Seiko Dolce 7321-6170 Tank Tungsten Carbide Two Tone Champagne Textured Dial

Before ceramic and sapphire are used as scratch resistance material in watches, Seiko experimented with tungsten carbide in the 1980s in their high-end Dolce range and a limited Grand Seiko SBGT009 in 1988.

The tungsten carbide has a hardness of 2600Hv which is harder than sapphire and only second to diamond.

The difficulties of engineering and machining requirements are why no tungsten carbide watch is produced today, making the Seiko Dolce tungsten carbide series a rare watch and worth collection.

The 1988 Seiko Dolce 7321-6170 showcases an elegant and refined aesthetic, featuring a beautifully faceted two-tone case with a silver outer frame and a gold-tone bezel. The champagne-textured dial adds a touch of sophistication, complemented by its slim indices and the rare presence of a second hand—setting it apart from many other Seiko Dolce models.

Designed with a classic tank-style silhouette, this timepiece exudes vintage charm and is an excellent choice for formal occasions. The watch remains in outstanding condition, with no visible signs of wear, a pristine dial, and a scratch-free sapphire crystal.

Thanks to Seiko’s high-quality craftsmanship, the sharp lines of the case are well-preserved, and with proper care, it is expected to retain its crisp and polished appearance for years to come. This vintage Seiko Dolce is a stunning collector’s piece that blends timeless design with everyday elegance.
