Vintage Seiko ladies dress watch with a gold-plated asymmetrical half-moon case and white dial on a two-tone bracelet of gold-plated links set with polished steel marquise inserts. The case curves around the dial in a single sweeping line that twists into the bracelet at both ends, framing a dial with applied gold dot markers, a baton marker at twelve and slim gold hands. The bracelet closes with an unusual rotating clasp signed Seiko.

Specifications

Movement: Quartz, made in Japan
Calibre: Seiko 1F20
Model reference: 1F20-6C90
Caseback: Stainless steel, serial number engraved on the caseback
Case width: 1.5 cm excluding the crown
Total length: 21 cm, fits a wrist up to 20 cm
Box: Dark red velvet presentation box (not original)

Condition

Battery fitted, the watch is running and keeping perfect time. In very good cosmetic condition, with the gold plating intact throughout. Some scratches to the caseback and light marks of wear on the metal parts. The glass is in good condition. The baton marker at six o’clock appears to be missing, likely having come loose over time. Please refer to the photographs.

Frequently asked questions

Are your watches authentic?

Yes — all watches sold in our shop are 100% authentic vintage pieces. We carefully source our timepieces from trusted auction houses and long-term, reputable suppliers. We never sell fakes or replicas.

Does my watch come with its original box and papers?

Every item included in your order is individually photographed and described in the listing. When original packaging or documentation is available, it will always be clearly shown and described. This means that if an original box, papers or any other accessory is not pictured or mentioned in the description, it is not part of the order. In this case, the watch will arrive in a Finchley Watches cardboard box, carefully wrapped and packaged for safe delivery.

What is your return policy?

We accept returns and exchanges within 14 days of delivery, provided the watch is returned in its original condition. The buyer is responsible for return shipping costs, initial shipping costs are non-refundable, and a flat restocking fee of 5% of the purchase price will apply. If the piece is faulty or significantly not as described, we will of course cover all return fees.

Do you ship internationally?

Yes — we offer free worldwide shipping from the UK. We usually dispatch within 2 business days. UK delivery takes 1–4 business days, international delivery 3–10 business days depending on your location. If you're ordering from the United States, all taxes and duties are included.
