The Seiko Presage was the first watch that featured an enamel dial Seiko which was led by Mitsuru Yokozawa. After the advent of the enamel studded timepieces, the Presage collection expanded itself into various personas. Divided into two series, the Prestige and Basic, the Presage collection features various complications such as open heart, power reserve indicator and small seconds. One unique addition to the Presage collection is the tonneau-shaped Presage, the SPB049.
