Nice bro! Looking forward to seeing it set up on the watch. Might take a while though, logistics services now all slow down because of covid.
The movement angle is a rather interesting subject. The MT5402 is built for Tudor by its subsidiary Kenissi, and they really know what they're about seeing how their efforts have won them what, 5 GPHG awards already? Having said that, Kenissi also makes cals. for Norqain, Breitling and Chanel. Here's an A:B of the Norqain NN20/1 and the Tudor MT5402. Very similar in general appearance, same power reserve, same no. of jewels. Reckon the only difference is rotor and finishing.
I reckon the base model of both movements are the same, just finished to different end requirements by the client. And I also recommend checking out the Chanel J12 also, which runs a cal.12.1 also by Kenissi. Elegant rotor and finished more nicely, likely because its on a clear case back. Similar looks, differing only in the number of jewels and date function. I reckon Tudor is definitely gonna be putting out more BB58 or similar sized time pieces, probably some in interesting and attractive color combinations. New watches means new hype, might mean better resale value too perhaps?
