There is a huge amount of misunderstanding and misinformation on the web around these straps stating that they are one particular style with uniform quality. This is simply not true. They are made in different locations in different countries including, but not exclusively, Malaysia, Singapore, Japan and China. Each is slightly different in appearance and quality. Our straps are often removed from genuine Seiko watches which are modded (with a steel mesh strap).
