i dont think sinn will help you pvd and tegiment a st steel case of its watch!
unless you order a 100 pieces from them.... they customize it for you!
or else, then every1 will buy a sinn u1 n then send it pvd to get a sinn u black!
no other watch brand will do that as well!
u can send your sinn watch case to other ppl for pvd...
but pvd without tegiment is not a sinn! then better buy a pvd sinn watch!
