Yes, the Citizen Terra Force AW1766-51E has a water resistance of 100 metres. This rating makes it suitable for daily wear, including showering, swimming, and snorkelling, but it is not recommended for scuba diving.
What type of movement powers the Citizen Terra Force AW1766-51E?
This Citizen Terra Force watch is powered by an Eco-Drive solar movement. This innovative technology converts any light source into energy, storing it in a power cell, which means you never need to replace a battery.
How does the Terra Force compare to other watches in its price range?
The Citizen Terra Force AW1766-51E stands out with its Eco-Drive solar technology, offering maintenance-free operation compared to many battery-powered alternatives. Its 100m water resistance and durable stainless steel construction provide excellent value for a versatile tool watch.
Is the mineral crystal on this watch durable enough for active use?
The mineral crystal on the Citizen Terra Force AW1766-51E offers good resistance against impacts and shattering, making it suitable for most active daily use. However, it can be more susceptible to scratches than sapphire crystals found on higher-end watches.

Editor's take
The Citizen Terra Force AW1766-51E emerges as a compelling option for individuals seeking a robust and environmentally conscious timepiece. This model, part of Citizen's commitment to accessible innovation, offers a blend of utilitarian design and modern aesthetics, making it a versatile choice for daily wear and light adventure. It caters to those who appreciate a watch that is both functional and effortlessly stylish.
Central to the Terra Force's appeal is its Eco-Drive solar movement, a hallmark of Citizen's engineering prowess that harnesses any light source to power the watch, negating the need for battery replacements. Encased in a substantial 43mm stainless steel case and protected by a durable mineral crystal, the watch is built to withstand the rigours of everyday life. Its 100-metre water resistance further enhances its practicality, allowing for worry-free use during swimming and snorkelling.
While the mineral crystal offers good shatter resistance, it is more prone to scratches compared to sapphire, which might be a consideration for those in highly demanding environments. The absence of a screw-down crown, despite the 100m water resistance, suggests it's more suited for surface water activities rather than serious diving. Furthermore, the minimalist dial, while clean, lacks the intricate details some enthusiasts might seek in a dedicated tool watch.
Ultimately, the Citizen Terra Force AW1766-51E is an excellent choice for the eco-conscious consumer who desires a reliable, low-maintenance watch with a strong, modern presence. It serves as a solid alternative to entry-level quartz watches, offering superior technology and a more refined aesthetic for its price point. Consider this model if you prioritise sustainability and everyday durability.
