[Seiko] Just unboxed my first Seiko and it’s love at first sight!

So for last year or so I really started getting into watches and ofcourse was looking to buy my first Seiko automatic. Somehow after months of visiting shops and online websites, my needle finally got stuck at the Seiko 5 SRPE57K1. The smooth Bezel, the two tone hands go together very well. And then ofcourse the japanese day was a nice touch and ode to the Japanese maker . I didnt know it had that so was a pleasent surprise. Pretty happy with it, cant wait to wear it out.

Any suggestions on alternative watch straps that i could go for? NATO or Leather? Colours too if you will.
