Casio early digital watches in mid '70s, the Casiotron. The earliest ones were all plain vanilla time telling units, and mostly pretty chunky. The one in photo, could be classified as their second generation of LC watches. From information on the internet, this is the their first model to have the alarm feature equipped.
Came as a non-runner, works fine after taking it apart for a careful cleaning on all contacts and clean off some residues caused by acid leakage from the dead battery. Original bracelet is included and shines again after several rounds of ultrasonic baths and light polishing.
A welcome piece to my vintage collection indeed.
