My initial preference is for the manual because I don't want a subsidiary seconds dial on a dress watch. I also think 43mm is likely too big. My ideal version would be a manual, no seconds hand, 38-40mm and with a two-level dial like the automatic (but no third level, obviously, since no seconds dial). But I am open to seeing how the different sizes look on me and automatic won't be a deal killer.
Also, I don't need a watch.
im with you on this. for this watch i would say to go without a subdial, its simplicity is its beauty. also, manual feels right for this watch. and slimmer, correct? as well, after meeting you, your build and wrist size would be far better suited for a 38-40mm, particularly for a dress watch.
and lastly, need has nothing to do with it. if you like, and can afford, do it. do it for me, buddy.
