In 2016, Jaeger released two very nice looking watches, a new one, the Reverso Tribute Duo, and a new version of an existing model, the Master Ultra Thin Perpetual Calendar 39, in steel, with a black dial. Of course, you can also mention the Reverso Tribute to Gyrotourbillon, but it is playing in another league.

The Master Ultra Thin Perpetual Calendar 39 was first unveiled in 2013, in steel, white gold and rose gold, and has received, at that time, a warm welcome.

The recipe is simple: A refined case, and an elegant dial, which in black, adds a cool factor. While the other versions are understated, the steel black dial version is immediately catching the eyes.

Here it is:

Now, let's have a closer look at the dial... The moon phase is superb, the dial is well balanced, made with care, with its applied indices, legible, too, especially in this black version, and complete, as you have a danger zone indicator featured by a small window above the axis of the hands, and the window for the years, too.

Now, let's imagine you are in charge of the Design for this watch.

Would you do it with the window for the years, or without?

I photoshopped the image above, and let's see the outcome:

What do you think? Better with, or without the years?

Is it that important to have the years?

A side by side picture will probably help:

Ok, one thing is sure, Jaeger Lecoultre opted for a black background for the years, which is a very good decision, in order to not ruin such a beautiful dial.

But would you go farther?

Anyway, this version is gorgeous, in my opinion. It is not a new watch, but a very good iteration. And for those who are thinking about getting a perpetual calendar, certainly a good one!

Looking forward to reading your comments and thoughts,

Best.

Nicolas

Key Points from the Discussion

The steel version of the Master Ultra Thin Perpetual Calendar 39 offers exceptional value, with minimal competition in its segment, and features thoughtful details like the small slot in the hands for moon phase visibility.
Many contributors, including 'mahesh' and 'kev09', strongly prefer the dial without the year window, arguing it enhances symmetry and beauty, with 'mahesh' even suggesting a limited edition without it.
The 'danger zone' indicator, a small window above the hands' axis, is a practical feature that informs the wearer about periods when setting the calendar could damage the movement.
One collector noted that while the movement finishing is pleasant, it could be improved, but acknowledged that the current level contributes to the watch's attractive price point for a true manufacture perpetual calendar.
Some collectors, like 'Velociphile', expressed reservations about the watch's dial depth, hand shape, lack of French language options, and movement finishing compared to other JLC models.
The year window, while debated, is considered by some, like 'traineract', to be discreet and useful when needed, akin to a 4-digit display in IWC perpetual calendars.
Marcus Hanke suggests that integrating the leap year indicator into a movement bridge, visible from the case back, would be a superior design solution, though it would require a new movement design.

I’m not that keen on perpetual calendar watches...

...but this is a particularly attractive one. The black dial is lovely and balanced and really shows off the moon phase. All the functions are very legible but I much prefer it without the year indicator. I’m not that old yet that I can’t remember what year it is. Super looking watch. If I remember correctly there is a version of the MUT in black with moon phase but without the calendar. Also a very attractive watch. Regards Kev.

to be honest Nico...i think this is one of the best PC

& especially great value with the steel version - there is not big competition to this watch... i'm equally impressed by the level of detail, 'the small slot' in the hour & minute hands so the reserve is always visible...excellent thought. 200% no year window is my choice (we anyways 'hate' date-window) - adds to the symmetry & beauty of the dial ! if JLC gives a LE without year window - the queue starts from me BTW the ONLY reason you'll have a logic for having this 'year window' is there i

Without the year indicator there would be no way to set the correct date. [nt]
