After a pretty impressive showing with the Apple Watch Series 5, what's left for Apple to improve on the next iteration, likely coming in 2020 under the name Apple Watch Series 6?

According to Apple analyst Ming-Chi Kuo (via MacRumors), one feature that's coming is improved water resistance, alongside overall faster performance and improved wireless transmission.

These improvements will come, Kuo claims, with the use of new LCP (liquid crystal polymer) material for the circuit board in the Watch Series 6. This is different from Series 5, which uses PI (polyimide).

The new model being speedier isn't exactly breaking news, but improved water resistance is interesting. According to Apple's specifications page, Apple Watch Series 5 has a water resistance rating of 50 meters (164 feet), and can be used for "shallow-water activities like swimming in a pool or ocean." It's not suitable for "scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth."

Kuo didn't share any additional details about the improved water resistance, but the logical next step for the Watch would be to get the kind of resistance that would allow for more extreme scenarios described above.

Apple Watch Series 5 was launched in September this year, and Kuo expects Apple to follow the pattern and launch the next iteration in the second half of 2020.
