Casio W-738H digital watches with vibration alert and 10-year battery life launch in 2026

Casio has unveiled its new W-738H series of digital watches, set to hit the Japanese market in May 2026. The lineup features two variants: the Casio W-738H-1AJF in black and W-738H-3AJF in khaki green.

The W-738H models largely build on the previous W-735H series but come with a fresh square case measuring 47 × 42.8 × 13.5 mm, giving them a more modern profile while maintaining rugged durability.

Casio’s new W-738H digital watches have already appeared in European retail channels and on Casio UK’s website, priced around £45. The official European and UK release is expected in June 2026.

Key features of the Casio W-738H include:

• Dual timezone display
• Stopwatch with 1/100 second precision, including lap timing and auto-start
• 24-hour countdown timer
• Daily alarm and hourly chime
• Auto calendar up to the year 2099

Perhaps the standout update is the addition of a vibration alert alongside standard sound notifications-a rare feature in digital watches at this price point. The W-738H also boasts a battery life of up to 10 years and 100-meter water resistance (10 bar), making it a handy companion for both everyday and outdoor use.

In Japan, each W-738H model is priced at 7,700 yen (~$56). Pre-orders are already open on Casio’s official website.

Casio’s W-738H series competes with budget-friendly digital watches from brands like Timex and entry-level G-Shock models. The combination of vibration alerts and a decade-long battery life makes it a compelling choice for users who want low-maintenance, durable timepieces without breaking the bank.

Watch for Casio to further integrate hybrid alert systems and long-lasting batteries into its mainstream lines, blurring the line between traditional digital watches and more advanced smartwatches in the years ahead.
