Being a new broom, I'm still wearing the Nomos Tangomat GMT from Saturday, so here's a quick iphone shot of the open case back showing the in-house Xi caliber taken at office as per your request.
Very precise so far but true accuracy will have to wait till after a month.
Heat blued hour, minute, second hands against an off white dial looks much nicer in the metal...
