Hand-wound GMT is the detail worth dwelling on here — most GMT complications are automatic, so a manual-wind manufacture movement driving a second time zone is a genuinely unusual combination, and it changes the daily ritual from 'it winds itself' to 'you wind it before the second hand matters.' Été, summer, gives it the blue dial in this seasonal quartet; 39.5mm in steel with 30m of water resistance confirms it's a dress piece, not a travel tool despite the GMT hand. I'd flag manual-wind GMTs as a small, specific category on my scoring sheet — mechanically interesting in a way automatic GMTs rarely are.
