Jaeger-LeCoultre

Four years since I bought the Jaeger LeCoultre Master Ultra Thin Perpetual Calendar - also known as Doctor Strange for its appearance in the marvel movie. To celebrate here are some pictures of today itself of this amazing watch: I have to admit that I al...  

and very useful complication

You have a couple of watches, how do you keep this Perpetual calendar on date? Watch winder? or it's really easy to set the date so you don't care to set again and again? Thank you

I got a watch winder from the JLC boutique so I just use that (in some cases you might get it as a gift!). In alternative going ahead is very easy just you can't easily go back if you go ahead too many days so I suggest a winder. I have too many watches b... 

very nice and reliable..

No, i have no Portugeser perpetual calendar. This watch remembers me about the IWC. Sure, the watches are not similar at many points. Is this some kind of family bands? Richemont, or any other reasons the looks are in the same design language? Not rare in... 

have certainly a larger and thicker DNA I don't think the movement are shared wither but then again there might be some similarities. A lot of perpetual calendar do look similar (e.g. Montblanc) perhaps the moon phase?

Do not take it to seriously. I tease a bit.

Dead giveaway is seeing the identical locations of moon, date, month and day of week; the clincher is 4 digit year indication in the same place. That’s not a coincidence. It could easily be licensed, adapted and thinned. Much easier than reinvented. Cazal...  

for me the bigger give away is the full year on the Botton left. I think that IWC used some JLC movements in the past. In this particular watch I think it is a perpetual calendar module over an automatic movement but I will leave it to the experts to say ... 

This is an IWC kurt klaus movement that JLC used. They updated it recently with their blue enamel series so expect it to go into regular production one day and replace your model , notably it moved the offputting off centre year window inside. ...  

and I don't like the broken year!

and I agree. This is a different implementation of the perpetual calendar. The positions are rotated around 180 degrees and the year shuffled over into the center in two bits. Cazalea

The IWC movement for the perpetual is based on an ETA and bigger watchbase.com the perpetual calendar module is a similar technology but is certainly not the same movement watchbase.com

whatever motivates the dates and moon is almost irrelevant, as long as it has enough oomph! In this case we don't know what's beneath but as Nico says, yes, it's a Kurt Klaus perpetual complication (I am not saying a separate module) that has been integra... 

that wrote " It’s an IWC movement "it is certainly not a movement but possibly the same module. I am not an expert but after buying the watch I learned that it was a module on the top of the JLC caliber. Not that it matters that much but there are some di... 

is a JLC base caliber with the IWC module www.watchprosite.com and other sources online confirm this. Thanks for pointing this out

which technically is but then I learned was a module on the top of the JLC movement. It probably makes sense..ultra thin in any case

JLC base movement, IWC perpetual calendar module

The silver dial version is very hard to find with the new all gold rotor

but also in 2016 when I got it was not so widely available in the boutique. Glad I got one!
