Fossil Gen 4 Vs Samsung Gear Sport: Design and Display

Fossil always tries to make more stylish and durable smartwatches; that’s why these watches are popular among women. On the other hand, Samsung gives some sporty look to their wearables, making them best for athletes.
Fossil Gen 4
In the Fossil Gen series, all the watches follow the same design with minor changes that can be ignored.
Gen 4 must look like jewellery; you will get minute holes that entirely change its look on the bezels. These holes look like some diamonds, but in reality, these are holes.
Fossil Gen 4 comes with a Stainless Steel case that makes the watch much more durable. Compared to the latest Gen watches, Gen 4 is a pretty thick case that makes it bulky.
Like other Fossil smartwatches, Gen 4 has digital buttons on the right side that look like some knob. These buttons help you control the watch’s functionality, helps you in menu navigation, etc.
The best part is you can change the straps whenever you want, and Fossil offers a wide variety of straps for both men and women.
Fossil Gen 4 comes with a 1.77″ OLED display, which looks brighter than other fossil smartwatches. Because of the 454 x 454 pixels high resolution, you can easily view the dial under direct sunlight.
Unfortunately, Fossil watches are not as waterproof as Samsung wears, Gen 4 has a 3ATM of water rating, so it’s not suitable for deep pool swimming.
Samsung Gear Sport
Samson Gear Sport is my favorite sport watch with a robust design and sporty look. This watch has a unique design from Galaxy Watch Active 2, Watch 3, and 4.
In this sports watch, the dial is round, but the bezel is much like a square. The bezel is made up of stainless steel, which is undoubtedly a durable material.
Gear sport is a much comfortable watch. It has just 67g of weight (with straps), and the soft Silicon strap makes it a much more relaxing watch. Like other Galaxy smartwatches, there are two buttons in Gear sport that helps you to navigate through menus.
Compared to Fossil Gen 4, Gear Sport has excellent water-resistant capabilities; with a 50-meter water rating, you can wear this watch during swimming.
This watch has a 1.2″ AMOLED Always-on display with a rotating bezel in-display section. The display looks bright and vibrant, just like Galaxy Watch Active 2. The touch screen is smooth and sensitive, protected by Corning Gorilla Glass 3 protector.
Fossil Gen 4 Vs Samsung Gear Sport: Battery Life

In this comparison guide, the battery life section is very important as you will find some big differences here. Fossil always fails to give a solid battery performance, and this may be because of Wear OS as it drains more battery life.
On the other hand, watches on Tizen OS give much better battery performance. And for a sports watch, battery life is a very important factor. Not every outdoor watch can handle the battery consumption process, but Samsung has done a great job with it.
Fossil Gen 4 gives you an average battery life of one day, which is normal in Wear OS watches. But thanks to Fossil Gen 4 battery-saving modes that help you extend the battery life.
The Samsung Gear Sport comes with a 300 mAh battery that lasts for 3 days with typical usage and 5 days with low usage. So you can easily track your outdoor sports and fitness journey without the fear of fast battery consumption.
Fossil Gen 4 Vs Samsung Gear Sport: Price

Although the price section is not very important for some people, it’s most crucial for me. You can guess the number of features after checking price tags. And if a watch has a high price and low features, you should go for another brand.
You are well aware of the Fossil brand, as it has a strong background and long experience. That’s why Fossil smartwatches are expensive. And Galaxy watches have some decent price tags, and here you pay for what you get.
Fossil Gen 4 comes Fossil Gen 4 costs $279, which looks pretty expensive than Galaxy Watches. On the other hand, Samsung Gear Sport is available for $299, but I think the cost is fair as it offers many premium features.
