Don't worry about the SW200 movement! I have had my C600 approximately three weeks now , and it has been worn daily for "break-in" during this time. After a couple of days, the watch settled into a fairly consistent gain of 6 - 8 seconds per day. Now it is running within +/- 3 seconds per day! This is as good as, or better than, most of my ETA 2824-2 movements. This watch is a delight. The electric-blue face is bright without being brassy. The "seconds" hand is long and gracefully slim, so that despite it's length and arctic white color, it isn't distracting. Tritium illumination is unsurpassed for readability at 3:00A.M. The inner portion of the hour and minute hands ( as well as the entire second hand ) is conventional luminous paint. This disappointed me at first, but in practice, this serves to provide the super-bright initial illumination that you will need to read the time when you step out into the dark from a lit room, or into a dark room from daylight. After your eyes adapt to the dark, and this glow has quickly faded, you will be able to read the time from the tritium markers. I'd like a tritium dot on the "seconds" hand, and the rotating bezel NEEDS a tritium dot, but otherwise, this watch is as close to functionally perfect as you will find - at any price.
