La Crosse Technology Atomic Digital Clock with Wireless Outdoor Sensor — Black, Moon Phase & Self-Setting Time

La Crosse Technology’s 513-75624-INT is a self-setting atomic digital clock that shows accurate time, outdoor temperature, and moon phase with optional tabletop or wall placement.

This compact black digital clock combines precise timekeeping with environmental context so you can plan your day quickly. It receives the atomic radio signal to set and maintain time automatically (including daylight saving adjustments if enabled), displays outdoor temperature via a wireless sensor, and features a moon-phase icon for a fast visual of the lunar cycle. Battery operation ensures the display and alarm keep functioning during power interruptions, and the simple controls let you switch between 12- or 24-hour format and Fahrenheit or Celsius.

How does the clock keep time accurate without manual setting?

The clock syncs automatically to the national atomic time signal and will update itself when required, including changes for daylight saving time unless you turn that feature off. You can also select one of seven time zones so the display matches your local time. This eliminates frequent manual adjustments and keeps seconds-accurate time even after batteries are replaced.

• Automatic atomic synchronization for second-level accuracy
• Daylight Saving Time auto-adjust with OFF option
• Seven preset time zones for regional alignment
• Battery-powered to retain correct time during power outages

What temperature and outdoor data does it provide?

The clock shows current outdoor temperature transmitted wirelessly from the included sensor, plus indoor temperature if you place the clock inside. The remote sensor communicates up to roughly 330 feet (100 meters) in open air, and the display can be toggled between Fahrenheit and Celsius. Temperature trend indicators help you see whether it’s warming or cooling at a glance.

• Wireless outdoor sensor included, ~330 ft (100 m) range in open space
• Displays temperatures in °F or °C with trend arrows
• Sensor reads up to 140°F for hot environments
• Low-battery alerts for both clock and sensor

Does it have alarm, display, and mounting options that fit daily use?

Yes — the unit includes a crescendo alarm with a 10-minute snooze, large 2-inch digits for easy reading, and an elegant black enclosure suitable for desks or walls. The display supports both 12- and 24-hour formats, and language settings can be toggled between English, Spanish, and French. A built-in fold-out stand makes tabletop placement simple, while a rear keyhole allows wall hanging.

• 2-inch digits for clear time viewing
• Crescendo alarm sound with 10-minute snooze
• Tabletop stand or wall-mount keyhole
• Language options: English, Spanish, French

What practical benefits does the moon phase display offer?

The integrated moon-phase icon provides a quick visual reference of the lunar cycle, useful for gardeners, anglers, photographers, or anyone who tracks moonlight. It’s a simple, non-technical indicator that complements the time and temperature information on the main screen. The moon graphic updates automatically alongside the clock’s date settings.

• Visual lunar cycle indicator for quick reference
• Updates with the atomic-set date for accuracy
• Useful for planning activities affected by moon phase
• Non-intrusive icon that doesn’t clutter the main readout

Who this is for: The La Crosse Technology 513-75624-INT is ideal for homeowners, office users, and hobbyists who want a low-maintenance, battery-operated clock that provides precise time plus outdoor temperature and moon information. Choose this unit if you prefer automatic time updates, an easy-to-read display, flexible mounting, and a simple way to check temperature trends and lunar phase without using multiple devices.
