Advice 15400/15450 on 6.8 wrist

[Frits1980]

I have a 6.8 (17.5cm) wrist and i am trying to choose between a 15400 and 15450 white dail. No AD close by to try them on so i will be buying the watch online. So i realy could use some advise so that i can make the right choice.

I have sub dates (ceramic) and a sub 14060m. I can wear both models fine altough have a slight preference for the 14060m sizewise for my wrist. I'm not a fan of big/oversized watches.

I'm leaning towards the 15450 but some YouTube videos with the 15400 on a 6.5 inch wrist is making me question again as it looked fine and propotional.

Its a bit hard to measure but i think the top of my wrist is about 2.16 (5.5cm) so i asume lug overhang won't be an issue with the 15400

Here is a pick from my sub on my wrist:

Please let me know what you think. 15400 or 15450?
