Today will try to find a free spot on the wall for it. It’s HUUUGE. 

Awesome impressions and watches Tonny!

Thanks for sharing!

Can’t wait to be there too on Friday! 

I checked the books and correct my statement former statement a bit.

The Ref 5002 movement was changed to 3 Hz frequency. These are the Transitional models.

Reference       Caliber     Freqency    Year     Info

5002                 50110       2.5 Hz         2002     1. version

5002                 51110       3.0 Hz         2005     Transitional

5004                 51110       3.0 Hz         2006      

5004                 51111       3.0 Hz         2008      

In 2006 the whole layout of the watch and dial changed to Ref. 5004. The movement frequency stayed at 3 Hz.

The original 5002 had a frequency of 18'000 half beats per hour which is 2.5 Hz. That was the frequency of a pocket watch movement. The caliber 5000 was developed with that specification. It was a movement with 7 (8) days of power reserve.

It turned out a bit tough to regulate properly so there were some technical adjustments to the movement concerning the balance spring. The frequency was changed to 21'600 (3 Hz). The rest of the watch stayed unmodified. I think that was the transitional version. 

Later the movement was changed to 4 Hz and the ref # changed as well. The case to my knowledge stayed the same.

Please correct me or add some missing details if I'm wrong or left out some important information.

Just for the fun: 

What are you wearing?

Because I'm privileged with 2 wrists and a few watches, I love to wear double. Just for symmetry reasons ;-)

Someone else does 2?

Or a different (watch) fetish? ;-)

Huge congrats and great to see that awesome watch has come to loving hands again. I knew Mr. H. G. personally and know that the watch was loved for many years by him as well. He was a very active member of this Forum too and even painted a picture of the watch which might be still in the archives here (somewhere hidden).

I don't know why he turned away from IWC one day. Don't have any contact for many years now. But I hope he's still doing fine.

A picture of the beautiful watch would be great. At least the dial side. ;-)

I'm not invested in Mark XX, but great to see those watches behind steering wheels piloting great cars.

There must be some more of these great pilots watches around here.

My very first IWC watch was a Mark XV which is long gone unfortunately. :-(

Great theme, Nelson!

Here's my contribution: 

The ATBON, a very small series of a very special watch among diving apprentices and IWC friends. Some of them never made it to the diving lessons but are proud owners of this outstanding piece anyway ... ;-)

Hi Panos,

such a beautiful badass watch! A dream!

Huge congratulations and welcome to the Forum here.

Glad, Andreas could help you so quickly.

This watch was one of my dream watches for a long time and I'm so happy about it.

As always this is a highlight in the watch year and what a fantastic opportunity!!!

I’d be so happy to join and meet you great guys there!
