Vintage Seiko ladies’ automatic wristwatch, reference 4205-0170, featuring a blue sunburst dial, silver stainless steel case, and new replacement black leather band.

The blue dial catches the light with a subtle radiating finish and features raised silver-tone baton hour markers, a double marker at 12 o’clock, and a framed date window at 3 o’clock. Silver-tone hour and minute hands complement the markers, while a slender central seconds hand completes the classic design. The dial is signed “Seiko Automatic” and “17 Jewels.”

Powered by a Seiko caliber 4205 mechanical automatic movement, this watch winds through normal wrist movement and also supports winding by the crown. No battery is required. The watch is currently running well. Exact daily accuracy and full power reserve have not been formally measured, and service history is unknown.

The stainless steel case has a polished fixed bezel and tapered lugs. The caseback is marked “Seiko,” “Water Resistant,” “Stainless Steel,” reference 4205-0170, and serial number 282264. Estimated production is circa 1982.

Pre-owned vintage condition with scratches and wear from age and previous use. The crystal shows visible scratching, and the case has surface marks. Some marks over the dial may be on the crystal; please review the close-up photographs for the overall appearance. A new replacement black leather band is included and fitted to the watch.

Although the caseback is marked water resistant, current water resistance has not been tested or guaranteed. Please review all photographs for condition and included items.
