Hi everyone,
I’ve seen these 2 crowns on Breitling Top Time 810. Both watches are from 1969 (I checked). The crowns are both “original” yet they are somehow different. One crown is flush with the watch case and has more grooves. While the other has a yellowish bulge between the crown and case and has less grooves. I’ve seen the more flush crown on Breitling 815 so maybe it’s original to that model. Any idea which is the true original for these 810? Quite a subtle difference that I’m unable to find the answer online.
