Dear Oliver,
last year I bought also a Seiko like yours from Amazon for < 150€ for holidays. The first one I sent back because I was of the opinion the winding system was broken. But shame on me, I didn't realize that I have to shake the watch for winding. A fellow forum user called this watch a "Shaking Seiko"
After wearing this watch for almost 4 weeks I was surprised by comfort and accuracy of this watch. Great value for money and in the meantime I wear this one also at normal days not only at holidays.
For me this watch is a perfect entry to the world of mechanical watches.
