I need some advice concerning the 1503/825 Seamaster bracelet on my 2531.80 The watch is from the 90ies and has got a tritium dial. The 825 end links are different most of the ones I saw. Not stamped and one single piece. Did the endlink design changed from the early one which where just single pieces to the one that are made of more pieces fixed with a screw? I attach some pictures of the bracelet and from the end links. Thanks guys
