If you are looking for a waterproof screenless fitness tracker, the first thing to know is that “waterproof” is usually the wrong word. REXQU’s current screenless bands are rated 1ATM water resistant, which is designed for everyday exposure such as hand-washing, rain and sweaty workouts — not swimming, showering or prolonged submersion.
That applies across the current REXQU screenless lineup: PulseBand, CardioBand, AeroBand and GuardBand. All four are available through the static REXQU Screenless Fitness Trackers collection.
What Does 1ATM Mean on a Screenless Fitness Tracker?
ATM stands for atmospheres, a pressure-based way of describing water resistance. The important thing for buyers is not to treat the number as a literal promise that a wearable can be used at an equivalent depth in every real-world situation.
Water-resistance standards exist because laboratory test pressure, movement, temperature, soap, impact and ageing all affect how a watch behaves in real life. The International Organization for Standardization’s ISO 22810 water-resistance standard establishes test and marking requirements for water-resistant watches.
For REXQU’s 1ATM screenless bands, the practical guidance is simpler than the engineering: fine for hand-washing, rain and sweat; not recommended for swimming or showering.
REXQU 1ATM Screenless Fitness Trackers Compared
| Band | Water Rating | Battery | Stand-Out Feature | Price |
|---|---|---|---|---|
| PulseBand | 1ATM | 25–30 days typical use | On-band ECG + long battery | $139.97 |
| CardioBand | 1ATM | 7–10 days normal / 15–20 standby | ECG, HRV, cycle tracking | $139.97 |
| AeroBand | 1ATM | 11–30 days depending on use | Simple everyday tracking | $139.97 |
| GuardBand | 1ATM | 7–10 days normal / 15–20 standby | GPS, SOS, automatic fall detection | $139.97 |
Can You Wear a 1ATM Fitness Tracker in the Rain?
Yes. Rain is exactly the kind of brief everyday exposure the current REXQU product guidance allows. The same applies to sweat during a workout and normal hand-washing.
After heavy rain or a sweaty workout, wiping the band dry before charging is still good practice. Water on magnetic charging contacts can interfere with a reliable connection and may accelerate corrosion or residue buildup over time.
Can You Shower With a 1ATM Screenless Fitness Tracker?
REXQU does not recommend it. A shower is not just clean water touching the band for a moment. It combines sustained spray, heat, steam, soap, shampoo and repeated temperature changes.
Those conditions are different from a hand-washing splash or a run in the rain. If you want the band to last, remove it before showering and put it back on once you are dry.
Can You Swim With a 1ATM Fitness Tracker?
No — not with the current REXQU screenless range. PulseBand, CardioBand, AeroBand and GuardBand are not marketed as swimming trackers, and REXQU explicitly advises against swimming with the 1ATM bands.
If lap swimming or water workouts are part of your routine, the better strategy is to buy a wearable whose manufacturer explicitly approves swimming rather than trying to stretch a 1ATM rating beyond its intended use.
Why “1ATM = 10 Metres” Can Be Misleading
You may see 1ATM translated online into a theoretical water depth. That does not mean you should take a 1ATM band underwater to that depth. Pressure markings are based on test conditions, while real use adds motion, jets of water, changing temperatures, worn seals and other stresses.
This is why the manufacturer’s use guidance should take priority over a simple metres conversion. Casio’s explanation of watch water resistance, for example, also notes that pressure/depth markings should not be interpreted as straightforward permission to use a watch at that physical depth.
Which 1ATM REXQU Band Should You Choose?
Since water resistance is the same across the current screenless lineup, choose based on the features that matter after you step away from the sink:
- PulseBand: best when ECG and maximum battery life matter most.
- CardioBand: best for heart-first tracking, ECG, HRV and cycle features.
- AeroBand: best for simple, long-battery everyday tracking.
- GuardBand: best for GPS-oriented safety, one-press SOS and automatic fall detection.

Does Water Affect Heart-Rate or SpOâ‚‚ Readings?
Wet skin can interfere with the stable skin contact optical sensors need for consistent readings. Sweat, water droplets and a band moving around on damp skin can make a single measurement noisier.
For a spot check after exercise or washing, dry the skin and underside of the tracker first, then wear the band snugly and stay still. For more on wrist heart-rate consistency, see Screenless Fitness Tracker Heart Rate Accuracy Explained.
How to Protect a Water-Resistant Screenless Band
- Dry the band before charging. Never place wet charging contacts on the magnetic charger.
- Rinse or wipe away heavy sweat. Salt residue can build up over time.
- Avoid soap, shampoo and solvents on the tracker.
- Do not use the band in hot showers, saunas or steam rooms.
- Inspect the band after impacts. Damage can affect seals and fit.
- Follow the latest product-page guidance. Manufacturer instructions should override generic internet charts.
1ATM vs IP67 vs IP68
ATM and IP ratings are different systems, so they should not be compared as though one number directly converts to the other. IP ratings describe protection against solids and water ingress under specified tests, while ATM ratings are pressure-based watch markings.
If you specifically need a more water-resistant display-based watch, REXQU has IP67 and IP68 models elsewhere in its catalogue. But within the screenless fitness-tracker collection, 1ATM is the current standard.
Frequently Asked Questions
Are REXQU screenless fitness trackers waterproof?
They are water resistant rather than truly waterproof. The current PulseBand, CardioBand, AeroBand and GuardBand pages list 1ATM and recommend them for hand-washing, rain and sweaty workouts — not swimming or showering.
Can I wash dishes while wearing a 1ATM band?
Ordinary splashes are within the intended everyday use, but prolonged soaking, hot water and detergent exposure are best avoided.
What if I accidentally wear it in the shower?
Dry it thoroughly afterward and avoid charging until the band and contacts are completely dry. An accidental exposure is different from making shower use a regular habit.
Which REXQU screenless band is best around water?
All four current screenless models share the same 1ATM rating, so choose based on battery, ECG, heart tracking or safety features rather than water resistance.
Does 1ATM mean I can dive to 10 metres?
No. Do not interpret the pressure rating as permission to use the band at a literal underwater depth. Follow REXQU’s stated usage guidance.
The Bottom Line
A waterproof screenless fitness tracker search often leads to 1ATM bands, but the more accurate description is everyday water resistant. REXQU’s PulseBand, CardioBand, AeroBand and GuardBand can handle rain, sweat and hand-washing, but should come off before swimming or showering. Compare all REXQU screenless fitness trackers →
