We decided to try a new brand and zoomed in on a Marathon brand. So far, happy with functionality and features we were looking for: large numbers, indoor and outdoor temps, week days displaying etc. We're pleasantly surprised with the fact that, despite the overall size, all numbers are big enough in order to be seen from at least 7-8 feet. Will update in 6 months but, most likely, would recommend to others. Review: Functional, readable and excellent value for the price. - I was looking for a an atomic clock for my garage and this is perfect. Displays correct time and temperature and date automatically. Large letters easy to read and very clear. The package came with a separate transmitter for place outside to send temperture to the clock. Instructions very clear and setup took only minutes; it comes with batteries. I would definitely buy again and considering buying another for my home office. ## Features - HIGHLY LEGIBLE DISPLAY: Features large, easy to read 2" high display - SELF-SETTING/ADJUSTING: Using radio frequencies broadcast from NIST's Colorado Atomic Clock - 12 OR 24 HOUR: Choose to display the time in 12 or 24 hour format, also shows indoor/outdoor temperature display in Celsius or Fahrenheit - 8 TIME ZONES: Choose to display the time in 8 different time zones with option to turn Daylight Savings Time on or off - BATTERIES INCLUDED: Comes with 2 AA long life batteries ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B078NHLV3H | | Additional Features | projection clock, temperature display, atom, radio | | Alarm Clock | No | | Best Sellers Rank | #3,249,673 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #8,248 in Wall Clocks | | Brand | MARATHON | | Brand Name | MARATHON | | Clock Form | Mantel | | Color | Black | | Customer Reviews | 4.5 out of 5 stars 778 Reviews | | Dial Color | black | | Display Type | Digital | | Frame Material | Plastic | | Indoor Outdoor Usage | Indoor, Outdoor | | Item Dimensions W x H | 10.39"W x 11.96"H | | Item Weight | 1.3 pounds | | Manufacturer | Marathon | | Manufacturer Part Number | CL030027-FD-BK | | Material Type | Plastic | | Model Number | CL030027-FD-BK | | Mounting Type | Wall Mount | | Number of Batteries | 2 AA batteries required.

Displays correct time and temperature and date automatically. Large letters easy to read and very clear. The package came with a separate transmitter for place outside to send temperture to the clock. Instructions very clear and setup took only minutes; it comes with batteries.

Our old atomic clock finally broke after 20 years or more of having it. We ordered this one because it has a more modern look and the large display numbers really help when trying to catch a glimpse of the temp outside on your way out the door. Setup was easy, but we did have to let it sit overnight to let it sync up with NIST (not sure if right acronym). For those that like the temp, time and moon phase all at a glance, this clock is for you! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/57852434-marathon-cl030027-fd-bk-slim-atomic-wall-clock-with-full](https://www.desertcart.co.th/products/57852434-marathon-cl030027-fd-bk-slim-atomic-wall-clock-with-full) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-09-06*
