I stopped wearing watches as soon as I had a mobile phone small enough to fit in my pocket. Landlines have gone the way of bustles and buggy whips for most individuals.
You may be right, watches don't get calls from scammers. Having said that, a smartphone is a far more versatile and functional device than a watch. I have about 600 books and 1000 music files on my mobile. Calculator, calendar, voice recorder, internet-capable, translator - enough said.
