Up for sale is an extremely rare vintage Casio Marlin WS-730 men’s digital alarm chronograph sports watch from the 1980s, produced for the Japanese Domestic Market (JDM) and powered by Module 145. This highly collectible Marlin-series model reflects Casio’s innovative digital watch designs of the era and features the iconic Marlin fish logo along with the distinctive bolt-style lettering on the front bezel, a design element widely considered a precursor to the bold graphic styling later seen on early G-Shock models.
The watch is in full working condition and all features and functions of the watch are working properly.
The watch is fitted on its original Casio stainless steel bracelet.
The watch is in good physical condition but has signs of use and age. The photos best describe its physical condition and should be reviewed carefully.
The Marlin series remains one of the most sought-after lines of vintage Casio digital watches, and the WS-730 is an especially difficult model to find today.

► ARCHIVE FILE: CASIO — BRAND HISTORY
Casio began not with watches but with calculation. Tadao Kashio founded Kashio Seisakujo in Tokyo in 1946, and with his three brothers developed the 14-A in 1957, the world's first compact all-electric relay calculator, incorporating the business as Casio Computer Co. that same year. The move into watchmaking came in November 1974 with the Casiotron, a digital watch whose claim to fame was an automatic calendar that knew how many days each month had, a small feat of logic that announced how an electronics firm would approach timekeeping.
