Indeed, quite a special situation: producing a top notch movement without using it for the own watch line.

- the Audemars Piguet 5402 to become the AP cal. 2121 - the Vacheron Constantin 222 to become the VC cal. 1121 - the Patek Philippe Nautilus 3700 to become the PP cal. 28-255 Cheers, HSTE ...

A great and thin automatic movement. One of the thinnest, if my memory serves me well. [nt]

Too bad JLC has not its “Genta style watch” (not the case of the VC however) with its own caliber inside

Genta Style. Not Genta watch. Ref 24000-42, Cal 906, Chronometer. ...

Well played. This one is probably the best example of what a JLC “Genta style” could have been

Perfect period and, in addition, a very rare timepiece. Maybe a little bit more “macho look” would have been interesting but that’s not the main point here. Best wishes Alkiro

I will try to find other examples. [nt]

I trust you to find other candidates

Albatross. Never very popular.... [nt]

True. [nt]

Humm, I’m less convinced by this one

Great picture and summary...3 fascinating timeless watches. [nt]

Thank you for watching

How much real change is there or is it more cosmetic. [nt]

A picture of the movement

Here you are.

Thanks my friend!

My pleasure. [nt]

Thanks Nicolas for providing this. I actually never opened one of those three for - I guess - obvious reasons.

I understand. ;) [nt]

Amazing trilogy!

Thanks Todd. I tend to be in the same camp, i.e. AP

Very cool!

Fascinating! Thanks HSTE! 👍🏻😃 [nt]

Thanks for your feedback MCG!

Great Pictures HSTE

Thank you Christian, glad you like them.

Fascinating shots indeed

Gladly done, it's fun to do.

Such beautiful cases [nt]

Very elegant indeed.

So it should be a third of the price by now.

???? I do not get this type of Dutch maths.

Well, that same movement has been sold so many times that the law of large quantities should apply.

Ah, got it. If there is one (standard) movement that has not been used/sold in large quantities then it is perhaps this one. If we would talk ....

What was the price for a standard ETA? Couple of euro’s? [nt]

Great profile shots HTSE I’m glad I have the AP 15202 which houses this marvel movement [nt]

The 15202 is indeed a very well done "tribute". Thanks to the use of the 2121 it has the one attribute which I love on the 5402: no seconds hand.
