I've always been curious about getting an alarm on a mechanical watch. I found that I've been using chrono functions more frequently lately as a timer for parking/cooking/etc, but an alarm would be more convenient for my uses. It looks like you wind the watch and alarm separately with different crowns, so there's no worry about draining your power reserve by playing with the alarm.
It seems to be a very reasonable price for an in-house movement with alarm, probably very comparable to Seiko entry level quality. It's much cheaper than any watch I've read about with alarm complication. I've only seen one useless review online of this watch, and it seems that he never actually had the watch in hand. I think this might be my next purchase. Once I figure out where to buy it, I'll post some pics within minutes of receiving it.
