doesn't look as if straight spring bars will even fit this watch. if it only takes curved end spring bars, what exactly are my aftermarket bracelet and strap options, and my limitations.
and try to find a curved spring bar. Both Jaeger and Girard use these. Be careful with the length of the spring bars as they should be 1mm longer than the distance between lugs Which dial do you have on your 8030?
All I would say for these curved springbars, make sure a professional checks them properly as the angle of the pin could also damage your case or not be fully engaged to the bottom of the lug hole. I have one such case, but won't get a second one!
