Vintage Orient SK Sea King 21J Auto Blue Dial Day Date 42mm 70s Mens Watch Box

A vivid electric-blue textured dial gives this vintage Orient SK Crystal an unmistakable 1970s presence. Combined with its angular stainless-steel case, exposed corner fasteners and contrasting black inner scale, the design is far more architectural and adventurous than a conventional automatic dress watch.

The dial is signed ORIENT – SK Crystal – 21 Jewels and features applied gold-tone baton markers, matching hands and a day-date display at three o’clock. The calendar shown includes Arabic script, adding another attractive detail to this particular configuration. Orange 15, 30 and 45 markings punctuate the black inner scale and reinforce the sporty period styling.

At approximately 42mm, the case wears large for its era and is complemented by a stainless-steel bracelet with an Orient-signed clasp. The multi-control case layout is characteristic of the original SK Crystal family, whose period design incorporated an adjustable inner timing scale.

Works well for a vintage timepiece.

The watch shows honest age-related wear, including scratches, rubbing and small marks across the case, bezel area, bracelet and clasp. The blue dial remains the visual highlight and retains strong colour and contrast. The historical water-resistance wording on the caseback should not be regarded as a current water-resistance guarantee.

A vintage Orient presentation box is included as photographed, but is not represented as confirmed original matching packaging for this specific watch.
