Apple is known for making revolution with attention to detail. They analyse market and take time to release a better product may be a little late.
I brought it from US which costed me 7k less because of Black Friday sale.
I brought 42mm Space grey model.
Pros:
1) Accurate pedometer.
2) Beautiful watch faces.
3) Easy to connect(infact switch on the watch and it will connect if bluetooth is switched on, on the paired phone)
4) Build quality is top notch.
5) Watch os 3 makes it faster and more smooth.
Cons:
1) Battery drains faster on animated watch faces
2) Bands are very very costly
