Safari Offshore or Rose Gold Dual Time

[Barry C]

I currently have a 26170ST.OO.D091CR.01 (Offshore Safari) but with ongoing accuracy issues I have mentioned on a previous thread, I have an opportunity to do a deal part exchanging the Safari for a 26120OR.OO.D088CR.01 (Rose Gold Dual Time). I love the rose gold of the dual time, and like the complication, but have doubts about the size at 39mm being too small. I can’t try the watch for covid reasons. My wrist size is 7” And the Safari looks good on me. Is 39mm too small for my wrist? A picture of a Royal Oak 39mm watch on a 7” wrist will help. Second question, is this a good move swapping these two watches? Thanks!
