The CASIO Collection STANDARD A158WA-1JH is a Japanese Domestic Market digital watch featuring a classic rectangular design and a stainless-steel bracelet. Its lightweight construction, straightforward digital display and practical everyday functions make it a versatile unisex model.
Classic Digital Design
The compact rectangular case is paired with a traditional positive digital display and a silver-tone stainless-steel bracelet. Its long-selling design complements casual clothing, workwear and vintage-inspired styles without appearing overly complicated.
Adjustable Stainless-Steel Band
The stainless-steel band uses a free-adjust clasp that allows the fit to be adjusted without removing bracelet links. The watch weighs approximately 46 g and has a slim 8.2 mm case thickness, supporting comfortable everyday wear.
Practical Everyday Functions

Green LED Backlight
A green LED backlight helps illuminate the digital display in dark surroundings. The watch is also rated for everyday water resistance and provides an estimated battery life of approximately seven years.
Japanese Domestic Market Model
The A158WA-1JH is the current Japanese-market reference that replaced the earlier A158WA-1JF. According to CASIO, the model-number change did not involve any change to the product specifications.
