John Mayer wears Casio G-Shock watches

Musician John Mayer is a serious watch enthusiast who has been described as “the world’s most influential watch collector.” While many of his timepieces are of the vintage and super-expensive variety, he is also a fan of Casio G-Shock watches.

Recently, Mayer has been wearing a G-Shock GWG-1000-1A Mudmaster in his “Current Mood” video series on Instagram TV. He also shared a photo of the newly released NASA x G-Shock DW5600NASA20-7 collaboration watch in Instagram Stories. A few months ago, he was spotted wearing a G-Shock GG-B100-1A9 Mudmaster during a performance.

This isn’t a surprise, as Mayer has admitted to being a G-Shock fan in the past. He wrote about liking the G-Shock Frogman and mentioned shopping for vintage G-Shocks on eBay.

“I love Patek Philippe perpetual calendars only marginally more than I dig the Casio Frogman G-Shock – but for different reasons – and if you’re wearing either, chances are I’ll sidle over to you and start a conversation about it.” – John Mayer, 2012, from
