Only if the exact watch’s rating and manual allow it. “Water-resistant” without a depth or BAR marking is not a safe basis for swimming: Timex says an unrated water-resistant watch should handle splashes and rain, but should not be submerged. Showering is a separate question; soap, shampoo, heat and water jets can create risks that a swimming rating may not cover. Check the case back and the manufacturer’s instructions for the specific model before wearing it in either setting.
What the water-resistance marking tells you
The retailer does not determine a watch’s water resistance. A convenience-store watch may have a useful rating, or it may be intended only for everyday splashes. The exact model and its condition matter; price and appearance are not substitutes for a rating.

Water-resistance figures are manufacturer activity categories, not a guarantee that a watch can be taken to that depth in every circumstance. Timex defines water resistance as “the ability to resist the penetration of water to a certain degree.” Its guidance says a watch marked water-resistant without a depth should not be submerged. Timex’s water-resistance ratings describe its own watches, not every brand sold at a particular retailer.
Can you swim with it?
Use the activity guidance for the watch’s own brand and model. The two manufacturers cited here describe their categories somewhat differently:
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.

| Marking or category | Manufacturer guidance |
|---|---|
| Water-resistant, no depth stated | Timex: splashes and rain, but do not submerge. Timex guidance. |
| 30 m | Timex lists handwashing. It does not list swimming for this category. Timex guidance. |
| 50 m | Timex lists handwashing and light swimming. Casio’s U.S. guide describes its 50 m category as suitable for swimming in shallow water. These are brand-specific recommendations. Timex; Casio America. |
| 100 m | Timex includes handwashing, light swimming, snorkeling, poolside diving and surfing. Casio’s U.S. guidance adds snorkeling and poolside diving to its 100 m category. Consult the relevant brand’s activity list. Timex; Casio America. |
| 200 m | Timex includes the activities listed for its 100 m category plus recreational scuba diving. This is Timex guidance, not a universal rule. Timex guidance. |
Casio’s module 5697 precautions offer a model-specific example: that manual lists a watch with no BAR marking for handwashing and rain, but not swimming; its 5 BAR row includes swimming. Apply those instructions only to the model covered by the manual. Casio module 5697 operating precautions.
Is swimming guidance enough for a shower?
No general shower-safe rule follows from a swimming rating. A shower can expose a watch to soap or shampoo, heat and directed water; the cited manufacturer guidance does not establish that any particular depth marking makes every watch safe to wear in the shower.

Casio advises avoiding baths and areas where soap or shampoo is used, and its module 5697 manual also cautions against hot or humid environments and tasks involving soap or detergents. Follow the exact model’s manual. If it does not explicitly permit showering, take the watch off. Casio’s U.S. water-resistance guidance; module 5697 precautions.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteHow to check an unfamiliar watch
- Read the case back for the exact brand, model and any depth or BAR marking. If there is no clear rating, do not assume it can be submerged.
- Find the official manual for that model and check the activities it explicitly allows. A general label is less useful than a model-specific activity list.
- Look for restrictions on bathing, soap, shampoo, hot water, wet buttons or operating the crown while wet. Casio warns against operating buttons or the crown while wet or submerged in its guidance.
- Consider the watch’s condition. A damaged case, opened case or unknown repair history makes an old water-resistance claim unreliable; the cited Casio precautions emphasize intact cases and gasket care.
If the marking is missing or the manual cannot be found, keep the watch out of the water until its instructions are verified.
