Stührling Imperial Timecraft Tourbillon 42mm Lmtd Edition 1/200 w/Box & Papers
The Grand Imperium is one of the watches that changed that. Stuhrling took the ST-93301 hand-wind tourbillon caliber — 18 jewels, 28,800 vph, Côtes de Genève decoration, blued steel screws — and put it behind sapphire on both sides of a well-finished 42mm steel case.
