Atomic wall clock Unilux WAVE Round Black, 30 cm diameter, battery AA, 1.5 V

The Unilux WAVE Round Black atomic wall clock is a 30 cm diameter timepiece designed for accurate, hands-free timekeeping in offices, classrooms and public spaces. Radio-controlled synchronization ensures the clock automatically sets itself by receiving the official time signal, providing long-term precision without manual adjustment. The clock runs on a single AA 1.5 V battery (not included) and features a compact, lightweight construction with a slim black frame and large high-contrast numerals for clear readability from a distance.

Advantages

Radio-controlled timekeeping maintains synchronization with the official atomic time source, eliminating manual setting and minimizing drift. The simple, sober design with a fine black frame integrates with a wide range of interior styles while keeping visual distraction to a minimum. Large black numbers on a white dial improve legibility up to approximately 35 meters, and the low weight facilitates easy mounting and repositioning. The clock’s standard 30 cm diameter and unambiguous dial layout make it suitable for both individual rooms and larger shared spaces.

Suitable for

• Offices and meeting rooms where accurate, self-setting time is required
• Classrooms and lecture halls for clear time visibility during lessons
• Reception areas and corridors in public buildings

How to use

Install a fresh AA 1.5 V battery into the clock following the polarity markings. Mount the clock on a secure wall hook or screw at eye level for optimal visibility; the clock’s lightweight design simplifies hanging and repositioning. After battery insertion, allow a short period for the radio signal reception; the clock will automatically adjust to the official time. If needed, place the unit away from large metallic structures or heavy electronic interference to improve signal reception.

Usage recommendations

For reliable radio synchronization, position the clock with a clear path to the signal source and avoid placing it directly beside large metal cabinets or dense electronic equipment. Replace the AA battery annually or when the movement shows signs of slowing. Clean the clock face with a soft, dry cloth to preserve dial contrast and readability.
