The vintage Timex 400 series of watches were produced in just 2 years, 1960 and 1961. Vintage watches in the Timex 400 series are unique in the vintage Timex range in that they do not have in-house movements. Instead both a Japanese Saitoshi and German Durowe 17 jewel movements were used. Saitoshi was the precursor to Seiko. This gives the Vintage Timex 400 series a special pedigree and makes them highly collectible and sought after by collectors. As a result, Timex 400 watches command a higher than average price.

If you are in the market to collect vintage Timex 400 watches make sure that the dials are clean and without any damage due to water ingress. This is common in the vintage Timex 400 and is usually found either around the edge of the dial or expanding out from the center.
