It is a pretty slow watch now.

If you only need it to tell time, then get a nice G-shock with 499.

If u want it to tell times and notification, but nothing more. Then u can consider....coz it can do nothing beside telling times and give u notification. I know because I am wearing one right now. The slowness is 

Just so you know generally, internet refer Apple Watch in:

Series 0 (the very first watch), series 1, 2, 3, and 4.

When u say series 2, I assume is the 3rd generation (not series 1 as mentioned above)
if yes, then the performance is more acceptable. If u comapre with series 0 and series 1. Again, why I know...my wife had a series 2, but she has upgraded to series 4.

I think seriees 2 is still acceptable la. For the price....hehehe

You can get series 3 new which is selling RM1099 in carousell. Sealed unit. Series 1 unit is too slow.
