Here is my snk809 that I upgraded with a AR coated sapphire crystal and SKX009 dial last year. Im a fan of the 7s26A movement but I wasn't happy with my 7s26c. After two years of owning the stock movement, the time grapher numbers started to tumble. I bought a NH36 and a new set of 6105 look-alike hand set. I also switched the day date discs to match. It is a little difficult to wind because the crown is so small, but I like it. The swap is pretty straight forward, just like an SKX swap. I wont do a write up because everyone and their dog has done a movement swap guide.
(7s26 on the left & NH36 on the right) The 7s26 has a black plastic spacer while the NH 36 has a grey spacer, no need to swap the spacers they are the same diameter.
(Swapped day date discs, now I have to cut the crown to fit.)
