XREXS 17 Inch Digital Wall Clock with Bluetooth auto-sync, auto-dimming and time/date/temperature display
Product description
At a glance
A 17-inch digital wall clock is a proper choice when you want time to be readable from across a room rather than squinting at a smaller display. The XREXS clock leans into that “visible at a glance” idea with very large digits, plus Bluetooth auto time sync so you’re not fiddling with it day after day.
It’s also not just a clock. On paper it combines time, date and temperature on the display, adds an alarm/timer mode, and uses auto-dimming to cope with different lighting conditions. That mix makes it feel aimed at everyday spaces where multiple people are coming and going—home offices, classrooms, gyms, and similar busy spots.
That said, it’s not perfect for everyone: if you strongly prefer battery-only operation or you’d rather not rely on Bluetooth pairing, it may feel a bit restrictive. And while the timer has a fairly practical range for routines, it’s still a wall-mounted digital clock—if you’re looking for something ultra-flexible like a fully featured smart display, you may find it a bit basic.
The essentials
The standout feature is the Bluetooth auto-sync timekeeping. You pair it once with your smartphone, and after that it’s designed to keep its time accurate without manual adjustments. For anyone who’s fed up with clocks slowly drifting (or being corrected only when someone notices), this is a genuinely useful approach.
Visually, the large 17-inch HD LED screen and extra-large digit sizing are meant to reduce the “where’s the time?” moment. The display also includes time/date and temperature, so you can check more than just the hour.
There’s also an auto-dimming system with a light sensor. In normal lighting it adjusts brightness for comfort and visibility. In complete darkness, you can turn the display off manually—handy if you’re placing it in a bedroom or a light-sensitive environment.
What you’ll notice day to day
In daily use, the clock’s size matters more than you’d think. In an office or gym area, big digits are what make the difference between “I can see it quickly” and “I’ll just check my phone”. With the 4.84-inch digits mentioned in the description, the whole point is readability from distance and different viewing angles.
The timer set-up is also likely to be more than a gimmick. The clock supports both countdown and count up, with a flexible timer range up to 29 hours, 59 minutes, and 59 seconds. When a countdown finishes, it includes an audible 90-second alert. That makes it well suited to cooking steps, workout intervals, beauty routines, teaching time management, or helping children understand how long something takes.
A small practical example: if you’re running a home workout, you can start a timed countdown for a set, glance at the wall clock when you’re between exercises, and keep your phone in your pocket. You get fewer interruptions and a clearer shared reference point.
Key takeaways
A solid reason to consider this clock is that it ticks several boxes at once: Bluetooth auto time sync, a large high-contrast LED display, auto-dimming, and multi-function controls (clock, alarm and timer). It’s the kind of “all-in-one” approach that can reduce the number of gadgets you need in shared spaces.
However, there are a couple of limitations worth weighing. It’s powered by an included outlet adapter, and the description also notes that battery-only/charging isn’t supported in the sense of powering and charging from elsewhere. That makes it less ideal if you need something you can place completely away from mains power. Also, because it uses Bluetooth auto-sync, you’ll want a smartphone available for the initial pairing and occasional setup.

Who it’s for
It suits you if you want a large, readable wall clock that’s designed for everyday practical use — especially in rooms where you’d rather everyone quickly see the time without crowding around a screen. It also makes sense for learning and training environments, or for households where routines benefit from visible timing.
It may not suit you if you prefer a clock that’s purely battery powered for placement freedom, or if you’d rather avoid Bluetooth pairing steps. If you want something that feels like a full smart home device with advanced connectivity, this stays firmly in the digital wall clock lane.
Final verdict
Should you buy it?
Buy it if the big-digit, wall-mounted readability matters to you, and if Bluetooth auto time sync would save you the usual hassle of setting or correcting the time. The auto-dimming and the manual display-off option for darkness are also strong “day-to-day” reasons to choose it, particularly for bedrooms, offices, and other spaces where lighting changes through the day.
Skip it if you need a fully independent battery-only setup, or if relying on Bluetooth for accuracy is a deal-breaker. It’s best viewed as a practical, multi-function digital clock for shared spaces—excellent when you value visibility and straightforward timing, but not the right move if you need maximum flexibility in placement or smart features beyond the basics.
Mini FAQ
Does it sync time automatically?
Yes. The description states it can automatically synchronise daily via Bluetooth after you pair it with your smartphone once.
Can the display be turned off at night?
The clock includes auto-dimming and can be turned off manually for complete darkness, which should help if light bothers you.
What does it show besides the time?
It displays time, date and temperature.
Is it battery powered only?
Not in the way you might expect: it uses an included outlet adapter, while the AAA batteries are there to preserve settings during power interruptions.
