The Seiko ELNIX, model number 0703-7070, is a curious piece of horology as the last electric watches with balance wheels ever made by Seiko.


From the serial number on the case back we can accurately date this watch to being made in October 1974.


The first watches to utilise electronic components appeared in the 1950’s.  Then the Bulova Accutron was launched in 1960.  Citizen launched their Cosmotron in 1966, and then Seiko joined in with the EL370 in 1967.  Seiko then changed the game in 1969 with the first Quartz watch, which should have killed off the transistor balance wheel movement, and it did.  But before it died Seiko continued to develop the technology, and their final models featured the 0703 movement we have in this watch.

This example is far more subtle than most of the ELNIX models, lacking the bold colour dial and faceted crystal.  It could be that the faceted crystal has been replaced with a flat glass, as the faceted ones are not only difficult to find but also difficult to read.  The watch is in great condition, and it is difficult to fault the case, glass or dial.  Both day and date can be quickset via the crown, and the day wheel is in Kanji and English.  The movement runs at 28,800 bph, and is keeping very good time.  This watch has something for so many collectors – Seiko collectors will love the rarity, Electric watch movement collectors will want the technology, and all vintage watch lovers will admire the condition.

This watch will be supplied with our Certificate of Authenticity.
