No, I donāt think you have anything to worry about. Whether the springbars are white gold, steel, or otherwise, if you arenāt proficient at changing them youāll scratch the inside of the lugs anyway. But who cares, itās on the inside ā no one else sees it. Being afraid to change them and sticking with one strap is worse IMO. Straps have the ability to transform a watch and youād be missing out.
Technically steel is stronger than white gold but both are just as secure for spring bar purposes. Never had an issue with steel on the springbar holes instead of white gold.
I change straps for a living ā so long as youāre careful, diligent, and do it in a brightly lit area, youāre going to be fine. And then test it right after before you wear the watch. It will be so much more enjoyable when you get to change out straps yourself!
