Well, this evening I received an IWC 3717 with bracelet from another member sam_tgg. I have swapped day and datewheel to genuine ETA (German language daywheel). On top of that relumed the hands, removed the crappy lume on the dial and sending the crystal to k2222 for double AR coating. I can't wear the watch but I am sure all the effort will be paid off in a few weeks time. Here is the result of hand reluming. My mistake that I put C3 dominant colour (3:1 mixed with C1). Here is the result of the reluming.
