I voted for keeping both, but then I saw that you find the 124060 uncomfortable.
I also have a 124060, and my experience was that it took a while and a few trips back to the dealer to get the bracelet dialed in just right. In my case it was really important that the clasp sits right in the middle of the wrist, and I actually had to go back to the store twice to find the "sweet spot", although I had never had such difficulties with having a watch adjusted before that. Now the 124060 is really comfortable, but like I said, it required some work.
But whatever you end up doing, my advice would be not to sell the 14060M. I did, I will never stop regretting it...
