Casio W-738H-1AV

Lock into high-efficiency utility with the Casio W-738H-1AV. Shunning delicate aesthetic trends, this sports-minded digital watch introduces a muscular, square-faced frame engineered specifically for "everyday wear and active use." Wrapped in a stealthy, matte black resin housing with a tactical accent color on its dedicated control button, it serves as a highly reliable companion for sports, work, and intense daily life.

The defining characteristic of the W-738H is its advanced Vibration Alarm system. Instead of relying solely on an audible chime that can be easily missed in noisy environments, the watch physically vibrates against your wrist to alert you of daily alarms, hourly signals, and countdown timer expirations. To optimize this, the strap is uniquely designed with a shorter hole pitch, allowing for ultra-fine sizing adjustments to keep the case back snug against your skin so you can easily feel every alert.

Key Features

• Tactile Vibe Alert Engine: Provides discrete, silent physical vibrations on your wrist for the daily alarm, hourly time signal, and countdown end-times—ideal for loud job sites or quiet meeting rooms.
• Legendary 10-Year Battery Life: Equipped with an ultra-low-consumption system powered by a heavy-duty CR2032 coin cell, ensuring an incredible full decade of "long life battery" performance.
• Dedicated Mode Controls: Features an explicitly identified, color-accented start/vibrating activation button alongside a prominent front-center light pusher that is highly responsive and easy to press even while you are in constant motion.
• 100-Meter Water Resistance: Backed by a robust 10-bar depth rating, making it completely resilient against swimming, showering, surfing, and heavy tactical mud navigation.
• High-Brightness LED Backlight: Floods the expansive screen with a high-contrast amber glow, making all vital tracking data exceptionally "easy to see in darkness."
• Dual-Zone Timing Toolkit: Outfitted with a 24-hour countdown timer, an alternate dual-time mode for travel tracking, and a 1/100-second stopwatch featuring a specialized 5-second auto-start countdown.
• Balanced Mid-Size Silhouette: The lightweight 43 g resin shell measures beautifully at 42.8 mm wide, providing a commanding, legible layout that sits completely naturally for all-day comfort.
