Just because he would have a view onto things that is different from mine. In the contrary, the respect exercised on this site for different opinions is one of the things that make PuristSPro so special.
That said I completely share your idea of steel being the superior case material exactly for the reasons you mentioned. Even if in the meantime I found the WG case to be consistent with the very special movement of the Chronometer. But I am wearing it rarely and with care because of the soft case.
Seems to me that you are a "movement guy" like I am. The idea to invest into the movement rather than into the case material appeals to me.
The Diary is a great choice! A very special movement, a unique execution of the alarm complication and surely a great addition to your already impressive collection of G.O.
Best, Martin
