Seiko

Hi guys, I have recently purchased a Seiko 45899. This is the first chronograph by Seiko, produced for the 1964 Tokyo Olympics. I was wondering if anyone would know which bracelet I can match with this watch? Thank you Jarrod ...  

I'm quite sure it is 18mm. I will have a look at the beads of rice.

Size? please Vte

It's an amazing piece and am very excited to receive it soon!

Enjoy it. Vte
