The green enameled Master Grande Tradition 8 Days Perpetual Skeleton is probably the last version to see the light. 

It has been a long way between the First Master 8 Days Perpetual and this one. 

All started in 2004, with the Antoine Lecoultre, a plain dial hiding a 8 days manual winding movement,  with a modular construction for the perpetual calendar. 







Then, in 2007, Jaeger unveiled a skeleton version, in platinum, first, then, the year after, in rose gold for the JubilĂ© year ( 100 pieces in platinum, 175 pieces in rose gold ). 





In 2011, we had a new Master Days Perpetual, in steel or in rose gold, plain dial. 40 mm case. 





In 2014, a surprise... Jaeger Lecoultre gives birth to another 8 Days Perpetual Skeleton, with a delicious champlevĂ© blue enamel " ring " surrounding the dial. 





The skeleton movement is finely engraved, which was not the case on the 2007 version. 

Engraved on both sides, as you can see here. 


The case is 42 mm big, in white gold, this time, and 11, 55 mm high. Strangely, the whole watch looks much slimmer, more balanced than the Master 8 Days Perpetual Skeleton from 2007, which is 41, 5 mm big and 11, 8 mm high. 

The explanation? The Master Grande Tradition has a more elegant case and refined lugs. The chunky look of the Master Case is over, now. That is the major flaw of the Master 8 Days Perpetual. Especially the Skeleton version from 2007. 


The best evidence of what I just wrote is that it is because of that ( case ) that I traded my Master 8 Days Perpetual Skeleton. If it had the case of the Master Grande Tradition, I would have kept it.

Some words on the movement and the dial, which are naturally interlocked since you see the movement, front and backside.

The movement is the same for all the 8 Days Perpetual Calendar versions, the Cal 876, but here, as it is a skeleton, the complete reference is 876 SQ. It beats at the pace of 28, 800 alternances and is made of 262 parts. 

The movement is not only skeletonised, it is also chiseled  by a Master engraver who uses a burin for that purpose. 


Did you know that it takes two months to skeletonise and decorate this movement?

You will also notice the shape of the bridges, which represents a planisphere, a symbol dear to Jaeger Lecoultre since the famous Geophysic, born in 1958. 

Skeleton, engraving and... Enameling. This is the third stage and not the simplest one. 

First, you have to decorate the white gold rings which are chiseled, surrounding the movement front side and backside. Then you delicately cover the rings with enamel, and put them in the kiln, several times. 

The final operation consists in polishing the surface of the enameled rings with diamond powder.

The enameling process requires 2 days to be successfully achieved. 

All this is made under the expertise of the Complications Horlogères Workshop. 

On the movement, you have the sub dials dedicated to the day, the date, the month, the power reserve and the moon phase. And a window which shows the year, stuck to the month disc. 





So to say, this is a full perpetual calendar. More legible than the 2007 version which had transparent discs. 

A last detail, the leaf shaped hands. Which I like a lot. 

In 2016, the green version of the Master Grande Tradition 8 Days Perpetual Skeleton Enamel has been introduced in the catalog. 

Like the blue version born 2 years before, this is a limited edition of 200 pieces. Like its younger brother, it is a white gold watch. 

The sub dials have been darkened, the moon is in gold, and there is one question about the color of the hands. On the press file pictures, I've seen darkened hands, while the watch I photographed had heated blue hands. 

A last point about the number of pieces, for the blue or the green version. 200 pieces, I always found it was too much for this kind of watch at this level. Even more if you consider that 100 skeletonised movements were made for the 2007 version in platinum, and 175 more for the rose gold, in 2008. Even if they are not treated / decorated the same way, it threatens a bit the notion of exclusivity which should be strictly linked to this kind of watches. 


I never had the opportunity to see this version, in green, before past week. It was time to make a review on it, and, as an extra bonus, to post a link to a video about this watch: 



Looking forward reading your comments and thoughts,

Best. 

Nicolas

The most impressive element in this timepiece is the work made on the back. It makes me think to a “lace globe”. If this movement and this special back could be used for a world time timepiece that would make sense and that would be a true marvel for me

My first impression made me prefer the steel one.

After a few more looks back and forth, I began to appreciate the seemingly complicated dials of others.
