A vintage Seiko half-moon ladies' dress watch in gold-plated finish. The dial is dark mother of pearl — appearing near-black in flat light, shifting to a deep iridescent blue when light catches it at an angle.
For a piece of this age, the condition is exceptional: plating fully intact, crystal scratch-free, and the dial surface unmarked. This particular combination of the half-moon silhouette with a mother of pearl dial is genuinely rare to find in this state.
The case follows the asymmetric triangular form characteristic of Seiko's half-moon series, with a deeply ridged fan bracelet integrating directly into the case on both sides. No date. Comes with the original Seiko presentation box in burgundy velvet.
Case width: 19mm including crown
Bracelet length: 17.6cm, suitable for wrists up to approximately 16.6cm.
Links can be removed to reduce length.
Reference: 1N00-5E09
Movement: Seiko quartz calibre 1N00
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.
