A throwback to a flagship design from 1978, the retro-tinged PRX automatic watch from Tissot has made a welcome comeback. Crafted from polished stainless steel with scratch-resistant sapphire crystal for protection, this style is designed with an innovative, trend-led geometric blue dial. Oh, and there's no secret as to how the brand pieces it together as it's fitted with an exhibition case back – so you can take a peek at the Swiss automatic movement.
