globally SEIKO is the most popular brand , being the oldest ,
casio is also very popular name all over especially it G- shock series ,
invicta though a very good brand , is not so popular globally mainly because of its limited availability
in short seiko and casio are established names and even a noob in watches wud have heard of the same names over n over again ,
whereas only a few people interested in watch brands may know that even a brand called invita exists ,
and if u r getting a watch just to show off that its bought from phoren land , then u can even buy a seiko and still say that coz its hard to find good seiko watches in India
most of the imported brands are available in india in the grey market atleast- read smuggled
invicta may be passed off as a cheap chinese brand by some of ur friends
the choice is yours

its a singapore based website, vry reliabe , they do ship to india as well , free registered parcel or 20$ EMS- express mail service , ,
i had a talk with their online sales person as well - Mr Jason regarding shipping to india and custom clearance ,
he told me that they usually undervalue the parcel so as to avoid any customs , but if at all they have to charge custom duty , it wud be anywhere in the range of 500-1000 Rs for 100-150$ watch
