I have almost forgotten

what an impressive watch this Zenith Pilot Montre d’Aéronef Type 20 is.  

With its legendary 5011K hand-wound movement.

This movement was considered the most accurate in the world in 1967 and received over 300 awards and prizes.
COSC-certified and tested by Neuchatel Observatory it only existed in the Zenith archives with 250 pieces and was specially switched into the Montre d’Aéronef Type 20 watch model.

In 2012 (year of publication) it won the international mechanical watch of the year 2012 award.

And with a diameter of 57mm it is - ALMOST !!  - wearable. Hahahahaha

Visited my bank safe today to switch some of my watches from autumn/winter to spring/summer and so had the chance to admire this leviathan again.

Yes, indeed it is.

And with 50mm this movement is also a giant where you can see every part of the movement like through a magnifying glass. Fascinating…

One of the best calibers.. but

The wearer needs a 20 inch wrist to carry this off with elan. A true collectors piece however.

What I like and why I can

ACCEPT this case size is, that here it makes sense. It’s not just a marketing gag. Often we see these big cases of fancy brands with ridiculous small movements inside. Here the movement is 50mm and needs this case size of 57,5 mm. Design follows function....

57mm is a watch for giants. Beautiful and worth collecting.

I was fascinated when I saw the first pictures of this impressing watch. I remember finding the only available piece in Vienna at Sunday in the shopping window of one of my ADs. My heart almost stopped. I wrote an email, I left a voice message: „Please do... 

Thanks for your special story

You catches your unique Zenith. I know how great it feels. At the doorstep getting a peace which you feel the watch brand made that watch specially for you only. At 57,5mm nobody understand the love for the watch either, so it’s your watch, and it feels l... 

To be honest…

It felt better than buying a 50K Patek. 😎

Truly a marvel!

Thanks a lot, dear nacelle!

A marvel … indeed… The movement as well as the case as well as the dial. Cheers Thomas

I remember wearing

 By: MTR : May 1st, 2021-00:37
this „monster“ during a trip to Paris with my family. And at night in the hotel room the sound of the movement drove my wife almost crazy. I had to banish the watch in the room safe. And even there you could hear the movement ticking clearly. Hahahahaha ... 

If they could give a small holder..

 By: chintu : May 1st, 2021-04:01
so that the strap can be removed; and watch can be placed in the holder and enjoyed on a desk. Or a watch fob-chain to hold the case and use as a pocket watch. The 5011 caliber is a joy to behold.

Excellent idea, chintu!

 By: MTR : May 1st, 2021-07:58
I think they also missed the opportunity to design other lugs. Perhaps movable or at least shorter ones like on the FF models (X Fathoms especially).

Thanks a lot, dear Fab.

 By: MTR : May 1st, 2021-00:32
During the last years I found a perfect way to wear this watch with grace. 😊 Cheers Thomas ...  

À la Gianni Agnelli👍👍😉

And perhaps like the former pilots back in the old days.

Beautiful movement

 By: imthehoo : May 1st, 2021-00:58
Maybe you could give us an ankle shot??? Would still be too big for chicken legs.


 By: MTR : May 1st, 2021-01:09
Excellent!!! I am afraid that wouldn’t change anything since I have also small ankles. 😂

Amazing watch!

 By: tudorctin : May 1st, 2021-07:21
I recall when this watch was released. It’s lovely despite its gargantuan size. I have a 47 mm watch and it’s one of the watches I will never sell. Size doesn’t matter if it brings a smile on your face.

Size doesn’t matter…

 By: MTR : May 1st, 2021-07:49
I have often read this phrase in another context. LOLLL I'm also a big admirer of the Blancpain X Fathoms, which with its 55.65 mm case is actually small in comparison. And also the lugs are constructed differently. Air and water. That would also make sen...  

Stunning piece my friend :)

 By: Makilla : May 2nd, 2021-19:27
This watch always brings a smile to my face despite some circumstances The design is just perfect all around 👌🏼 As you already mentioned the giant size is justified by the huge charming 5011k caliber. And the balance wheel sound oh boy ... it’s like a mel...  

Thanks a lot, dear Makilla!

 By: MTR : May 2nd, 2021-20:04
yes, indeed, what a watch. I love the sound too. You cann hear it two rooms away. Do you wear leviathan sometimes? The "father" is also stunning and perhaps ... a litlle bit ... ( ) more wearable. Cheers Thomas

Yeah I do wear it sometimes but rarely though

 By: Makilla : May 3rd, 2021-05:54
The watch is a monster and can easily hit stuff around As for the old one it’s such a sweet piece to own and especially if you’re lucky enough to find one in such a stunning condition Best, Laurent ...  

Oh yeah! I can call this luck ;)

 By: Makilla : May 3rd, 2021-05:56
The owner is an old man who’s had it for more than 35 years and the funny part is that he barely wore it pretending that the crown used to dig in his fist. So I didn’t miss the opportunity

Well to be honest I was more patient than lucky!

 By: Makilla : May 3rd, 2021-08:17
I’ve had my eye on the watch since 2011 😅 but never expected he would give it to me at some point and the only reason he did it is because his son isn’t interested in watches so I was basically first one on the list
