I got an orange 42mm PO from Trevor a couple of months ago for ~150 with a DG4813 as well. It's the only one of my three reps that didn't need any work on the movement. The two eta (one swiss, one asian) movements I had both needed servicing soon after purchase but the 4813 has been perfect the whole time. It gains a couple seconds per day, which is exactly what I'd like it to do.
