The PD625 series is one of a kind skeleton watch that comes with a tourbillon attached to it. The gorgeous, well-balanced watch has a 30-hour power reserve and a protective Hardlex window to prevent scratches to the dial. Due to the semi-heavy design, the PD625 feels much more valuable than what the outstandingly affordable price lets in on. As an additional benefit, the large dial makes it easy to see time even at low lighting situations. This watch is for a man who wants to stand out from the crowd in a classy way.
The Automatic Tourbillon PD625 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 10 hours during the day.
Stop winding the watch when you feel the resistance. If you overwind the watch, the spring might break.
