This watch is amazing when you think of the engineering that must have went into it. The miniature motors, gears and mechanism. Not to mention the radio control and solar power. All in a slim and lightweight package. Amazing. Had this for a few weeks now. No problems. Syncs OK every night with WWV. Only issue is the hands get in the way when using the stop watch function making the little sub dials hard to read. Wish they would go to 12:00 like the g-shock models. Also it would be nice to have included a light. For the same money I'm looking at their analog/digital version which does have a light and easier to read digital stop watch. However, I really like this little watch. I wear it to work everyday where it's great in the brightly lit factory conditions. It is much lighter and unobtrusive than my bulkier Citizen radio and satellite watches. Adding a 18mm deployment clasp really dresses up the appearance of the watch and makes me want to wear it more but can be a bit difficult to install. Had to carefully use vice grips to mush the strap material just a tiny bit to get the spring pin locked back in.
*Update - March 8* Now it's been a month and I am now bonded to this watch. I have since purchased another waveceptor with a metal band, gold indices and dual inverse digital display but I still prefer my all analog M410!  It just suits me to a T. And now have no problem reading the small stopwatch minute dial. Got it figured out. Easy peasy. Alarm is set for 5:45 a.m. and is loud enough as it syncs face down every night near me on the nightstand with the 12:00 position oriented toward Colorado.

Very pleased to see the watch automatically adjusted for daylight savings time with zero input from me.
