First watch build questions

[DrG]

Hi everyone! 

I am currently in the process of building my first watch. I have sourced the parts from ebay and decided to go with a Miyota 8215 movement. I believe I have everything I need, have learned a lot from watching the videos  , however I am still scratching my head on a white movement ring that the Miyota came with (picture attached). Is this the dial spacer ring or does it function as both a movement ring and dial spacer? The case I purchased comes with a movement ring (however I have to purchase the clamps and screws, which I have already found on Esslinger). If this is not a dial spacer, I am assuming I would need one so the date ring doesn’t get stuck, however I am uncertain if the dial spacer is totally necessary. 

Thanks in advance!

Fix the movement in the case with the one you find inside the case. Put it around caliber once inside. The one you received with the caliber put in a tray.... [emoji16]

I consider the case dimensions and those of the movement Dr ranfft mentions.
