Omega 3876.50.31 Manual Winding Watch

The Omega Speedmaster 3876.50.31 "Moonwatch" is a 42mm men's manual winding watch with a stainless steel case and a black analog dial protected by sapphire crystal. It uses a 1866 caliber mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks 8 times per second which gives the second hand a smoother movement than a quartz watch which ticks once per second. The watch should run for up to 48 hours when fully wound before needing to be rewound.
