====== Seiko 63RW ======
**Type 63RW** was the last mechanical [[railway watch]] produced by [[Seiko]]. Produced only between [[1978]] and [[1980]], the National Railway adopted the quartz [[Seiko 75RW|Type 75RW]] instead.

===== 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 It had been updated over the years, notably from 7 to 15 jewels and with [[hacking seconds]], but was outdated by the 1970s.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, the [[Seiko 61RW|Type 61RW]] using [[Seiko 6100|Cal. 6110A]], and this was the standard until [[1980]].

As Seiko gained confidence in their [[quartz]] movements, they began developing a quartz model, the [[Seiko 38RW|Type 38RW]]. But this was not adopted and production began and ended in [[1976]]. [[Seiko 75|Cal. 7550A]] was a more modern third-generation quartz movement and was adopted for the next railway watch, alongside this mechanical model, which used [[Seiko 63|Cal. 6310]]. Despite offering lower accuracy than [[Seiko 38|Cal. 3870A]] (15 seconds per month rather than 10), Cal. 7550A boasted longer battery life and cheaper construction and was more accurate than the mechanical alternative. The railway adopted [[Seiko 75RW|Type 75RW]] in [[1980]] and this model was discontinued.
