This Zodiac Calame uses an automatic modular movement by Dubois-Depraz (Caliber 2025 – base ETA ebauche). So it's essentially a non-chronograph movement with the chronograph feature strapped on its back (for lack of a better analogy).

Thanks banned, You know the watch is on the smaller side..You can't read the date out of the date window....but there is something about that curved crystal and thick case that I really like about this thing...I will never sell this one.Nice watch MGIRAZ! Don't see many of those around. I believe that movement is pretty rare too!
