## Questions & Answers

**Q: Does "automatic" mean self-winding?**
A: Automatic absolutely does mean, “self winding”. There’s no battery and no capacitor, as someone else claimed. As long as you wear the watch at least 10 hours a day then you should never have to hand wind it. Moving your arm throughout the day causes a rotor inside the watch to turn, which winds the watch and will not allow the watch to be overwound by the rotor. Once the main spring is fully wound, it provides anywhere from 40 to 120 hours of reserve spring power (depending on the brand/model), allowing you to place the watch on your nightstand while you sleep or even put it in a drawer over the weekend, and the watch will keep running until you put it back on again. If the watch is stationary for too long and all the energy from the main spring has run out, then put about 5 full turns on the crown, reset the date and time, put the watch on and you’re good to go. The self winding rotor will finish winding the watch for you and keep it wound indefinitely as long as you wear the watch at least 10 hours a day.

**Q: How do I stop the second hand to set the exact second? I pull the crown out to the second position, but the 2nd hand doesn't stop.**
A: Absolutely do NOT put your watch on a magnet. You will magnetize your movement, and kill your accuracy. 

The 7S26 movement is non hacking, so you cannot stop the seconds hand for precise time setting. Look for something with a 4R35 or 4R36 movement if you want to set precise time.

**Q: whats the strap width? the page description says 17mm but i cant find one in that size :/**
A: Lug-to-lug width for SNKL43: 18-mm. Measured it two days ago to order a NATO-style watch strap.

**Q: Wore my new watch for twelve hours, took it off for twelve hours and it stopped. Is this normal??**
A: To me that is not normal. Sincethis movementis supposed to have an power reserve of 41 hours when fully wound spring. Eighter you are not moving your arm much or the watch is defective. I used mine black model now for about 2 weeks and it never stopped. I wore it now not for about 19 hours and it still runs.  Keep in mind that the rotor on the back only turns at an steep 90 degree angle. The self winding weight will not turn on an shallow angle - so it winds only confidently with some wrist up and down movement. Otherwise this is the best watch ever for me. I ordered 2 when the
