Each bank has its own time limit for pending charges
If they aren't replaced by 'real' charges within that timeframe they just drop off.
Apple seems to be hit or miss on whether they 'test' your payment source with a pending charge (usually $1). I ordered two apple watches, one of which is in the first wave and one in the second. I have not received any pending charges relative to either one.
Incidentally, I also never received a confirmation email for either my preorders, which were both placed on 4/10, one just a few minutes after 3:00 a.m. PST and one several hours later. However they both show as processing so I am not concerned.
