In 2018, Mayer made a guest appearance in an episode of Hot Ones where he was seen wearing a Rainbow Daytona, reported Showbiz Cheat Sheet. Mayer’s Rolex Rainbow features 11 baguette-cut rainbow-coloured sapphire markers and 36 baguette-cut sapphires surrounding the bezel, states the source.The timepiece retails at around US$97,000, but on the pre-owned market, the watch can range between US$450,000 to US$1 million, according to The Watch Box.

2. Audemars Piguet Royal Oak Selfwinding Flying tourbillons finished in titanium

Mayer flashed what appears to be a 41mm version of the Audemars Piguet Royal Oak Selfwinding Flying Tourbillon when he performed at the SOB Rock Tour 2022, as per Robb Report. Instead of featuring Audemars Piguet’s signature Grande Tapisserie dial with the square motif, the model showcases a sandblasted smoked blue face, states the source.

The timepiece also distinguishes itself with a self-winding Caliber 2950 movement combining a flying tourbillon with a central motor, according to the report. This Audemars Piguet Royal Oak is worth US$280,000, as per USA Luxury Watches.

3. Audemars Piguet Royal Oak Offshore Selfwinding Music Edition

Mayer combined his passion for music and watches when he was spotted wearing a 43mm version of the Audemars Piguet Royal Oak Offshore Selfwinding Music Edition, as reported by Superwatchman. According to the Audemars Piguet website, the watch showcases a Tapisserie dial resembling an equaliser.

The knurled-textured studs look like jack plugs and the crown guards mirror a terminal fader, states Superwatchman. This model is estimated to be at US$229,000, as per NYC Watcher.

4. Audemars Piguet Royal Oak Perpetual Calendar

Mayer made the model look cooler when he wore it with his tattoos. The Audemars Piguet Royal Oak Perpetual Calendar features the day, date, month, astronomical moon and week of the year, as per the luxury brand’s website.

The Grande Tapisserie decorated dial also indicates the leap year, a function pioneered by the luxury brand in 1955. The timepiece is valued at around US$90,000, as per Hodinkee.

5. Rolex White Gold GMT II “Pepsi”

Mayer isn’t afraid to wear a pop of colour – especially if it’s a Rolex. The timepiece is named “Pepsi” due to its signature red and blue bezel, per Superwatchman.

The classic luminescent hour markers and red hour marker alongside the new 18k gold Oyster bracelet and matching clasp gives the “Pepsi” Rolex a much more luxurious feel. The watch is priced at US$40,000, as per Swiss Watch Expo.

6. Rolex Submariner “Smurf”

The “Smurf” was the first Submariner to feature a case and bracelet made from 18k gold, according to The Watchbox.

7. Rolex Daytona green dial

Mayer spoke about his own Rolex Daytona green dial and its potential on Talking Watches 2 in 2019.

In an interview with watch website Hodinkee, Mayer enthused about his own Daytona and called it “sleeper hit”. This generated hype among collectors and drove the retail price up from US$34,650 to as much as US$85,000, per reports.

According to The Collector’s Circle, the watch comes with a sunburst green dial and features 18-carat gold-hour markers with Chromalight.
