According to the "Date your IWC" database, movement No 285624 is a Lépine c. 52 - 19lig H7. 

As Cromagnonman said, you will have to measure the height of the movement in order to verify. 

The 2010 Big Pilot edition "Boutique Las Vegas" IW500429.

Thank you to IWC for such a tremendous opportunity! These collector meetings are such a special time, and the chance to attend Watches and Wonders and visit the booth as an invited guest is just fantastic. I am all for both a welcome and a goodbye dinner, and maybe one in between;) 

A beautiful flieger, Tonny, huge congratulations!

If it is just 2 sub-dials arranged horizontally that you are after, reference 5017 fits the bill. An iconic piece.

Borayama, this watch on bracelet is definitely a fake.

Chube, the 3716 you show appears to be legitimate, I do not notice anything unusual.

Congratulations, Tonny, a beautiful watch and a true IWC icon! Looking forward to your next Portuguese reveal;)

Wow, Elton that certainly is an amazing collection. It seems you do favor the pilots, so I would suggest the Pilot’s Watch Performance Chronograph 41 Mercedes-AMG PETRONAS Formula One™ Team. There you can add a new model and a new material. I have seen a few Ceratanium bracelets out there paired with the Pilot’s Watch Chronograph 41 TOP GUN Ceratanium®. That would be nice to see on this Petronas model...

Some collectors would prefer to have the box and papers, but it shouldn't be a deal breaker on a piece like this. The boxes don't hold up well over time, and the warranty card has long since expired. It is nice to have those things to prove authenticity and ownership on a newer watch, but this is not a watch we typically see counterfeited and is not high-value. Great watch, though. 

If you are talking about the Mark XV (I assume the 3532 was a typo), then I would opt for the 02 with bracelet as it a beautiful bracelet, and not readily available.  

As for the lume, I, personally like the patina the tritium develops over time.  But it can also cause service issues,  as the tritium material can degrade and disintegrate, with the danger of debris entering the movement. IWC service likes to replace tritium dials and hands that show any signs of degradation, so paying for the replacement may be inevitable at some point.  

While waiting for my Portuguese Perpetual Calendar 502218 to kick over from 2024 to 2025, I was looking through my earliest IWC catalog, from 2007. I sure do miss the print catalogs that IWC used to produce. Great stuff to look back through, years later.

I was quickly met with an image that had left a long lasting impression. An image of a watch that appeared again in subsequent catalogs, but never in such size and detail as it appears in this (and possibly prior) edition(s). It is the absolutely stunning American-cased Jones Caliber that currently reside in the IWC museum, but is part of the collection of Hannes Pantli:

Just gorgeous. The image has stuck with me since, and when I have searched for it again, I seemed to always come up with much smaller, lesser detailed images from other sources. Well, to my delight, I rediscovered this photograph, and was able to see even the details of the steamer's name on the side of the paddle wheel, the Eagle. 

Which led to another search and the discovery of a new image, the source of the artist's inspiration for the case engraving: 

Very cool to see the image source of a gorgeous Jones. It used to be I was most interested in pocket watch movements. But these old cases, along with the movements, are real treasures, and my appreciation is only growing. 

Attention IWC Team / Andi

I posted this originally from my Android phone, runing Android 14. When looking at it on my MacBook Pro running Sequoia 15.2, the first two images I posted are smushed down vertically. These images are actual photos that I took with my Android phone. The third image looks correct, and is an image that I had downloaded to my Android phone from the internet, rather than photograph.  

When, on my MacBook Pro, I right-click on any of the images and chose "open image in new tab," all of the images open correctly in a new tab.
