Fossil Gen 3 vs 4 vs Gen 5: What’s the Difference?
Fossil Gen 3 vs 4 vs Gen 5: Display/Body
Going by the size, the newer Gen 5 Calyle has the smallest case size, this makes it a more compact watch compared to the other older generations, and off course is a better fit for people with smaller wrist size.
Although, the Gen 3 and 4 with wider display size will allow you see more at a glance compared to the Gen 5 with a slight smaller display size.
Fossil Gen 3 vs 4 vs Gen 5:Memory/Storage
The Gen 5 with 1GB RAM and Snapdragon 3100 chip under the hood has a much better performance than the Gen 3 and 4 with the 2100 chip and 0.5GB RAM.
Moreover, the Gen 5 also has 8GB onboard storage capacity which is twice what you get with the Gen 3 or 4. This will allow you take more of your favorite tracks with you.
Fossil Gen 3 vs 4 vs Gen 5:Media
The Gen 5 has microphone and loudspeaker, while the Gen 3 and 4 lack loudspeaker but have microphone. As a result, you can make and receive calls directly from the Gen 5 via Bluetooth calling which isn’t possible with the Gen 3 or 4.
Fossil Gen 3 vs 4 vs Gen 5:Battery Life
Although each of these three has a quite abysmal short battery life, the Gen 5 with the 3100 chip under the hood and featuring battery saver modes will last a bit longer than the other two.
Fossil Gen 3 vs 4 vs Gen 5: Which is Better?
The Gen 5 Calyle is clearly the best choice. It has a more distinguishing design, higher storage and memory capacity in addition to the more advanced 3100 chip which leaves it with a slight longer battery life and much faster performance.
