Note: I don't know if this watch is correct or not. The
base plate is nickel, but the two top bridges are
gold, not gilt looking, but polished. The winding
gears are polished nickel or chrome ? I will take
it apart in the future and check to see if all
numbers match. Looks fantastic the way it is. All
other info matches.
