Hello, I think that H Moser brand is wonderful and produces many amazing watches. The watch I would pick from them would have to be a perpetual one because of the amount of innovation that went into the watch as well as how unique it is. There are few, if any watches that offer this complication in a manner more elegant or simple. In addition, it was partially designed by Andreas Strehler, who is a genius. I would go for the perpetual calendar in their heritage collection. It may be over the top for some but I love it. I love unique and special watches and I have seen nothing like it. I also love the moon phase in their heritage collection. It is so beautiful. I think that if you want something more sturdy, they make a wonderful and elegant sport version of the perpetual calendar in the endeavor collection. It is actually reasonable waterproof so you do not have to worry about getting your thousands of dollars watch damaged
Hope this helps
