High legibility is a vital attribute in a diving watch, and to ensure that the dive time is as readable as possible even in dark waters, SEIKO commissioned Isshu Tamura, a world-renowned lacquer artist to create a dial that is truly jet black. Each dial is painted, layer by layer, and then polished by hand by Mr. Tamura in his studio in Kanazawa on the western shores of the Japanese mainland. Isshu Tamura was born in Kanazawa in 1957, and is a master of “Kaga Makie” which is a traditional style of lacquer.
The legibility is further enhanced by the use of anti-reflective coating on the sapphire glass.
