Water Resistance (IP67)
The ARMODD Silentwatch 4 Pro is IP67 waterproof, meaning it is protected from dust and can withstand immersion in water up to 1 meter for up to 30 minutes. It is suitable for daily use, such as washing hands or light rain exposure. It is not recommended for swimming, diving, or showering with hot water, as steam and high pressure can compromise the seal.
Strap Replacement
The 22-mm wide strap is replaceable. A silicone strap is included as a gift in the package. To replace the strap, locate the quick-release pins on the underside of the strap and gently slide them to detach the strap from the watch body. Attach the new strap by aligning the pins with the holes on the watch and releasing the pins into place.
