The B220 series comes with 2 tourbillons for very cool visuals of accurate timekeeping. This is the watch that will make you look like a billionaire in a blink of an eye. This is the cream of the crop in affordable tourbillon watches. The 146g weight gives the watch a nice, balanced feel and the Hardlex mineral glass keeps the watch dial away from scratches. A great watch for fancy, visual time representation and for showing off. Best suits classy outfits and gentleman's manners.
The Automatic Tourbillon B220 is an automatic self-wind mechanical watch, which means that it doesn't require a battery. Hand-wound watches need to be winded before use. After the first winding, the watch will keep moving and winds itself automatically from natural hand movement if used at least 8 hours during the day.
Stop winding the watch when you feel the resistance. If you overwind the watch, the spring might break.
