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.
Such as this Seiko Dolce tank 7741-5130, which has an integrated bracelet that fits measurements within +/- 17.5 cm and a gorgeous two-tone salmon dial with shimmering shines under certain lighting conditions. The watch also has sword-shaped hands and gold Roman indices. The sapphire crystal and tungsten carbide casing of the watch have kept it in excellent condition overall.
With proper care, you will be assured a crisp case that will stay almost scratch and wear-free for the foreseeable future.
