Running Watches

A running watch is a wristwatch designed to measure the elapsed time (lap time) of athletes at set distances during running or marathons. In recent years, the growing health consciousness has led to an increase in the number of people engaging in running.

With the rising popularity of running, a wide range of running watches has become available. Recently, models with built-in GPS functionality that can measure running distance, heart rate, and calories burned have become mainstream. However, simple products focused on time display and lap time measurement continue to enjoy strong popularity. By using a running watch, you can regularly measure your training data, allowing you to compare past and present data and feel your growth. Since you can set specific goals based on your training data, this not only improves physical fitness but also enhances motivation and helps relieve stress.

Smartwatches come with various additional functions beyond just telling time, but the differences from running watches lie in ease of use when measuring lap times and waterproof performance. Running watches tend to be more user-friendly for specific scenarios and generally offer higher waterproof ratings.

The features of running watches vary by model, but the main functions typically include:

The GPS function allows for accurate measurement of the distance run. By measuring the running distance, you can gauge your level and plan your training, gradually increasing the distance each day. Some running watch models also allow for recording the running route via GPS, enabling training that combines distance and route.

The lap time measurement function enables you to measure times for chosen intervals, such as every 1 km or 5 km. By measuring lap times, for example, if you are running at a pace of 7 minutes per kilometer, you can aim to improve your pace to 6 minutes and 30 seconds for the next run, helping with management and goal setting.

One of the most important aspects of running is to maintain a sustainable level of exertion. Therefore, it’s crucial not to overexert yourself while running. By checking your heart rate with a running watch during your run, you can engage in running that matches your exercise intensity. Gradually increasing your pace based on your heart rate can also lead to improved running records.

Many running watches can integrate data with smartphone apps. By transferring the data collected from the running watch to a smartphone app, you can accumulate historical training records, allowing you to track and manage your running data. Understanding how much you have improved based on past records can enhance your motivation for daily runs.

Some running watches come equipped with a solar charging system that allows for charging via sunlight. With solar charging capability, you can confidently use your running watch while running. Additionally, features like GPS distance measurement, lap measurement, and heart rate monitoring can consume battery power quickly. In such cases, the ability to charge via solar energy while running means you won’t have to worry about battery depletion.

Note: CASIO's Solar Charging System "Tough Solar" Tough Solar is Casio's unique solar charging system that combines solar panels capable of generating power even from fluorescent light with a large-capacity rechargeable battery. This system allows for efficient use of power-consuming functions such as measurement capabilities, radio reception, and lighting.

What are some tips for selecting a running watch?

Running watches range from those focused solely on lap time measurement to high-function models packed with various features. Since what each model can do varies, it’s important to confirm which features you need and which would be beneficial. For example, if you tend to run after work in the evenings, a model with auto-light or backlight features would make it easier to see the display at night.

When choosing a running watch, waterproof performance is a crucial point. It’s common for outdoor runners to encounter sudden rain or sweat that can wet the watch. By selecting a model with high waterproof performance, you can use it confidently in rainy conditions or environments with high moisture levels. For mild rain or sweating, a watch with everyday life waterproofing should suffice.

Compared to regular wristwatches, running watches are designed to be lightweight and fit comfortably on the wrist. A lightweight running watch is less likely to become a burden during exercise. Since arm movement is important while running, select a watch that is as light as possible and fits comfortably on your wrist.

High-function models with GPS functionality may consume battery power quickly, so choosing a model that supports both USB charging and solar charging will allow you to use distance and lap time measurement features with greater peace of mind.
