Queries on Seiko 5M23 6A10 AGS Tuna

Hi All,



So, I just got the above baby tuna, and I have the following queries :mrgreen: :



1. how do I get the manual for this?

2. the insert appears not to be the correct one. Where can I get a replacement insert for it and what are my aftermarket options?



Any help will be much appreciated.

TIA!
