Audemars Piguet

I think there are at least a few. One of my go to summer watches that always finds its way into my travel case. ...  

39mm 15300 is the perfect size imho. Yours look great on you. Love the blue dial ! Cheers Robin ...  

And I agree the blue is something special. The color shifts in all kinds of light. Sometimes looks black, sometimes navy blue, sometimes gray and sometimes royal blue. I’m really happy to have the blue too because they seem to be a little hard to come by.... 

...  

I got this one not long after they were introduced. It doesn't get the wrist time these days that it once did, but it's still the best proportioned of the 15xxx watches and closest to the original Jumbo design. ...  

But at my request AP changed it to blue when it was in for service. They returned it with the original dial as well.

I did, starting in 2006 for almost 2 years. I loved the watch.
