Seiko Original Dial 4301-0010 "Seiko Quartz" (Tonneau, Roman Numerals, Gold) - NOS

Original Seiko replacement dial, dial/caliber code 4301-0010 (T), manufactured by Seiko (Hattori Seiko Co., Ltd.), Japan. Unused original part (New Old Stock, NOS) in its original Seiko "純正部品 / Genuine Parts" packaging.

The tonneau-shaped dial (curved rectangle) features a fine, gold-colored textured finish with black printed Roman numerals all around. In the upper half, the lettering "SEIKO QUARTZ" with the characteristic "SQ" emblem; at the bottom edge, the factory designation "JAPAN 4301-0010 T". Pure time dial (central hands), without a date window – a classic-feminine dress design from the early quartz era.

A sought-after original part for collectors, watchmakers, and restorers who wish to faithfully restore a Seiko Quartz caliber 4301 (tonneau ladies' model).

Historical Context: Early Seiko Quartz "SQ" (43-series)

The "SQ" emblem stands for Seiko Quartz. Caliber 4301 originates from the 43-series starting in 1975 – one of Seiko's first mass-produced analog quartz families, technically still executed with jewels and thus of higher quality than later economy quartz movements. Within the brand world, "SQ" ranks below the prestige quartz lines King Quartz and Grand Quartz, or the luxury dress lines Dolce/Exceline and Credor – those quartz successors to the claim that King Seiko and Grand Seiko had previously established mechanically. This ladies' tonneau dial belongs to the early, still ambitious chapter of this quartz history.
