While Rolex’s headquarters and final assembly are in Geneva, its largest production site, where all its movements are made, is in Bienne. The facility, hosting 3,000 employees over multiple buildings, is highly impressive. While it cannot be visited, the glass windows enable an insight into Rolex that is almost surprising given the brand’s reputation for secrecy. While not worth it for everyone, die-hard fans will enjoy a stroll around, especially on a weekday when the teams are at work.
