## Questions & Answers

**Q: Why does my watch randomly stop? It works when I put it on and have to manually adjust the time. Is that behavior normal?**
A: The movement in this watch gets its energy from the movement of the wearer, if you move your arm the watch winds. Fully wound this movement can run for around 40 hours. If your activity level is low your arm movements may not be enough to wind the watch fully, so you may want to manually wind it every day.
 
The interesting part of a watch like this is that it keeps time by using gears and springs, not electronics. A quartz watch is more accurate than the most expensive mechanical watch, gaining or losing at most one second per day.

If the watch has stopped first wind it manually, then reset the time and date, and you should be good to go. These watches cannot be overwound, so give it about 40 turns.

**Q: Why does the dial only read "made in"? Are these not made in Japan?**
A: I had the same concern, especially for the green dial where only "Made in" appears in most photos (1st, 4th and 5th). It arrived with the full phrase "Made in Japan" in tact, both on the bottom of the dial and on the rim around the transparent back, i.e. everything OK (sold and shipped by amazon.com).

**Q: Can you swim, j work on boats the watch will always get wet.**
A: According to most standard descriptions of water resistance ratings, with 10bar of water resistance, it should be just fine for swimming and even snorkeling. The water resistance rating is based on the pressure induced by depth causing water to seep in past the rubber o-rings. The more pressure it's rated for (i.e. 10 bar) the deeper it can go, and for a longer time spent immersed in fluid. Many "dive" watches are rated to 20bar (200 meters or 600 feet) and that seems like an impossible depth you'll never reach but if you keep the watch submerged long enough there is a chance of intrusion. 10 bar (100 meters / 300 feet) therefore, should be more than adequate for most underwater excursions for a limited amount of time. 

Another factor I often consider is that watches rated for higher pressures/depths are built a little tougher (and are a bit larger as a result) so it's worth considering if you're looking for a watch that will withstand the rigors of daily wear for work on a boat where you might accidentally hit it against, say, stainless steel, railings, and other metal objects. I'd look for brushed metal cases and sapphire crystal for a tough tool watch. Ymmv.

**Q: El 012 y 015 la esfera es negra mate? Cual de los dos es más recomendable? Hay algún brazalete alternativo que le sirva? Gracias**
A: Cualquiera de los dos son excelentes,  no te arrepentirás.  Y si puedes buscarle correrás alternativas en sus medidas, pero la verdad, prefiero no cambiarselas para mantener su diseño y elegancia original
