With a technology that can augment our daily lives it is important to choose a smartwatch whose features integrate well with our lives.

First Look

这Casio Pro Trek WSD-F21HR智能手表is a sports watch through and through. This watch was designed with a more active and outdoorsy target market in mind. It’s integrated heart rate monitor that begins measuring your heart rate automatically if the watch detects motion.

这watch has a built in tool to measure oxygen consumption for your body per minute. It is rated at 5 bar WR meaning it can reach to 50 meters before suffering water ingress. The watch has a digital compass, altimeter, barometer, activity tracker and heart zone display. They are not trying to hide what kind of person this watch was designed for.

Software

这Pro Trek WSD-F21HR is running the ‘Wear OS’ by Google. The OS used to be named ‘Android Wear’ because it is running a version of the Android operating system designed specifically for smart watches. Because the watch is running an Android OS it can pair up with your phone and integrate with your android phones ‘Google Assistant’. This works with the built in microphone on the watch. This also means your phones notifications can show up on your watch which makes checking for quick updates a lot more convenient. Plus you don’t look like a phone addict if you are only glancing down at your watch. For all you iPhone users out there you might check out theIMCO Cowatch。

该手表还与GPS集成在一起，以在屏幕位置信息和创建路由的能力上提供。您可以通过语音命令找到指示并查看您的议程。应用程序集成非常有用，即使您过去没有考虑过对此类事情使用手表，您也会发现自己越来越多地依靠它，随着时间的流逝。

展示

显示器显然是数字的，对角度为1.32英寸，分辨率为320×300。它是带有颜色TFT LCD和单色LCD的双层显示器。自然，它是智能手表，它也是一个电容式触摸屏，具有反污染涂层。用更清晰的语言，这是一个非常清晰，明亮和清晰的显示器。当外出时，即使在充满阳光下，也没有难以查看屏幕上的消息或其他细节。

After getting the screen wet and just shaking it off the screen still had immediate response time. The screen also did not seem to have any noticeable changes in performance during durability testing on a dusty hike. The unique functionality in both the previous generation (Pro Trek WSD-F20）和WSD-F21是双层LCD和单色显示。

这watch is able to switch between the color LCD and the monochrome LCD as needed in order to minimize power consumption and maximize lifespan. In monochrome mode you are able to display the time and various measurements that consume the least amount of power. The display is also quite easy to read in monochrome mode while in full light.

When you want to get the full smartwatch experience you can throw it over to the color LCD and display vibrant color maps, sensor output, and notifications.

全球定位系统

这全球定位系统color map display has a few interesting features. Clearly with any GPS you are able to display your current position. The useful hiking feature is that you can also display your recorded movement on a color map. While hiking it is much more convenient to view your GPS information without pulling your phone and out risking an unfortunate accident. You are able to set a trail on your phones display and then track your completion of that trail right on the watch.

这Pro Trek WSD-F21also allows you to import GPS log data into the watch utilizing Google Drive. Another fun feature is showing routes you have already traveled and displaying markers you saved as checkpoints for interesting locations. An example of this is saving the location of some waterfall or hot spring or any interesting locations you find on your outdoor adventures.

设计

这Pro Trek WSD-F21has the classical diver and sport watch look. When you see the watch you know its meant to be a watch you wear while being physically active, and wearing the watch will indeed make you want to be physically active; If for nothing else than simply to make use of all the watches integrated features.

该表带有氨基甲酸酯带，以平衡灵活性和耐用性。它具有双针扣，旨在防止任何滑倒，并利用沿整个乐队发现的任何双孔调整适合度。这些孔的意思是多功能，使您可以更轻松地进行调整，同时增加透气性，以免粘在皮肤上。

You will find resin used in the bezel of the watch. Here they aimed to make the watch as light as possible. The weight of the WSD-F21 coming in at 81g which makes it the lightest watch in the Pro Trek series.

Durability

We mentioned before that the WSD-F21 is water resistant up to 50 meters though Casio specifically states that it should not be used for diving or snorkeling. The resin in the bezel is definitely strong enough to protect the display from most bumps you will find yourself encountering often on a strenuous climb or hike. The band being urethane won’t be easily broken.

As a smart watch you always want to be a little careful with the screen itself however. Though the watch will survive the normal wear and tear or bumps and scrapes you encounter on a normal hike, I wouldn’t recommend rubbing the screen up against any rocks directly.

尽管如此，您仍在寻找非常坚实的MIL-STD-810评级以达到耐用性。这是美国的军事标准，它测试了所有事物的各种环境因素，例如高压，温度冲击，雨水，湿度，沙子，灰尘，真菌，枪声振动以及一系列其他测试。因此，使用MIL-STD-810评级，您可以相当相信您的手表将在最简单的事情上生存。

特征

智能手表的特征是肉和土豆。Casio总结了手表功能为“知道您的状况，知道您的位置”。显然，条件方面都是与生物反馈有关的。前面提到的心率监测器是手表的重要特征，即表面链接到自动在运动时自动激活的心率测量功能。这种运动可以以步行，跑步，骑自行车的形式出现，或者手表检测到某种类型的健身房活动。仅在心脏数据上，您就会获得心率区域历史，每天最大和最小值，当然还有当前的心率。

Another really cool feature is the V02 max. This actually measures your maximum oxygen consumption for your body per minute per kilogram of body weight. The data is meant to be used as a guide for endurance training helping you estimate your max running times as an example.

Among those features you also have a display of the calories burned for the current activity. The goal ETA for whatever preprogrammed fitness goals you configured are also displayed on screen. With that you can also see the remaining distance to goal, the heart rate graph, the altitude change graph and speed graphs. Pretty much all the data you could use to measure your performance.

Moment Setter

这moment setter feature of the watch is an app that allows you to configure an alert based on timing you specify. Essentially this is just a glorified reminder app with some additional features like automatically informing you of a coming sunset while you are working in the tracking activity app.

这app could be configured to remind you to drink in a workout or let you know how long you have traveled when it detects that you have stopped moving forward. This app is Casio’s attempt to make your feedback a bit more automated but there isn’t much more going on with the app.

电池寿命

电池寿命在很大程度上取决于手表上各种应用程序和功能的使用。在“多时间模式”中，只有单色LCD Casio显示的时间和传感器数据才能宣传1个月的电池寿命。非常扎实，但是在这种模式下使用手表会使智能手表成为不太智能的手表。

通过正常使用智能手表功能，在颜色LCD模式下，您可以期待大约一半天的电池寿命。当您开始使用GPS或其他生物反馈，警报或手机上的媒体功能时，这自然会下降。考虑到您可以在节省电源单色显示屏和颜色显示器之间切换，您应该能够通过使用正确的活动模式来最大程度地发挥电池寿命。

最终判决

这Pro Trek WSD-F21is a very solid sports watch. It is not a watch you wear to a dinner date by any means but when you throw on your hiking boots and want to pit yourself against the outdoors, it will serve you well.
