Wondering about daily health monitoring watch water resistance before you wear one in the shower or the pool? The ratings vary more than you’d expect across REXQU’s own lineup, and mixing them up is an easy way to damage a watch that looked identical to a swim-ready one on the shelf.
Here’s what the actual ratings mean on three real REXQU models, and which activities each one can and can’t survive.
Why Daily Health Monitoring Watch Water Resistance Ratings Differ So Much
Water resistance on a wearable is measured by an IP Code, an international standard that rates how well a sealed device holds up against dust and water under specific test conditions — not a guarantee of how it performs in real-world use like swimming laps or a hot shower. Two watches can both say “water resistant” on the box while one survives a downpour and the other doesn’t survive hand-washing.

REXQU VitaSync: IP67, Splashes and Rain Only
The REXQU VitaSync ($139.97) is rated IP67, which REXQU’s own product page spells out plainly: it covers sweat, rain and hand-washing, but not swimming, diving or hot showers. Water-resistance ratings describe a specific pressure test rather than an activity guarantee, so treat the IP67 rating as everyday splash protection for a watch that also tracks heart rate, blood oxygen and sleep around the clock with a 5–7 day battery.
REXQU HealthLink: IP68, the Highest of the Three
The REXQU HealthLink is rated IP68, one step above VitaSync on the same standard. REXQU lists it for everyday water exposure and recommends following the current care instructions rather than assuming any rating means unlimited exposure — a higher IP number generally means better sealing, but it’s still worth checking before deliberately submerging any wearable.
REXQU BioVision: IP65, the Most Limited
The REXQU BioVision ($149.97) sits at the other end at IP65, intended for sweat, rain and hand-washing splashes only. REXQU is explicit that BioVision should not be worn swimming, showering or submerged, and that water resistance can reduce over time as seals age — a detail worth remembering even for watches with a higher rating.
Comparing the Three Ratings
| VitaSync | HealthLink | BioVision | |
|---|---|---|---|
| Price | $139.97 | — | $149.97 |
| Rating | IP67 | IP68 | IP65 |
| Rain / sweat / hand-washing | Yes | Yes | Yes |
| Showering | No | Everyday exposure | No |
| Swimming | No | Not recommended | No |
None of these three REXQU daily health monitoring watches are marketed as dedicated swim trackers. If lap swimming is the point, look for a model specifically rated for it elsewhere in the REXQU range rather than assuming any daily health monitoring watch water resistance rating covers submersion.
How to Actually Protect Your Watch’s Rating
Ratings can decrease over the life of a watch as seals wear, so a few habits help regardless of which model you own: dry the case and band after sweat or rain, avoid pressing buttons underwater, and skip hot showers and pools even on the higher-rated HealthLink. When in doubt, check the current care instructions for your specific model rather than relying on the rating alone.
This is general product-care information, not medical advice — if you’re tracking a health condition, talk to your doctor about which monitoring approach and device fit your situation.
Frequently Asked Questions
Which REXQU model has the best water resistance for daily use?
Of these three, HealthLink’s IP68 rating is the highest and is listed for everyday water exposure, though REXQU still recommends following current care instructions rather than assuming unlimited protection.
Can I wear any of these in the shower?
Not recommended for any of the three. VitaSync and BioVision explicitly exclude showering, and HealthLink’s “everyday exposure” language stops short of guaranteeing shower or steam protection.
Does a higher IP number always mean more protection?
Generally yes for the water-resistance portion of the code, but the rating is a lab test result, not a promise about every real-world scenario — treat daily health monitoring watch water resistance numbers as a guide, not a guarantee.
