If you’re weighing flashlight smartwatch water resistance ratings before you buy, the number stamped on the case back actually matters more than the lumens on the box. A wrist light is only useful if it survives the rain, the dog walk, or the accidental dunk in the sink — and REXQU’s four flashlight watches don’t all carry the same rating.
Here’s a straight comparison of what each model can handle, so you can match the watch to how you’ll actually use it.

Flashlight Smartwatch Water Resistance, Model by Model
| Model | Rating | Best Interpreted As | Price |
|---|---|---|---|
| REXQU Beacon Pro | 5ATM | Suitable for surface swimming where the product instructions permit; avoid diving, hot water and high-pressure jets | $149.97 |
| REXQU Ridgeline | 5ATM | Suitable for surface swimming where the product instructions permit; avoid diving, hot water and high-pressure jets | $149.97 |
| REXQU EnduroBeam | 3ATM | Rain, sweat and splashes; not a swimming rating | $159.97 |
| REXQU Prisma | IP67 | Dust protection plus controlled temporary immersion testing; REXQU advises removing it for swimming and showers | $129.97 |
What 5ATM vs 3ATM vs IP67 Actually Cover
ATM and IP ratings answer different questions. An ATM rating is a pressure-resistance test; an IP rating describes protection against solids and water ingress under defined test conditions. A 5ATM watch is pressure-tested to 5 atmospheres, but that does not mean you should literally take it 50 metres underwater. For REXQU’s flashlight lineup, treat Beacon Pro and Ridgeline as the surface-swimming choices where the product instructions allow it; keep 3ATM EnduroBeam out of the pool; and follow REXQU’s own guidance to remove the IP67 Prisma for swimming and showers.
If swimming is the deciding factor rather than the flashlight itself, see the dedicated 5ATM smartwatch for swimming comparison. For a broader purchase decision, the flashlight smartwatch buying guide compares water resistance alongside beam type, battery life and everyday use.
Why Flashlight Smartwatch Water Resistance Matters More Than Beam Brightness
A flashlight watch usually gets reached for in exactly the conditions where water resistance is tested: the midnight dog walk in the rain, the fuse box in a damp basement, the tent flap during a storm. A bright beam is wasted if the watch behind it can’t take a splash. That’s the real reason flashlight smartwatch water resistance deserves more attention than the marketing copy usually gives it — beam power gets top billing, but the rating decides whether the watch survives the situations that made you want a flashlight on your wrist in the first place.
Which Rating Fits Your Use Case
- Swimmers and pool owners: the 5ATM Beacon Pro or Ridgeline — both also add UV light modes alongside the flashlight.
- Trail runners and hikers caught in weather: any of the four will handle rain, but 5ATM gives the widest safety margin.
- Everyday, office-to-errands wear: the featherlight, 30-gram Prisma at IP67 covers hand-washing and rain without asking you to think about it.
- Long-battery outdoor use: the EnduroBeam‘s 3ATM rating plus its 25–35 day battery suits dry-to-damp conditions over a long trip, just not full submersion.
All four watches also track heart rate and sleep around the clock, work with both iPhone and Android through REXQU’s free companion app, and carry no subscription. Browse the full flashlight smartwatch collection to compare beam type, battery life and price side by side.
Keeping Any Rating Working Over Time
Water resistance on any smartwatch fades a little with age — seals compress, charging ports collect grit, and a hard knock can crack a gasket without leaving a visible mark. A few habits keep the rating closer to its day-one number for longer: rinse the case in fresh water after a swim or a sweaty hike (salt and chlorine are harder on seals than plain rain), dry the charging contacts fully before connecting the magnetic charger, and avoid pressing buttons underwater since that’s when a small design tolerance is most likely to let water in. None of REXQU’s flashlight watches are rated for hot showers, saunas, or high-pressure washing, even the 5ATM models — heat and pressure both stress seals in ways a swim doesn’t.
Flashlight Smartwatch Water Resistance FAQ
Can I swim with a flashlight smartwatch? Only the 5ATM-rated Beacon Pro and Ridgeline are rated for swimming. The 3ATM EnduroBeam and IP67 Prisma handle rain and splashes but shouldn’t be submerged.
Is IP67 as good as 5ATM? They measure different things — IP67 confirms dust resistance plus brief shallow submersion, while 5ATM is a pressure-based test more representative of swimming and showering. For a swim-ready watch, look for the ATM rating specifically.
REXQU watches are wellness devices, not dive computers — none of the four are rated for scuba, water sports, or high-pressure water jets, regardless of ATM rating.
