go and read some dealer reviews - there are PLENTY
I have never bought from Puretime (but have from PreciousTime - dont get them confused, as it is easy to do when people say PT), but have read a few bad things
perfect clones and trusty are fine - not the cheapest, but fine
watcheden has so much junk mixed in with the good stuff, its ridiculous!
silix is good, hont is good, 7750 is good - heck, there are so many good dealers - just read the dealer reviews. everyone has their own favourite dealer(s)
