Swiss luxury watchmaker Franck Muller have launched a limited edition AC/DC watch to celebrate the band's 50th anniversary. Just 100 timepieces have been produced – 50 in polished stainless steel and 50 in black brushed titanium – with each retailing at just $9000 (£7000). Presumably, they're not available at the band's European pop-up stores this summer. https://www.franckmuller.com/
