Tonino Lamborghini 4 Screws 4850 Men's Watch. The 4850 model makes explicit celebration of the iconic characteristics of the automotive world: the screws, the strap and the counter dials of the Tonino Lamborghini 4 Screws are all evoking the Lamborghini family heritage. The 4 Screws model has a Swiss made chronograph movement. The automotive inspired details are several: the dial background design immediately echoes motor-racing start/finishing flag, the left pushers unmistakably evoke aluminum sportscars pedals; counters look like speedometer and rev counters. The mechanical design inspiration also emerges from the strap made of perforated leather like the sportscar interiors, but above all it comes out from the iconic four bezel screws, which look like the ones used to close the cylinder heads of the car engines and here represent the dominant style feature of the watch.
