My small collection (unfortunately no 89365 because of the missing weekday indicator)

Enjoy!
Robert

nothing small about that collection Roberto - great to see the ref 3705 in the collection.

I have a similar theme in this trio to your's :)

First time I have seen the Cousteau on the bracelet, looks VERY good.

Lovely collection.

Am I correct that the crown and pusher gaskets have also been changed out to stainless instead of blue black rubber?

Yes, and calendar discs and folding clasp :) Could not tolerate rubber on this real beauty.

Gives it a very different look.

I have mine on the original rubber and I like the rubber on the crown and the blue on the pushers, perhaps moving it onto the bracelet makes those look 'wrong'.

One question if you don't mind, the day date change, did you find a colour to match the face or did you go with black?

Cheers

Those chrono pushers and crown are pure preference issues, I enjoy them being steel even when the watch is on the black or blue rubber strap.

I had to go black calendar discs which does not really disturb me as the subdials have various colours anyway (slate-grey for the time seconds, blue for chrono subdials and was white, now black for the day-date).
What's more disturbing is the font style of the date disc, which greatly differs from the other fonts of the bezel and dial. The first CAD-scan used to show a special (though black-on-white) font date disc but the "red pencil" showed the way to the street version of the discs. I've purchased a whate-on-black date disc of the Porsche Design chrono ref. 6340 which also has its cons but is waiting to be built in. Only digits 3 and 4 differ considerably from the AT number fonts, but generally this is more in harmony with the rest of the digits. The red gold version has a matching font date disc... maybe the same will appear in a steel case too - I'd be more than happy with a day-date version of the 89356 movement...
Hope this helps!
Best,
Robert

Congrats! You have a fantastic collection out there, with some others in the background :)
Enjoy!
Robert

Pity that there are no Ardoise day and dates as that would be a good match. Good luck with the Porsche variant.

Good to see another Cousteau.

Graham

Very nice collection Roberto. Is there a special reason you want a weekday display on all your watches?

Kind regards,

Clemens

Nice, very nice.

I'll take the one in the middle all day, and twice on Sunday.

The one is usage:
- I do work according to a weekly schedule so almost every weekday at different places.
- Specially on summer and winter holidays (I have the luck to spend longer than average summer holidays) my brain "works" according to days of the week and not according to date.
The other is looks: date only on a Valjoux 7750 looks a bit lost while day-date gives the dial sort of (still poor) simmetry.
In an esthetical view my favourite dial layout ever is that of the Valjoux 72C /730. Some kind of similarity comes only on the BP FF Chrono Calendar with a FP caliber base and for a ton of money. I could well imagine the IWC cal. 89356 with a date at 3 and a weekday at 9, or date at 6 and weekday at 6 by a small hand, same axis with seconds.
Same goes with the Fliegers, a 0-60 turning bezel is a must. (Only my two IWC Fliegers don't have it, but no watch will come home with me without this in the future. Functions that I use them all: continuous seconds, 12h Chronograph, day-date, count-up turning bezel. From the Cousteau I miss the micro-adjust clasp, the manufacture caliber basis and the croco leather option. Still the watch that comes nearest to the watch of my wishes ever.
Coming back to your question: Many use day-date feature, as (after the footprints of Seiko in the 1970's) this combo was/is very widespread and a feature changing daily makes much more use than - say - a month display on the new QP module by IWC. Just my two cents of course, but a nice complication does not necessarily mean its usefulness.
Clemens, I give significance to small things sometimes, so I'm more than happy with the huge step forward of the new, double-pusher bracelet clasp of the AT bracelet. The micro-adjust of the same design clasp of the Fliegers would make the bracelet a best-ever in the watch industry. Strange is (among others) the AT rubber strap coming on a pin buckle only while the rubber of the YM comes on a folding clasp, and the non-existance of a croco leather option for the AT-s. Anyway, I wear the AT Cousteau almost 7/24 and 95% on the bracelet. And love this combo.
Regards,
Robert

Thank you Robert, it's clear you know exactly what you want and for good reasons too.

Kind regards,

Clemens

What is the clasp from? Seems to have a cut out which mine does not have.

Congratulations, Robert. You have a beautiful collection of IWCs! I love them all, especially your Cousteau on bracelet. Job well done, it looks fantastic!

Cheers!

Clasp is that of the MkII. AT bracelet (from actual production). I think it's the investment of the century, so much better than the previous one. I'm waiting for the qick-micro-adjust clasp of the newest Flieger bracelet to be adapted for the AT-s too!

I appreciate your comment! Thx!
