Where have these watches been?
Color: Grey on Black Fabric
A wonderful looking and wearing (with some wee modifications)watch. I originally bought this watch with the textile band but soon discovered it was not a marriage made in heaven. I swapped the bracelet for a leather aftermarket deployment bracelet and it transformed the watch for me.

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.
