This is a Seiko Elnix from 1974. It has a snow white dial with markers that flash gold when the light reflects from the applied gold Elnix logo. It is quite the rarity, and just look at that solid link bracelet!
In the short period between 1957 and the mid 1970s Electric Watches reigned. Seiko had five series of these movement calibres, with the Elnix marked as the last Emperor; the most advanced and last transistorized electric watch. The watch on sale here, the 0703-7060, was among the last series of Elnix, it came out of the Seiko factory in 1975. On the dial is the gold colour Elnix logo spiraling upward arrow-style (symbolizing electricity). Underneath the nostalgic logo is the historic symbol of Daini. The watch is equipped with day-date functions, it also has a smooth sweeping second hand (!) which is a dead give away that it is not a quartz, but to confuse matters, it is also not an automatic...
The fact is, this watch is powered by the 16 Jewels 0703A movement, and a 1.55 volt Silver Oxide Battery breaths life into the movement, not a rotor or a hairspring. It has a frequency of 4 Hz and an amplitude of 8 beats per second or 28,800 bph. That puts it in the same league as a chronometer1
As these watches still use a balance-wheel they should not be confused with quartz-controlled movements or Bulova's Accutron "tuning fork" technology. They are an important milestone; and most of them still run problem free.Manufacture: Seiko
