Amanico presents a detailed look at the Jaeger-LeCoultre Master Ultra Thin Perpetual Calendar 39mm, focusing on its evolution from 2013 to the 2017 white gold grey dial iteration. He invites the community to discuss the aesthetic changes, particularly the new dial color and updated rotor, and how these compare to previous versions and market competition.

In 2013, Jaeger Lecoultre unveiled a new Perpetual Calendar, housed in a superb case, the Master Ultra Thin.

It came in steel, rose gold, and white gold.

The White Gold, from 2013:

Then came the steel version, black dial, a very powerful offer, in my opinion. This version adds some coolness and power to an elegant watch.

This year, Jaeger Lecoultre offers a new iteration, in white gold and a grey dial which I find superb, and curiously more appealing than the one of the Master Ultra Thin Moon in the same metal.

Once again, I will repeat that the MUT cases are my favorite JLC cases. Top elegant, thin, not always ultra thin but who cares, I hope that JLC will, one day, use the larger MUT cases for their Master Control Line.

Another detail which is not a novelty, since the Manufacture changed the rotor last year with the steel case, black dial version...

The current rotor,

Compared to the one which came in the 2013 versions.

I find this latest opus superb with its grey dial. The chromatic combination with the case is very nice. Not too cold, but still discrete and elegant.

The only issue I see is the competition with the steel black dial, more affordable.

What do you think?

Best,

Nicolas

Key Points from the Discussion

Many contributors agree that the 2017 white gold model with a grey dial is the most appealing, despite its higher price point compared to the stainless steel version.
The black dial steel version is highlighted as offering significant value, providing a compelling perpetual calendar from JLC at a more accessible price than gold models from other brands.
The updated rotor, introduced with the steel black dial version, is widely praised for its improved elegance and design compared to the 2013 versions.
Some express a preference for the Master Ultra Thin cases, while others find them too slim with a diminutive crown, preferring the dimensions of the regular Master cases.
A point of contention for some is the year aperture's background color not matching the dial, which is seen as a misstep, especially given the watch's price.
The versatility of the grey dial is noted, as it pairs well with various strap colors like dark brown or blue, making it suitable for more casual wear.

Stunning case and I hope to see a nano Gyrotourbillon inside a MUT case in the very near future.

That grey dial is the best of them all, as well as on the MUT moon. Too bad it only comes with the white gold, which skyrockets the price compared to the stainless steel. I was at my AD a couple days ago and they had the grey MUT moon, but I have my eyes on the Master Calendar meteorite dial. Although, I too prefer the proportions of the MUT series over the MC series. Now if only they made the Master Calendar meteorite in the ultra thin case, I would be all over that!

Due to the price difference, I would opt for the steel and black dial version. Best wishes Alkiro

Black is a color of authority. My opinion. But the grey dial is my 2nd choice with its white gold case. Thanks for sharing Nico. Cheers Geross

dial (the contrast with the blue of the moonphase is stunning). If memory serves me well JLC. used a grey dial with moonphase also in the Master Control Moonphase, a very nice and more affordable option. Rotor wise I think that the first one whit which the it was released in 2013 does not make justice to a watch of this level, I really like the new one though. Best.
