As per many reader request, today i would like to do a hands-on DIY SKX to NH36 upgrade tutorial. (thanks to Brian Gregg for the project).
Its has been discussed in the below 2 articles, but some reader still finds it confusing on the DIY mod. Therefore, this article is a tutorial and probably a summary/merging both the articles below.
Triple charge your Seiko SKX007 with Dragon Shroud, Jumbo crown and a NH36 !
Supercharge your SKX007 with a NH35/36
You will needs the following :
a) Seiko SKX watch
b) NH36 (DAY/DATE) movement – https://seikoparts.wordpress.com/2016/05/05/for-sale-sii-nh35-4r35-automatic-movement/
C) SKX aftermarket crown (Jumbo crown in this case – https://www.dragonshroud.com/product-page/jumbo-tuna-crown-for-7002-skx007-skx009-011-a5 )
D) NH36 pre-cut stem – https://seikoparts.wordpress.com/2015/07/15/for-sale-various-new-watch-stem-nos/
Case back removal
Remove the SKX crown.
Remove the Seiko 7S26 movement from the case.
DAY wheel removal (swap to the NH36 for propely alignment).
*same procedure apply to the NH36.
Properly aligned DAYwheels on NH36.
Fixing the pre-cut stem to the Jumbo crown.
Installation is basically the reverse.
*Do remember to apply fresh silicon to those gasket !
Regulate the new NH36 to your liking if you have the timegrapher equipment.
I like the Jumbo crown as i feel its an upgrade with the extra gasket. Its also easier to manual wind the NH36 and time setting too.
Alright guys, thanks for reading. Hope the new summary tutorial helps.
