They are all technically very accomplished watches and the movements are completely hand finished! When was the last time you saw a watch below 20k with a interior angles!? Yes, probably never...
If money and case size were no object, I would pick the first one. If case size is an important factor, I would pick the third watch which has a case diameter of 41mm.
I have been invited to an Armin Strom event here in Bahrain and I have had the chance to speak to Claude Greissler, the technical director, also at Dubai Watch Week last year. I feel they are at the core of the independent community and they deserve to recieve much more attention from collectors. In any case, with any of the three models you are getting something truly unique! All of the pieces can also be customized to the owner's tastes as you have probably seen on their web site already. Kindly let us know which one you are going for and we are looking forward to pictures and perhaps even a story about your journey in ordering and owning one (or more 😀) of these watches.
Full disclosure: I am in no way affiliated to Armin Strom, other than that I like the brand, I had good personal interaction with them and I am considering buying a watch from the company as well.
