I have been a one gal person and married my girlfriend from undergrad 15 years ago. Lately, I got her into appreciating automatic/mechanical watches.
To celebrate our milestone, I got her #seiko Alpinist. The watch is not only beautiful but can be worn by both.
I have recently started collecting watches, like 5 years ago. Love them for the art and engineering. And my wife doesn’t know how many watches I have.
