Nicolas,
Sorry to hear that the Prince proved to be a big dissapointment to you. I concur with you on the cluttered dial. What I won´t deny is the decoration they made to the movement, proves to be one worth staring at for hours at a time. In my humble opinion and limited knowledge.
I am sure you will find something more appealing to you in a tank case.
Personally, the type of Cellini I am most fond of is the 5116, which is part of their Classic Line. The only downside is that the case size is a bit small. Gladly the folks at JLC came out with the Ultra Thin this year at a very decent 38mm...I will have to check it out...
Best,
Alex
