Looking for a 5ATM smartwatch for swimming that can actually go in the water, not just survive a rain shower? Rugged smartwatch marketing throws around waterproof claims pretty loosely, and the rating that actually matters for swimming — 5ATM — only shows up on a couple of REXQU’s outdoor models. The rest are built for rain, mud and sweat, and nothing more.
Here’s the short version: if you want to swim with a smartwatch, look for both a suitable pressure rating and explicit manufacturer approval for swimming. A 5ATM label describes static pressure resistance; it is not a promise that every 5ATM watch is suitable for every water activity. Below is how REXQU’s swim-approved 5ATM models compare with IP68-only rugged watches, and what each rating actually tells you.
Why an IP68 Rugged Watch Still Isn’t a 5ATM Smartwatch for Swimming
IP68 and 5ATM measure different things, and mixing them up is the single most common mistake shoppers make. IP68 is an ingress protection rating that covers dust (the “6”) and water immersion under lab conditions (the “8”) — but that immersion test is usually static, shallow, and doesn’t account for the pressure and constant motion of swimming strokes. 5ATM is a pressure rating, meaning the case is sealed to withstand roughly 50 metres of static water pressure, which is the standard threshold watchmakers use for “safe to swim in.”
REXQU’s own TerraPulse is a good example of the distinction: it’s IP68-rated and genuinely tough against rain, sweat and spray, but the product FAQ is explicit that you should take it off for swimming and hot showers. Same goes for the BaseCamp — both are built for rain and splashes, not laps, and REXQU doesn’t pretend otherwise.
REXQU’s Actual 5ATM Smartwatch for Swimming Picks
Two models in the rugged lineup carry the real 5ATM rating: the REXQU Beacon Pro and the REXQU Ridgeline. Both are IPX8-rated to 5ATM, which their own FAQs confirm covers swimming, river crossings, rain and showers — with hot saunas and diving still off-limits, since neither is built for sustained high-pressure or high-temperature water.
The Beacon Pro runs a 525mAh battery for 5–7 days of daily use and 15+ days on standby, adds a flashlight with a 20+ metre beam plus UV and SOS light modes, and is priced at $149.97. The Ridgeline carries a smaller 400mAh cell rated for about 7 days of normal use and 15 days standby, in a reinforced 41.5×52mm case with a 1.8″ display and Bluetooth calling, also at $149.97. Both charge magnetically in around 2.5 hours and come with REXQU’s standard 90-day money-back guarantee.
| Model | Water Rating | Battery | Standout Feature | Price |
|---|---|---|---|---|
| REXQU Beacon Pro | IPX8 / 5ATM | 525mAh, 5–7 days | 20m+ flashlight, UV & SOS light | $149.97 |
| REXQU Ridgeline | IPX8 / 5ATM | 400mAh, ~7 days | 1.8″ display, Bluetooth calls | $149.97 |
| REXQU TerraPulse (not swim-rated) | IP68 only | 280mAh, up to 15 days | Multi-sport modes | $149.97 |
Who Actually Needs a 5ATM Smartwatch for Swimming?
If your routine includes pool laps, open-water swims, whitewater crossings on trail, or you just don’t want to think twice before diving into a lake on a hike, the extra assurance of a true 5ATM rating is worth it. Trail runners who ford streams and anglers who wade regularly fall into this camp too — the Beacon Pro’s stream-crossing durability is exactly the kind of everyday water exposure the rating is meant for.
If your water exposure is limited to rain, sweat and the occasional hand-wash, an IP68 rugged watch like the BaseCamp or TerraPulse will serve you fine and typically costs less. There’s no reason to pay for 5ATM protection you’ll never actually use.
Picking Between the Beacon Pro and the Ridgeline
Both are a legitimate 5ATM smartwatch for swimming at the same $149.97 price, so the decision comes down to what else you want on your wrist. Pick the Beacon Pro if a genuinely bright flashlight and longer standby battery matter for early-morning or overnight trips. Pick the Ridgeline if you’d rather take calls on your wrist and prefer its more compact 1.8″ case.

5ATM Swimming Smartwatch Checklist
- Check the product instructions: confirm that the manufacturer explicitly permits swimming rather than relying on the rating alone.
- Avoid hot water and steam: heat can affect seals differently from cool pool or open water.
- Rinse after salt or chlorinated water: fresh water helps remove residue around buttons, speaker openings and charging contacts.
- Dry before charging: moisture around magnetic contacts can interfere with charging and may accelerate corrosion.
- Do not press buttons underwater unless the manufacturer allows it: moving a button can momentarily stress a seal.
- Do not treat 5ATM as a 50-metre diving rating: the pressure test is not the same as real-world scuba use.

Frequently Asked Questions
Can I shower with a 5ATM-rated REXQU watch? Yes — normal showers are fine, but both the Beacon Pro and Ridgeline FAQs recommend avoiding hot saunas specifically, since heat and steam behave differently than cold water against the seals.
Can I dive with these watches? No. 5ATM covers swimming and surface water activity, not scuba diving, which needs a dedicated dive-rated device built for sustained depth pressure.
Is 5ATM better than IP68? They’re not directly comparable — 5ATM specifically certifies pressure resistance for swimming, while IP68 certifies dust and static immersion resistance. For swimming specifically, 5ATM is the rating to look for.
