Seiko Dolce 9521-5010 – High Precision Quartz (August 1982)

Elegant and ultra-thin vintage dress watch from Seiko 's exclusive Dolce line , known for its particularly high-quality quartz models of the 1980s.
This model, reference 9521-5010, embodies the era of early high-end quartz watches – minimalist, precise and perfectly crafted.

The two-tone rectangular case with gold-colored bezel, the graphically reduced grey dial and the striking narrow hands give the watch a timeless architectural elegance.
The “Dolce” collection was positioned in Japan as a premium line above the Seiko standard quartz models and was in direct competition with the Grand Quartz and Superior models of that time.

Inside, the precise Seiko caliber 9521A is at work, an ultra-thin quartz movement with temperature-compensated quartz oscillator – a technical masterpiece for the early 1980s.
