Hi. I love the chart - this is very helpful. I apologize in advance if my question is answered elsewhere in this forum as I am new here. Anyway, does anyone have a history of when each bracelet was changed in the sports watches (i.e. original riveted to folded to solid to locking clasp to introduction of jubilee). I just need a good guide to see if the bracelet that comes with a particular vintage watch was correct for the year of the watch. Thanks.
