Rare Vintage Casio W-770 Men’s AlarmChronograph Digital Sports Watch JDM 1980s

Up for sale is an extremely rare vintage Casio W-770 men’s digital sports watch produced for the Japan Domestic Market (JDM) during the 1980s and powered by Module 548. This model is one of Casio’s most elusive early sports designs and is widely regarded as a foundational reference that influenced the later evolution of the G-Shock line. The sound is not working on the watch. It does appear to function if the case back is left very loose. The exact issue is unknown. Beyond this the watch is in full working condition and all other features and functions are operating properly. All parts of the watch are original including the stainless steel bracelet. The watch is in great physical condition but has signs of use and age. The photos best describe its physical condition and should be reviewed carefully. This is an exceptionally rare and highly desirable Casio seldom seen on the market. A strong example for collectors and vintage digital watch enthusiasts and a historically important design in Casio’s sports watch lineage.
