In fact it depends on the size of the cuff. The watch is not thick so it goes very well with it. I would say that you won't have more problems with this watch than any other dressy watch (except the ultra thins of course).
Take your time to think about it, try them again but try also to see how it feels during the day to imagine this 3 Hands watch on your wrist ... instead of a more "complicated" one, as it seems that a complication seem to be something you would like too.
I must say the 1815 is amazing concerning its look, finish, the light reflection etc ... But, as I see that you also would like a complication, I must say that I had the same thoughts before buying the 1815. Now I feel that a complication is missing and if my budget had been higher at that time, I wouldn't have chosen the 1815 ... This is really a personal feeling but if you think it can be important for you to, take the time to thnik about what would be to wear it without a complication.
To conclude, as It seems to be a watch you will only were during special dressy occasions, I would say the 1815 could fit perfectly too, and you will be able later to chose another more complicated watch (taking into account your experience with the 1815).
Best,
