Product Info

What stands out in this watch:
  • Premium super tough Mudmaster watch, impervious to mud. Made for all the dirtiest adventures, caving, climbing, riding, potholing; you name it, this watch can take it.
  • Built into one side, a triple sensor gives information for altitude (altimeter), air pressure (barometer), and compass.
  • With a single press the second hand swings free to point to magnetic North.
  • The barometer function gives you a guide to the current air pressure, good for guaging upcoming weather conditions. The altimeter indicates the current altitude above or below sea level.
  • A thermometer built into the watch allows you get a more accurate reading of the ambient temperature.
  • Multiband 6 radio controlled timekeeping for local and world time. Every 24 hours, the watch will automatically sync the time to the local time to ensure the time is accurate.
  • Listed around the dial, the cities indicate the different time zones you can set the watch to. Once set, the watch will set itself to the local time.
  • The LED backlight is super bright for great visibility in the dark.
  • Both the hands and hour markers are coating with a film that gives brilliant visibility for long periods after only a short time in the light.
  • Casio Tough Solar technology powers the watch by light. With this eco-friendly feature, you never need to replace the battery, also helping maintain the water resistancy of the watch.
Additional features:
  • Suitable for everything from showering to diving and everything in between, this watch is rated for 200m water resistance.
  • Home hand correction: this function ensure the watch continuously displays the correct time. Adjusting the hands if the watch has been knocked out of place, of suffered minor exposure to magnetism, this means you'll always be on time.
  • Sapphire crystal glass with anti-glare coating.
  • Case size: Approx 56mm.
  • The day and date are both displayed on the digital screen under the main hands.
  • 2-year warranty from Casio plus an extra 1-year from WatchO.

    Beast watch!!!! It took me a year of research before I purchased but it was worth it. 5-star service!!!! I did my research before I purchased this product. Came across this website. It was the cheapest and best deal on the market. I had the buy one take one offer plus they upgraded my delivery to next day for free. I don't normally do feedback coz I couldn't be bothered but this one was I thought is the least thing I can do for them for their fantastic service and excellent product. I will purchase again.

  3. Best Price & Service

    Posted by on

    I would like to congratulate Watcho both in terms of customer service (Special mention for Kiran), and on price. I spent a lot of time researching the best price for this model both nationally and internationally, and when you factor in delivery and tax, Watcho were by far the best price. To recieve a free gift on top of that has already got me recommending the site to others

  7. First class service and price!

    Posted by on

    It is beautifully made and appears to work perfectly. Very happy. I bought from WatchO because they were the cheapest but also because they had great feedback. I had a phone call from them the day after ordering online just to confirm delivery address details and the watch arrived the next morning. I really can't recommend them enough. Brilliant.

  8. Highly Recommended

    Posted by on

    Great piece of kit. Next time I'm lost on top of a mountain in freezing temperatures. The thermometer, altimeter and compass will come in handy. Very quick delivery, good communication, received in perfect condition. Faultless service, more than happy to use Watcho for my next purchase.
