OCEST 18 Inch Outdoor Clock — Waterproof Wall Clock with Night Light, Thermometer & Hygrometer

The OCEST 18-inch outdoor clock is a weatherproof wall clock that shows time, temperature, and humidity and includes an automatic night light for easy reading after dark.

This oversized 18" clock combines a large, easy-to-read dial with integrated temperature and humidity gauges so you can monitor conditions at a glance. Built with a sealed rubber gasket and durable materials, it resists rain and moisture while the silent quartz movement keeps time without distracting ticks. The built-in light sensor switches a soft LED night light on in low light and off during daylight, with selectable brightness levels and auto shut-off to conserve batteries.

How does the automatic night light work on the OCEST clock?

The clock has a built-in photosensor that detects ambient light and activates the LED night light only when it’s dark. You can choose Off, Low, or High brightness modes, and the low/high settings include an auto shut-off after up to five hours to extend battery life.

• Three night modes: Off (O), Low (I), High (II)
• Light sensor turns LEDs on in darkness and off in bright conditions
• Low/High modes run up to five hours with automatic power cut
• Battery-powered night light—no external wiring required

Is this clock built to withstand outdoor weather and moisture?

The case uses a sealed rubber gasket around the movement to block rain and humidity, making it suitable for covered patios, porches, poolside walls, and garden spaces. Materials and assembly prioritize water resistance rather than complete submersion, so avoid placing the clock where it will be fully submerged.

• Sealed rubber gasket protects internal quartz movement
• Durable, weather-resistant casing for wet and humid areas
• Recommended for protected outdoor locations, garages, and greenhouses
• Not intended for continuous underwater use

What environmental data does the clock display and how accurate is it?

The dial integrates analog temperature and humidity readouts alongside the clock face, offering an immediate picture of current conditions. Temperature range covers -40°F to 140°F (-40°C to 60°C) and the hygrometer displays 0–100% relative humidity—suitable for general outdoor monitoring.

• Temperature range: -40°F to 140°F (-40°C to 60°C)
• Humidity range: 0–100% RH for broad condition tracking
• Analog gauges give quick visual reference rather than lab-grade precision
• Ideal for gardening decisions, poolside comfort checks, and general awareness

How is the OCEST clock powered and maintained?

The timekeeping mechanism runs quietly on a single AA battery, while the night light uses four D batteries; there are no cords to hide or install. The silent quartz movement ensures noise-free operation and occasional battery replacement is the only routine maintenance.

• Clock: 1 x AA battery (not included)
• Night light: 4 x D batteries (not included) for extended run times
• Ultra-quiet, non-ticking quartz mechanism for bedrooms or quiet outdoor spaces
• Wipe clean the exterior and check gasket occasionally for debris

Who this is for: This OCEST 18" waterproof outdoor clock is designed for homeowners and outdoor hosts who want one clear display that combines time, temperature, and humidity with an automatic night light. It suits people outfitting patios, pool areas, greenhouses, garages, and covered outdoor living spaces who need a reliable, low-maintenance clock that withstands damp conditions and remains easy to read day or night. It’s also a practical decorative gift for housewarmings and outdoor-living upgrades.
