Abercrombie and Fitch Seafarer how to identify parts

I recently purchased this Abercrombie and Fitch Seafarer manufactured by Heuer. I have been a watch collector for many years and this is one of my favorites. There is a missing crown and rotating bezel. I am hoping someone can help me identify how I can buy vintage replacements parts at a reasonable price. Are there part numbers or reference numbers for the bezel and crown? The case model number is a 2446 SF.

I cant find parts anywhere. The watch is too rare. I have one and need the unidirectional rotating bezel
