Zenith Port Royal Manual Winding Chronometer ( Cal 135 ).
Credit picture: Antiquorum.

Very much my taste, even if I prefer versions with simpler dials. Though, what's not to love, here?
The case has a good 36 mm diameter, the dial is charming, the movement is great.
And... It is one of the rare manual winding chronometer wrist watch!
The kind of stuff I am hunting...
Best,
Nicolas
