The IWC Portuguese Yacht Club Chronograph Boesch watch replica is a limited edition of 150 pieces. As all other IW3905 models, the case measures 43.5mm across, housing the self-winding caliber 89361 chronograph movement.
IWC first collaborated with Busch in 2009, when it introduced the Aquatimer Chronograph Busch in celebration of the 80th birthday of the boat builder.
It is said to be inspired by the Boesch 620 Bimini, which explains the rich brown tone of the dial and the -real- mahogany inlaid in its case back.
Now the two Swiss companies have once again put their heads together, leading to the IWC Portuguese Yacht Club Chronograph Boesch copy watch IW390504.
