Help opening a seiko sports 100

Hello good afternoon

I'm trying to take apart this beautiful watch but I'm still rather new at this and not sure how take it off the case seems the crown is holding it in any advice? Thanks

Right above the word Japan is a hole that says "push". Push in there with a sharp tweezers point while gently pulling out the crown to release the stem. Then it looks like there is another "push" to release the lower crown & stem. Usually the crowns should be pulled out to the setting position before removal.

After this though, it is unclear how the pushers are captured so be cautious when dropping the movement out that you don't lose springs or internal parts of the pushers.

Check out this video for the stem removal.

To remove the pushers you'll need to remove the circlips which can be a very awkward job and best done inside a bag to prevent losses.

What's the reason for removing it from the case?
