I need some help please

[RobsWorlds]

I have an SD43 that I got on this site from BK and I love the watch but I dropped it on the tile floor and it landed on the crown. Now the crown is tough to turn, it also knocked the #6 off and it’s loose in there. I wanted to see if you could repair the issues and water test it as well as take a look at the movement and let me know what you think. Maybe chance to the 3235? I would appreciate the help., I can’t get a hold of BK. Thanks Rob
