This beautiful new Union watch is currently under 'evaluation' on my wrist:
My watchmaker even partially disassembled the movement, so that I could study the big date mechanism.
Until now, my experience with that elegant timepiece is very promising, but I will inform you in detail in my complete review, which will come here in about two weeks.
If you have any questions or suggestions about what I should test specifically ("how does it react to a 5 pound hammer?"), please let me know, so I can include it in the report.
