Besides the three-hands movement (V175 quartz), the dial also features three chronograph subdials and one date window.

Focused on bringing the long-lasting beauty of the icy Arctic landscapes in the spotlight, this timepiece is more than just a gorgeous piece! The watch is designed in Denmark, which explains the effort to maintain a minimalist visual appearance with high-quality materials and features.
The IP-plated medical-grade (316L) stainless steel mesh bracelet and case, and the highly scratch-resistant and flat sapphire crystal lens combine nicely with the all-black visuals of the dial. The face is only disturbed by the white hour markers, black and white hands, and window date (3 o’clock position).
In the spirit of true minimalism, the main power source of its Japanese Quartz movement is light (provided by the sun or artificial sources).
In conclusion, this is a slim-looking timepiece that looks great on both men and women. It’s also only equipped with basic time features and its water resistance is minimal (50m or 164 feet).

In terms of design, this is a rather bulky watch with lots of buttons and plenty of information displayed at almost any time. Still, due to the titanium bracelet, it is not as heavy as you’d expect.

Elegant, reliable, and solar-powered, this timepiece can be the perfect solution for busy ladies. The visual impact is very pleasing due to the two-toned (silver & gold) stainless steel bracelet and case. In addition, the bezel features a golden tone and is set with diamonds.
The analog dial has a Mother Of Pearl background with a three-hand Japanese quartz movement and a date window in the three o’clock position. The hands and hour markers are golden, which affords the watch a sense of luxury.
The face of the watch and the mechanism inside are protected by a scratch-resistant Hardlex crystal lens which improves visibility. However, it’s important to note that this is not a watch with good water resistance. While it can withstand the occasional splashing, it may not recover if you take it swimming.

The resin strap is easy to clean and adjust (also waterproof), the plastic case is strong, and the side buttons are protected against water and dust. In addition, the crystal lens is scratch-resistant and doesn’t reflect the light, which makes it easy to read the watch in direct sunlight.
Set-up has a learning curve due to the multitude of features (dual countdown timers, stopwatch, World Time for 31 timezones and 48 cities, daylight savings, and 5 Alarms). You’ll also remark the rather clean face (two-hands movement, digital area, and battery status indicator) and the luminous indicators and hands.

Solar Watch Buying Guide
The power reserve of a solar watch represents its energy storage capacity. As you will see from the products we reviewed, some have a power reserve of up to 6 months to a year on a single charge.
This means that the built-in battery can store enough energy to keep the watch going for the estimated time period. In addition, some watches come with a second battery, in case the first one fails after several charging cycles.
Lastly, a good solar watch doesn’t need any battery replacements on its entire lifetime. According to recent tests, batteries continue to retain up to 80% of their power reserve even after 20 years!
Purpose of the Watch
The offer is extremely diverse when it comes to solar powered watches since almost any big watch brand has at least a few models. As such, you can get sports models, elegant designs, watches built around specific features, and so on.
In short, regardless of your needs, there is a solar powered watch for you out there!
Frequently Asked Questions
Keep the watch in direct sunlight (with the solar panel side up, if there is such a feature) for about three minutes. This will charge the battery for about 24h, so you can go on with your day until there’s more time for charging.
If you don’t have sunlight, it also helps to expose the watch to artificial light for about 3.5h. It will have a similar result as with sunlight but it’s more accessible to our modern lifestyle.
All solar watches come with a built-in solar cell to absorb sunlight and artificial light and turn it into electrical energy. The cell can be located on the dial or behind it, depending on the watch and its features.
As you can see from the reviews above, many solar watches can go for about 6 to 12 months on a single charge. For this to happen, the watch is fitted with a powerful battery that stores the energy produced by the solar cell. This way, the movement and other features will be powered and the user can go about his or her day without worrying about charging.
Solar powered watches can also be charged by exposure to artificial light (a lamp, a flashlight, or a regular lightbulb). But the charging process will be slower since artificial light doesn’t have the same intensity as sunlight.
So, to charge your watch without the Sun, place it on a table during the night (the side with the solar cells up) and leave the lights in that room open. It can also help if you place it directly under a powerful lamp, but make sure the heat it generates won’t affect the other elements of the watch (like the strap or the case).
Most producers say their watch can last for about 10 years, but with modern solar power technology, the watch never stops running. So, unless it suffers some sort of accident, there is no reason for your timepiece to stop.
Even more, contemporary models come with a built-in backup battery, in case the primary one fails after a number of charging cycles. However, the batteries used in solar powered watches can easily last a decade and more.
