Hi Francois
I laughed out loud at your Hippie comment. Although I was born at the time this Seamaster was in the Omega model range, those who know me would in no way describe me as a hippie, but thanks for the compliment!
The shirt is an Akira Isogawa design and yes, I did choose it to go with the watch; both the colour and the aesthetic seemed to fit.
Thanks for noticing the shirt and I hope it set off the watch in a different way.
Regards
Andrew
