... PN dials of the 1960´s. Spectacular. I´m specially fond of the gold dial of the Seiko Pogue. Your example looks in a wonderful condition including original bracelet.
I also own both a Hulk Sub and a similar Panerai GMT which enjoy so much.
Finally your Calatrava epitomizes the elegance and simplicity of a lovely Patek and the meaning of "sometimes less is more" expression.
Thank you for your great entry my friend. Hagwe! Abel
