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.
This Tank Dolce circa 1985 features a two-tone case with silver top and bottom and gold frame case tank, cabochon crown, classic champagne color dial, and one of the Seiko Dolce range that has the second hand—a classic beautiful two-tone case tank design for the collection.
With proper care, you will be assured a crisp case that will stay almost scratch and wear-free for the foreseeable future.
