Seiko Dolce 5S21-6030 Sweep Second Tungsten Carbide White Dial

This 1989 Seiko Dolce 5S21-6030 combines a unique movement with exceptional case craftsmanship. Powered by the 5S21 quartz movement, it stands apart from typical quartz watches with its smooth sweeping seconds hand, a motion that closely mimics a mechanical watch. Many consider the 5S21 an early step toward Seiko’s later Spring Drive technology.

Adding to its appeal, the watch features a tungsten carbide case, an advanced material with a remarkable hardness of 2600Hv, harder than sapphire and second only to diamond. It is paired with a vintage style domed sapphire crystal, enhancing both durability and elegance.

Designed for the Japanese Domestic Market (JDM), this Dolce showcases a refined two-tone round case and a clean white dial. Measuring 35mm in diameter (including crown) and 37mm lug-to-lug, it wears comfortably with its integrated bracelet that fits wrists up to approximately 18cm.

The watch remains in excellent overall condition, showing only minimal wear on the bracelet. The case, dial, and crystal are all clean and well-preserved.

A rare and collectible Seiko, the Dolce 5S21-6030 blends innovative technology with a highly scratch-resistant case, a perfect balance of refinement, durability, and timeless vintage charm.
