Great Swiss Watch
Color: Green on Stainless Steel
High build quality. Super smooth movement. I've found that it loses time a lot faster than many of my Japanese automatics. The color options are great, but I wish there was more bracelet color diversity. High quality steel doesn't scratch easily. The date complication is awesome.
