The essence of the Seiko Presage Style 60s collection is vintage style, which continues with the ‘road trip’ theme of this model, inspired by the iconic 1960s cars; their wheels, levers and instruments and colour scheme. Its hairline finishing gives it a machine-like feel, whilst the new GMT dial layout incorporates the details of the original Seiko 1964 crown chronograph. This petrol blue colour design operates on a 4R34 mechanical calibre movement, and has a GMT function, allowing multiple timezones to be tracked at the same time.
