DJ or DJ II?

[baybombers]

I am closing in on a professional/eductational goal and once I have completed it, I will likely be buying my first Rolex. Initially I was set on a Datejust with the black stick dial and oyster bracelet. I went to the AD this weekend and tried one and it felt a little small. I then tried on a Datejust II with black stick dial and I am now torn. I am used to wearing a Baume et Mercier Classima GMT (42mm) so I don't know if the Datejust feeling small was just a natural reaction based on what I am used to. To me the DJ II is a dress watch with sport watch dimensions and would likely be fine to wear with a suit and fine for my field (investment management). However, I am also worried that in a few years if the pendulum swings back to smaller watches, the DJ II will look dated. On the other hand I am concerned the DJ is more exclusively a dress watch and wouldn't work as well for casual settings/dress.

Would someone who has gone through this same debate or owns both be willing to comment?

Thanks.
