Original Seiko replacement dial from the luxury dress line DOLCE, caliber 6730, Seiko part no. 67300370 (dial code "JAPAN 6730 ⚡ C370 R"), manufactured by Hattori Seiko Co., Ltd. (Seiko), Japan. Unused original part (New Old Stock, NOS) in the original Seiko "WATCH PARTS" blister pack.

The round dial features a noble, gold-colored sunburst finish with applied, polished gold indices (long baton indices, double index at 12) and fine printed minute track. Below the 12, the inscription "SEIKO QUARTZ", above the 6, the characteristic line name "Dolce" in a curved font; at the bottom edge, the factory designation "JAPAN 6730 C370 R" with a Quartz lightning symbol. Pure time dial (central hands), no date aperture - simple, flat, exceptionally elegant.

A sought-after original part for collectors, watchmakers, and restorers who wish to authentically restore a Seiko Dolce caliber 6730 - including the high-quality (partially 10K gold) case variations.

Historical Context: Seiko "Dolce" and the Dress Prestige Line

From the early 1980s, Dolce (along with its ladies' counterpart Exceline and the top line Credor) carried Seiko's luxury dress ambition into the quartz era - an ambition for the finest, flat dress watches previously established by the mechanical icons King Seiko and Grand Seiko. While King Seiko/Grand Seiko embodied mechanical dress prestige, Dolce stood for ultra-flat quartz elegance at a high level. The caliber 6730 is designed precisely for this: an extremely flat analog quartz movement that allowed case heights of sometimes only ~3.5 mm.
