Good day to all. Newbie here interested in purchasing his first Muhle Glashutte Rasmus Dive Watch, or perhaps a Sinn U1. I really like automatic movements. Currently, my everyday watch is a Marathon GSAR. I find the looks of the Rasmus 1000m beautiful in a purely functional way, like the Sinn, but am concerned about accidentally purchasing a fake. A search of the web didn't really reveal any "tells" to watch out for when examining this model. However I did find a lot of info concerning replica Sinns. Can you guys help me out, what are some of the aspects of used Rasmus I need to be aware of? Thanks to all.
