Edited : 28/6/2018 (added my own custom made “S” crown for SKX007 diver mod)
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.
Many have asked me to supply them with an aftermarket crown and a suitable pre-cut length NH35/NH36 stem as a package.
OK guys, after many consideration and investment. I have decided to go ahead and custom made my own “S” crown for the SKX007 Supercharge upgrade.
They are custom made as close to the SARB059 crown as possible but with some improvement.
Lets have a look at the new “S” crown improvement :
The “S” crown
The pre-cut stem will fit nicely onto the “S” crown to provide a plug and play application !
They are made with “Double gasket” for added water resist application !
Additional crown “Bottom gasket” for even more water resist assurance !
So there you have it guy ! The “S” crown option.
Its offer “S” crown alone or a fix with the pre-cut stem.
