Tips for Maintenance and Recharging of a Sundial

What kind of maintenance does a sundial require? If there are still doubts, the good news is that they don’t need much. Of course, there are some points to consider in this regard, such as: changing the rubber seal of water-resistant watches every two or three years so that its resistance remains effective.

Also, it is necessary to prevent damage caused by extreme temperature changes. If that is not taken into account, the performance of the watch will suffer. Concerning the strap, it all comes down to the type of material it was made from because each one needs a different cleaning method. The most common types of straps are:

  • Leather – Wipe off sweat and moisture with a towel as soon as possible.
  • Metal – To avoid rust and corrosion, clean with a towel using neutral detergent and water.
  • Polyurethane – It can be cleaned with ordinary water without any problem.

How to recharge the solar battery quickly?

The first thing to note is that solar-charged watch owners who repeatedly go outside and have direct contact with sunlight, probably don’t need to wear anything else. In case you do not know the exact life of the battery, several models provide an indicator and the rest would be to charge it quickly.

It is also good to be in an optimal place where sunlight is available, such as near a window. On the other hand, in warmer climates, it can take up to 30 hours for the solar-charged watch to fully charge. In case the temperature is cold, it can take twice as long.

What to do if you live in a place where there is hardly any sun?

If you live in a place where sunlight is not so present, such as in Nordic countries where the days are very short in hell, it is best to buy a solar watch that is capable of charging its battery with artificial light. This type of light is generated utilizing electricity (halogen lamps, fluorescent lights, light bulbs, LEDs, etc.)

When an optimal light source is available, the watch should be 20 inches away for recharging. It should also be mentioned that it is not as efficient a method compared to natural sunlight since, if you want to fully charge the watch with artificial light, it can take up to 150 hours, that is, several whole days.

How do sundials work?

In the same way as other devices, some smartwatches work by being “powered” by solar energy thanks to a solar cell also known as a photovoltaic cell. These cells do their job by converting sunlight or solar radiation into energy and then converting it into electricity, which is used to supply watch batteries.

The solar panel is normally located on the back of the glass and the sphere can be located on the top of the solar panel, in some cases, it is also directly on the solar panel. Likewise, photovoltaic cells have progressively evolved by improving their capacity and resistance since they first came out in the 1970s.

There is not much difference compared to a traditional watch, the interesting thing is in the ability to save energy. Like any other conventional watch, it shows the time and, depending on the type of make/model, it has other peculiarities such as for example, alarms, stopwatches, timers, or even smarter functions, etc. Finally, sundials can be analog and digital, even hybrids.

Solar-charged Watches Buying Guide [Year]

Strap Type

When deciding to choose a good sundial or any other type, the first thing to consider is that it is an object that will be on the wrist most of the time. A watch with a stainless steel strap could be a great alternative to dressing both formally and casually. Likewise, the option of going traditional and using a leather strap is still good, although more resistant straps made of textile materials or silicone are very fashionable lately.


The next most important thing is to ask yourself “For what purpose is my sundial?” If you intend to wear a watch wearing formal clothes, it means that it will have a minimum use in energy and duration. If it is intended to be used for athletic activities or hiking, it is appropriate to find one that will withstand the periodic load that the user gives it. For both cases, there will always be exceptions.

On the other hand, for those looking to dive into the water, the G-Shock Frogman watch is appropriate to withstand the pressure of up to 650 meters deep. There are also devices for taking long walks because they have altimeters, as is the case with the Tissot T-touch.

Alternative Charging method

Of course, the attraction of a solar-charged watch is that it works with the sun’s energy. However, some models also have their traditional charging mode, an option to consider if you live in areas where there is not much sunlight. Having a hybrid watch will ensure greater security, which is why it is good to consider.

Without further ado, below we leave you with a list of the best sundials that can be found currently for sale. Obviously, we have tried to cover different price ranges to meet the needs and budgets of all users. We’ve even added a solar-charged hybrid smartwatch that more than one person is sure to like.
