ecelis

I knocked my Rolex Submariner MBW 1680 against a fence in my yard and the bezel fell off. I could only find the bezel and not the washer/spring that goes between the bezel and the watch and now the bezel is very loose and spins around to easily. I hope someone can help me with these questions:

1) I see that there are 2 parts that hold the bezel tight a tension spring and a friction washer. Is this correct (see attachment)? If so, which one goes first?

2) Where would be a good place to order these parts online?

Thanks for your help
