allentian 9811 Luminous Watch Grey
The allentian 9811 is a lightweight digital watch built for daily wear and outdoor activities. Its 50.49 mm dial and 24 mm strap suit wrists that prefer a larger face. Students, runners and casual users gain core timekeeping tools in a single, ready-to-wear package. The CR2025 battery ships installed so the watch works straight from the bag.
Thermals noise and power draw
A CR2025 button cell powers every function without external charging or cables. The solid-state movement produces no audible noise and generates no perceptible heat during normal use. The sealed case keeps moisture out while the battery maintains steady voltage across the operating temperature range. Maintenance stays limited to a single cell swap when the display eventually dims.
WR50M waterproof rating
The WR50M rating covers splashes, rain, hand-washing and surface swimming but excludes diving or high-pressure water jets. Buttons must remain unpressed while the watch is wet to preserve the seal. Buyers who need deeper immersion or screw-down crown security should look for a higher ATM specification. For everyday wet-weather confidence the rating is sufficient.

Questions about this item
How do I install the CR2025 battery in the 9811 watch, and which step do people often get wrong?
Open the alloy bottom cover, insert the CR2025 button battery with the positive side facing up, then reseal the cover evenly to keep the WR50M waterproof rating intact.
What maintenance will the 9811 watch need later, and when?
Replace the CR2025 button battery when the display dims or functions stop; clean the PU plastic strap and plexiglass mirror with a damp cloth to maintain wear resistance.
What limit appears first on the 9811 during sustained water exposure?
The WR50M rating protects against splashes and brief immersion, but prolonged swimming or pressing buttons underwater will exceed the pressure limit first.
