====== Seiko 38RW ======
**Type 38RW** was the first [[quartz]] [[railway watch]] produced by [[Seiko]]. It was only offered in [[1976]] and failed to gain adoption. Instead, Seiko's mechanical [[Seiko 61RW|Type 61RW]] was replaced by the quartz [[Seiko 75RW|Type 75RW]] in [[1980]].

===== Overview =====
Seiko had produced [[railway watch]]es since [[1929]], with the [[Seiko Type 19|Type 19]] becoming famous across Japan and seen in every railway cabin. It had been updated over the years, notably from 7 to 15 jewels and with [[hacking seconds]], but was outdated by the 1970s. The Type 19 was discontinued in November, [[1971]]. In [[1972]], Seiko began producing a railway watch using [[Seiko 6100|Cal. 6110A]], and this was the standard until [[1980]].

As Seiko gained confidence in their [[quartz]] movements, they began developing a railway watch. The result was the 38RW, which used [[Seiko 38|Cal. 3870]]. This was a descendant of Seiko's first mass-market quartz movement and represented a significant upgrade to the 21,600 A/h mechanical Type 61RW. Accuracy was rated at +/- 10 seconds per month.

The Type 38RW was not adopted by the National Railway, however, and production soon ended. Seiko turned to the new [[Seiko 75|Cal. 7550A]] in the [[Seiko 75RW|Type 75RW]] for their next quartz railway watch, and this would replace the Type 61RW soon after introduction in March, [[1978]].
