YIJDACASE 2-Pack Waterproof Apple Watch Case, 40mm with 9H Glass
Product description
If you want everyday protection for a 40mm Apple Watch, this two-pack combines a case and screen cover in one accessory. Its polycarbonate bumper surrounds the watch, while built-in 9H tempered glass covers the display. The sealed design is made for contact with water, sweat, dust, and moisture. Matte black gives both cases a consistent, understated look.
Where it shines

The integrated case and screen protector offer a convenient alternative to choosing and fitting a separate bumper and display cover. This design is intended for Apple Watch SE 3, SE 2, SE, and Series 6, 5, and 4 in the 40mm size. Check the marking on the back of the watch to identify its size before choosing the case.


For routines that involve handwashing, rain, or a workout, the built-in seal ring and screen cover are designed to help keep water from entering the display area. The cover is also described as sweatproof, dustproof, moisture-proof, and anti-fog, making it suited to everyday wear where the watch may encounter more than dry indoor conditions. The polycarbonate bumper helps guard against scratches and bumps, while the tempered-glass surface adds a protective layer over the screen.

Key points
The 2-in-1 construction keeps the bumper and display cover together, so there is no separate screen protector to align after putting on the case. The 9H tempered glass is designed to resist scratches while remaining touch-sensitive, allowing you to use the covered display. A matte screen surface and fingerprint-resistant finish help keep the front looking neat through regular handling.



Precision cutouts provide access to the watch’s rotary control, buttons, and charging port. The case is described as ultra-thin and lightweight for comfortable wear, and its openings are designed to keep regular controls and charging accessible. You receive two black cases, which is useful if you want a spare or prefer to keep another cover available for a second watch in the same compatible size.
How to take care of it

Before installation, remove dust and dirt from the watch surface with a cleaning kit. Then place the cover over the watch, installation requires no tools. Taking this preparation step helps keep debris from being trapped between the display and the built-in glass. The case is designed to stay on while you use the watch’s controls and connect the charging port.


Practical questions

Will this case fit my Apple Watch? It is made for the 40mm Apple Watch SE 3, SE 2, SE, and Series 6, Series 5, or Series 4. Check the watch’s back for the 40mm marking before selecting it.
Can I use the touchscreen with the cover on? Yes. The built-in tempered-glass protector is described as touch-sensitive, and the case has cutouts for the rotary control and buttons.

What comes in the pack? The product is a two-pack of black cases, each combining a polycarbonate bumper with a built-in tempered-glass screen protector.
Buying verdict
For owners of a compatible 40mm Apple Watch who want both bumper coverage and a built-in screen protector, this YIJDACASE set brings those functions together in a straightforward, tool-free fit. Its water-focused design, accessible controls, and two-case pack make it a practical choice for daily wear that includes workouts, handwashing, and time outdoors.
