work: combining styles from two periods i

I agree that they are too Baroque Mind you, Spain is Baroque, with the bullfights, Easter celebrations on the streets, etc. However, the attention to detail is exquisite, like time is something valuable and worth measuring in this way. Thanks for these. Have a good week.

Yes I believe this is the thinnest at 3.60mm, Piaget is a close second at 3.65mm. I've always wanted a 34mm MUT which also has the cal. 849. Thanks for sharing!

And I actually really like the copy! It may not be as well made but it is really cool to me and I like some features more than the original, lol
