F.P. Journe Tourbillon Souverain TN

F.P. Journe Tourbillon Souverain ref. TN “Platinum, Grey Dial, 40mm”

Up for grabs is an F.P. Journe Tourbillon Souverain Ref. “TN.” Produced between 2003 and 2018, this example is presented in the classic configuration of a platinum case with a white gold (grey) dial. This example is from 2005. “TN” stands for Tourbillon Nouveau — the later evolution of the Tourbillon Souverain, incorporating both the remontoir d’égalité and independent deadbeat seconds (seconde morte). This constant-force mechanism enhances timekeeping performance, while the deadbeat seconds displays true seconds in discrete one-second jumps — a rare feature in modern wristwatches.
