Dimensions The case measures 37 mm in diameter, excluding the recessed crown, providing a substantial yet comfortable fit that wears well by modern standards while retaining its vintage charm. Remarks The Seikomatic 6206-8080 is a visually compelling reference, largely due to its separated day and date windows which create a pleasing vertical symmetry on the dial. The combination of the sunburst finish, faceted indices, and fluted bezel makes this a versatile piece that easily transitions from formal to casual settings.

The 6206 caliber specifically became known for its reliable day-date functionality, paving the way for the legendary 62-series movements that would eventually power some of the brand's most prestigious chronometers. This specific model reflects a period of immense creativity and technical progress for Seiko on the global stage. / Second Vintage SKU: SEI-SMJ-0019
