My current aftermarket insert (shown on my Phase 1 watch at right in the 1st pic) also has raised numbers, but the placement of the dots is off & it lacks the flat-top 4 of the gen & new insert.
The insert NDT is selling was 1st available through Andy & I placed an order over a month ago (in tandem with a gen insert that arrived in a totally unusable state (in many broken pieces & some powder), which was returned to the seller). Unfortunately, my order fell through some cracks, but is supposedly now en route to me. I can provide more details once I have it in-hand. However, I do know that these inserts are made to fit the gen 6542 bezel, so they should fit any aftermarket bezel that is made to the gen spec. I have a gen bezel, so fitment is not a problem, but you should check with the seller if you are trying to fit this (or any other aftermarket insert) into an aftermarket bezel
