The Luminor 1950 Rattrapante 8 Days Titanio is a split-seconds chronograph with vertical clutch and twin column wheels. It contains the the P.2006 proprietary movement, with an 8-day power reserve thanks to three barrels containing mainsprings. The 47mm case is made of brushed titanium, as are the buttons. The distinctive dial is black, with readability ensured by luminous dots and hour markers, and punctuated by a blue split- seconds hand and a blue minute counter hand. The watch is water resistant to 100 meters.
