A great watch for a steal! This one has the Sellita SW200 26 jewel movement and runs as accurate as a quartz watch. Right out of the box it lost approx 2 seconds during the daytime but when I put it down for the night in the 12 up position it gains 2 to 3 seconds. So in the 2 weeks that I have the watch (GL0063) it's still pretty much spot-on.
Finish is impeccable and I love how the domed sapphire merges with the GMT bezel. Legibility is outstanding. The only negative that I can come up with is that the lume isn't quite as long lasting as on my Combat Sub.
