La Crosse Technology Atomic Digital Clock — Gray frame with wireless outdoor sensor, calendar & forecast

The La Crosse Technology 512-85937 is a wall-mountable atomic digital clock that shows precise time, full calendar, indoor/outdoor temperatures with trend arrows, and a 12-hour forecast in a modern gray-and-silver design.

This streamlined digital clock combines automatic atomic timekeeping with a clear calendar and weather basics so you don't have to guess the day, temperature, or near-term conditions. The gray frame with a brushed-silver face fits both home and office settings, while the included wireless sensor reports outdoor temperature up to 330 feet away.

• Seven U.S. time zone settings (ATL to HAW) for regional accuracy
• 12- or 24-hour format to suit personal preference
