Seiko has been successfully release many Monster limited editions for Thailand market. The variations between each edition are mainly dial color and number of productions. The prices for these limited watches were originally around THB 20,000 (~USD 650) but when they hit the secondary market the price went up much higher. For example the Yellow Monster's price is now about THB 70,000 (~USD 2300) as the production number is very low at 300 pieces.
Seiko Snow Monster is the latest monster limited edition which is the 8th model of this limited series. The number of productions is 2555 pieces. There is a rumor that the watches were sold out in lees than half an hour!!.
