Great detailed answere! Tag heuer AD? (Certified workshop?) this local place i took it to have been changing packaging for a long time on my watch but are not certified for TH although i’m fair certain they were.

I got my watch from my old company for selling fibre-optic for a value of 40 million Swedish Kronor. I love this watch but since 2016 when i got it, the date have been off, i reset it and then it changed and starts running away from the current date.. I left it to the same local workshop and they tried to fix this but it always comes out like this. You seem like you know what you are talking about :) if you have any solution.

Also i asked what it would cost to change the dial of my Aquaracer since i have the black background and i like the blue one. He said something like $800 which is roughly half the clocks value.
