Certainly easier to see than my old digital clock. Probably time for some new glasses too. ### ⭐⭐⭐⭐⭐ Review *by B***Y on 18 December 2025* Very easy setup & exactly as advertised. Easy to read ### ⭐⭐⭐⭐ Review *by N***1 on 2 June 2025* Decent clock. I was replacing my La Cross atomic clock that decided to die after many years. It was very similar to this except didn’t have the outdoor temp. BUT the outdoor sensor isn’t working with this unit anyway. We’ve even replaced the battery so I’ll probably return it. I feel like the clock is good. I wish the bottom was slightly larger as well as I have this hanging higher in the room. ## Frequently Bought Together - WallarGe Extra Large Atomic Clock with Indoor Outdoor Temperature, Ultra Clear 4.5'' Numbers Display with Auto DST, 4 Time Zones, Date and Day Display, Battery Operated - WallarGe Atomic Clock with Outdoor and Indoor Temperature - 12.5 Inch Self-Setting Digital Clock Large Display, Battery Operated Wall Clocks or Desk Clocks for Bedroom, Livingroom, Office - WallarGe Atomic Clock with Indoor Outdoor Temperature - Easy to Read - Self Setting, 14.5'' Jumbo Auto Set Digital Wall Clock Battery Operated --- ## 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.uk/products/717257872-wallarge-20-extra-large-atomic-clock-with-indoor-outdoor-temperature](https://www.desertcart.co.uk/products/717257872-wallarge-20-extra-large-atomic-clock-with-indoor-outdoor-temperature) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-23*
