The 18k Portofino Moonphase. 46mm case, around 8mm thick, an enamel dial and beautiful moon! What is there not to love? ...  

I recall a revival looking something like this and housing a hand-wound movement with an extra-long index and engraved bridges, but I may be conflating a few references. Anybody remember?

It too was 46mm, but thicker (11mm) than the 5251. Nico posted about this reference several years ago. www.watchprosite.com

And the layout of the moon subdial at 3 o’clock is so rare.

Everything else about them I do love.

Given its 8mm thickness (or should I say thinness), it actually fits very well and comfortably on my average size 17mm wrist.

I have the thickness at 95mm. Did you measure yours? If it is really 8 I want to update my data. Thx

Love this layout, but 42mm instead of 46mm would be my preference. There’s one for sale in the market now, but no original warranty card, box, etc.

It really is an elegant watch.

It could be the dial of a 19th C. Regulator Clock. Thanks for sharing.

This is one of the top IWC in my list!
