Automatic vs Solar Watches: Understand the Differences and Choose Wisely

Various wristwatches are available to suit multiple tastes, lifestyles, and budgets. Automatic and solar watches are two of the most sought-after models among watch collectors and everyday consumers equally. Knowing the benefits of both types will allow you to make a more educated choice when shopping for a watch. This essay will compare and contrast the most important aspects of automatic and solar watches so you can choose which type is best for you.

Automatic watches

Automatic watches

Timepieces that get their strength from the motion of the wearer’s wrist are called automatic watches, but they also go by the names self-winding watches and mechanical watches. The watch is an elaborate mechanism that uses gears, springs, and other parts to maintain precise time.

A mainspring, a coiled spring that stores energy when wound, is the heart of an automatic timepiece. A semicircular rotary or oscillating weight winds the watch’s mainspring as the user moves their wrist throughout the day. The mainspring stores energy to turn the watch’s mechanisms and move the hands.

The power reserve of an automatic watch is how long it can keep running even if it isn’t being worn. When the watch’s mainspring runs out of power, the timepiece stops and can’t be used again until worn or manually reset.

Pros and Cons


  • Automatic watches are better for the environment and the wallet because they operate on the wearer’s motion rather than a battery.
  • Watch fans highly seek automatic watches due to their high level of craftsmanship and the complexity of their mechanical components and engineering.
  • Compared to quartz watches, automatic watches are less likely to experience timekeeping mistakes when exposed to magnetic fields of sufficient strength.


  • Due to the mechanical nature of the watch movement, automatic watches are less precise than quartz watches. Things like temperature fluctuations, wear and tear, and hard impacts can impact them. That may necessitate periodic schedule changes.
  • To guarantee the reliability and accuracy of their mechanical components, automatic watches need regular servicing and cleaning.
  • Automatic watches typically cost more than solar or battery-powered timepieces because of the superior engineering and handiwork that goes into making them.

Some Well-Known Brands of Automatic Watches

  1. The Rolex Submariner is a legendary luxury diving watch revered for its indestructible build, reliable mechanism, and classic style.
  2. The Omega Speedmaster is a world-famous stopwatch watch that made history as the first wristwatch to orbit Earth’s satellite.
  3. The Seiko 5 Sports is a line of reasonably priced automatic watches that has proven to be a favorite among newcomers to the world of wristwatch collecting due to its dependability, adaptability, and aesthetic appeal.

Solar watches

 Solar watches

Solar watches are wristwatches that are powered by light generated by photovoltaic cells. The solar cells, which can be found on the dial or face of the watch, can collect energy from natural and manufactured light.

A refillable battery or capacitor within the timepiece stores the electrical energy produced by the solar cells. This power supply is used to power the watch’s quartz mechanism. The quartz movement operates based on a tiny fragment of quartz crystal that, when subjected to an electric current. The vibrations are transferred to the digits of the watch, allowing for precise timekeeping.

Pros and Cons


Solar watches utilize renewable energy sources, making them an environmentally friendly option compared to traditional battery-powered watches.

Solar watches do not require regular battery changes or manual winding. As long as they are exposed to light, they will continue functioning, reducing the need for frequent maintenance.

Solar watches use quartz movements, known for their accuracy, making them more precise than mechanical watches, including automatic watches.


  • Solar watches can be sensitive to extreme temperature fluctuations, which may impact the performance of the solar cells and the watch’s accuracy.
  • Solar watches have a limited power reserve when not exposed to light for extended periods, which can cause the watch to stop functioning if not recharged regularly.
  • Although solar watches generally require less maintenance than automatic watches, they may still need occasional servicing if the solar cells or rechargeable batteries degrade.

Examples of Popular Solar Watches

Citizen Eco-Drive: Citizen’s Eco-Drive series is a famous line of solar-powered watches known for their innovative technology, stylish designs, and reliable performance. The Eco-Drive technology allows the watch to run continuously, with some models having a power reserve of up to several months.

Seiko Solar: Seiko’s solar watch collection features a variety of models, from elegant dress watches to rugged sports watches, all powered by Seiko’s solar technology. Seiko Solar watches are known for their efficiency, durability, and affordability.

Casio G-Shock Solar: Casio’s G-Shock Solar watches combine the legendary toughness and durability of G-Shock watches with solar-powered technology. These watches are designed for outdoor enthusiasts and those who need a rugged, reliable timepiece that can withstand harsh conditions while remaining eco-friendly.

Comparison between Automatic and Solar Watches

The main differences between automatic and solar watches are their power source, accuracy, maintenance, and price.

Power source:

Automatic watches rely on the wearer’s movement to generate power, while solar watches harness light energy to power their batteries.


Solar watches use quartz movement and are generally more accurate than automatic watches, which may require regular time adjustments.


Automatic watches need regular servicing and winding. while solar watches have lower maintenance requirements, only needing occasional servicing if the solar cells or rechargeable batteries degrade.


Automatic watches are typically more expensive due to their intricate mechanical components, while solar watches are often more affordable.

Different scenarios:

Automatic watches are ideal for those who appreciate a mechanical timepiece’s fine craftsmanship and prestige. Solar watches are better suited for those seeking an eco-friendly, low-maintenance, and accurate daily wear, sports, or fashion clock.


In summary, both automatic and solar watches offer unique advantages, and the best choice ultimately depends on personal preferences and needs. If you value mechanical artistry and the heritage of traditional watchmaking, an automatic watch may be a perfect choice.

On the other hand, if you prioritize sustainability, low maintenance, and accuracy, a solar look would be an ideal option. By understanding the differences between these two types of watches and carefully considering your lifestyle, preferences, and requirements.
