Modded Seiko's
Discussion
I have put together a fair few based around the NH movements. However, other than the movement, nothing else is Seiko. Only Seiko I have modded is this one (now sold due to lack of wear):
After market hands (kindly sold to me from someone on this forum)
Sapphire Crystal
Rubber Strap
I also swapped out the shake to wind movement to the hand winding NH36.

Both good looking watches.

This terrible picture shows my custom Seiko.
It’s an SKX-009 so has the very slightly blue strap and face.
I selected the upgrades, bought most direct and Zander at Jarrott Watches put it together (and swapped some wrong parts I’d bought).
It has:
- Knurled bezel and crown.
- Dark Knight bezel insert.
- upgrade movement (I forget which).
- a slimmer case back.
- the hands are unique, at least in combination - pink for my partner, purple for my son and orange for me.
I’ve barely taken it off.
