Seiko Stopwatch Crystal – round, highly domed – approx. Ø 40.95 mm – acrylic – Vintage Stopwatch Crystal – NOS

Original watch crystal for a Seiko stopwatch (セイコーストップ / “Seiko Stop[watch]”) from unused Japanese new old stock (NOS), from the inventory of an old Tokyo watch parts dealer (中西商店 / Nakanishi Shōten, Tokyo-Shinagawa).

This is a large, round, high-dome crystal with a diameter of approx. 40.95 mm – the characteristic format of classic Seiko hand stopwatches. Seiko is one of the most renowned stopwatch manufacturers (official timekeeper of the 1964 Tokyo Olympic Games). The dealer bag is marked 17型 (Type/Size 17) and 26番 (No. 26).

Offered by exact measurements. The crystal itself is unused, clear and without scratches; signs of age are only found on the old dealer packaging.
