The core idea is a hand wind chrono based on the caliber CH 29-535 PS and using the hobnail bezel case of the Ref. 5139G.
Yesterday I've posted a first proposal (here), today I'd like to show a new one, with a design strictly derived from the 5139G.
I've made a search on the internet, but I haven't found nothing like this and I'm wondering if, in the current PP line-up there could be space for such a timepiece; who could say "no"?
Do you like it?
Ciao!

It can work on a simple watch, such as a Calatrava.
Best,
Nicolas.
In november 2010 I've posted a proposal about a 5170 with white metal case, but I totally agree with your suggestion: a blue dial would be just gorgeous.
First version (november 2010, inspired to an old PP chrono).

Second version (same vintage style, with pulsometric scale; all the writings are printed in white, the hour/minute/small seconds hands are in white gold, the chrono hands are white painted).

Third version (did you had in mind something like that? if not, could you write me a detailed specification? personally, I find that this design has a certain déjà vu and that it isn't recognizable as a true modern Patek Philippe, even if I have pictures of an old PP reference having a similar layout).

Fourth version (as above, but with enlarged subdials and without number 3-4-8-9).

Good night!
It's me I have to thank you for your comment!
To design a watch is indeed very hard. It's not only about finding the best solution for a given need, but a true expression of personality. I'm only a watch-lover with mediocre computer skills and I think that the PuristSPro community, with its very skilled aficionados and serious collectors could (and have to) talk about and promote every new trend in the horology world. For example, didn't you find exciting the experience we had in the AP forum about a Royal Oak equipped with Star Wheel movement?
Ciao!
I like the first 2
But I'm not a fan of these sunken subdials. (I know the movement is made this way) but for me they should be alligned at 3 and 9 o'clock
I find the position of those subdials more suitable for contemporary-looking timepieces, than for classical ones. It's my personal opinion, of course, and I'm sure PP will find excellent aestethical solutions even with this new chrono dial layout.
Ciao!
A million of styles, versions, aestethical messages.
Choices come one after the other, endlessly.
Ciao!

I have to be fully honest: I'm still not completely satisfied by my proposals and I'll try to add a touch of boldness. Please, keep in touch, your opinion are not only welcomed: they're the forum's soul!!!
Ciao!
Calm down, please, there's no need to scream, triplebridge. I'd be very happy if you would like to discuss your point of view. Thank you for your attention.
Ciao!
.. its not that bad.. good job on the creation... but its not the best looking watch... its a schizophrenic watch.. trying to be both dressy and sporty but ultimately too much of both and cant work either way... doesnt make sense... but love the creations you come up with!
