6536/1 bracelet question

[ferelurbannigel]

Hi there, this is my first post so please don't shoot me down in flames if I've posted to the wrong section or asked a silly question. Here's my problem...
I've got a 1959 6536/1 sub, it came with a USA C+I 1-73 spring bracelet which fits OK on the lugs but it's a little bit wobbly. So, after a bit of research (obviously not enough!) I forked out on a 7206/80 1-65 bracelet which sort of fits OK (you end up with a gap underneath between the watch and the end links and it's not a perfect fit - it's as if the end links are a fraction of a millimetre too wide and I mean about 0.1mm). I've noticed other 6536/1s for sale (even the very expensive ones which also come with a 7206/80 seem to have the same issue). So my questions are would a 7206/58 make much difference? Or would even a 9315/280 or 93150/580 be better than the 7206/80. Thanks!
