De Ville Trésor Co-Axial Master Chronometer Petite Seconde

Ref. 43553402110001 takes the Trésor formula — 40mm, hand-wound, 30m water resistance, leather strap — and moves the case into gold with a green dial and an offset small-seconds register, a materials-and-color combination I don't see often even across a catalogue running past 4,000 pieces. Green reads differently in a gold case than in steel — warmer, less clinical — and the offset register keeps the layout from feeling too formal for a color this unusual. Mechanically it's the same manual-wind approach as the rest of the Trésor line, so the premium sits entirely in the case metal and the dial. On my material-coherence axis, gold and green either works completely or not at all — this one works.
