I am using Sonata watch since last 3 years and found no errors or any mistakes. This is a brand for all those who are willing to wear branded stuff but dont have enough money to buy major and costly brands.
Its a brand mostly used by every age group either students or aged person. This is completely value for money.
Design of watch is extremely good. Look is awesome. They have various range starts from lower to higher, Sonata has various options like strip or chain or analog or digital.
If you are planning to buy a watch in low range but with a brand name then you can go for this brand. It;s full value for money and with 1 year warranty.
