The Laco Palermo 861966 model features a scratch resistant sapphire crystal and the 42mm case design houses a Laco 21 automatic (self-winding) movement. The Palermo has a black Type B (or bomber) dial with large minutes and a small inner hours scale. The hands and dial markers are treated with orange color SuperLuminova for readability in the dark. Like the original WWII Laco watches, there is no date window. Includes a really nice aviator leather strap with rivets like those used in WWII.
