Seiko LC Quatrz 0662-5009 is the an from early series of seiko lcd watches, this one produced in March 1976.
It is interesting to note that in these early modelst he contact between the display and the module is a full metal, graphite rubber was used on the later models.
On this watch is all original, this model is especially nice because it has white face. The magic that these first seiko lcd models have is fatal to me…
