Closing this thread here after watching lots of reviews I come to conclusion.
Samsung Galaxy watch 4 LTE is having only three downside
1. Battery >> could be last 2 if we don't use LTE GPS etc
2. IOS compatibility >> I have another android phone to do setup mainly its for NFC Payment which I will do using hard reset
3. Customer service >> this is bad part based on luck what happen in future but is panthetic
I bought the galaxy watch 4 LTE at 14999 Actually 14700 INR using Magnus card and (GIFTR Voucher )
This will give me 4410 Edge points and I consider their value like this.
4410 x 0.8 = 3528 Vistra points + 30% bonus going on = 4586 CV points
NEW DELHI TO MUMBAI (Vistara cost ) 7K FOR 16 March
So this watch cost me 7700 INR
