Allow me one tale of buying-a-watch-I-knew-damn-well-was-too-large-for-my-wrist.
The first Swiss watch that really stopped me in my tracks was the FC Slimline Moonphase Blue Dial. It's still an arresting piece. I'm romantically inclined, and the thought of a quiet timepiece (no seconds hand) on my wrist that really celebrates the ancient idea of timekeeping on a grand scale really appealed to me. And I mean "really celebrates," for the large surface area of the dial, combined with a date ring around the moon, and terribly attractive slender leaf hands focus your attention on time in an entirely different way.
And let's not forget the watch's other attributes: really quite nice in-house movement, developed long before this was "fashionable"/necessary; all functions set via the crown, which is large enough to use easily; one gets to admire the movement trough the sapphire case back; and overall, the watch is nicely finished. Furthermore, when I read all the reviews I found that industry-watchers had noted all of these things, too. So I tried one on.
It was obviously too large for me!
Now… my Speedmaster, at 42mm, looks perfect on my 7.25/18.4 wrist. But this FC (also at 42) was just… not at all the same!
Two years went by.
Then one came up on another forum at an attractive price and I just couldn't resist. I HAD TO HAVE THAT WATCH!
Two years later…
I NEVER wear it.
Do I love it still? YES! But what good does it do me? Sadly, no good at all.
Moral: Do not buy a piece that is too large for you—in any dimension! Watches are to WEAR (that is, unless you have the means to own many fine vintage pieces that really belong in a vault—"collecting" meant in an entirely different kind if way).
Again, this is the story of an amateur. And you have been cautioned here by pros! But (I'll admit) I like to tell stories. So I hope this entertains, as well as sheds some light on your plight.
Best of luck! And have a great weekend. FH
