What is Zaratsu Polishing?

Zaratsu is a highly skilled, manual technique performed by only the most experienced Takumi master craftsmen. The technique involves pressing the watch case against a rotating tin plate at specific angles to achieve a distortion-free mirror finish and razor-sharp edges where this mirror finish meets the brushed surfaces.

The “Sparkle of Quality”

This interplay of perfect light reflection and sharp edges is known as the “Sparkle of Quality.” It is the design philosophy that ensures the watch is readable even in low light, as any available light source is reflected dramatically off the polished surfaces and indices. On a pre-owned Grand Seiko, the condition of the Zaratsu polish is a direct indicator of authenticity and care. If the surface shows waves, softness, or inconsistent reflections, it is either poorly maintained or, more likely, a counterfeit.
