There is a great photo of Italian Sartorialist icon Gianni Agnelli in the December Town & Country. As all Sartorialists know, Gianni was well known for his for his quirky but very refined taste.
His watch-outside-the-shirt-cuff is well documented but what struck me about this photo was the watch itself. It's not a Rolex or some other big name watch but a digital watch! I would love to think it is a Casio.
The photo is from 1980 so maybe a digital watch had a little more allure then but I love and Gianni is remembered for not being afraid to mix high-end/low-end or craft/tech.
So ,with this as evidence, don't you think Gianni ,if he were 50 years old today, would be using a cellphone as his watch? I just hope he wouldn't be wearing it on his belt!
