Hello, new fella here!

Seriously smitten by the Smiths Everest and have cleared a new watch purchase with the 1st National Bank of Wife...

but I am on the fence with the 40 and 36mm choices.

I have a very flat, 6.5 inch, wrist and as such wanted to reach out here and see if anyone could offer me a side by side comparison photo of the two sizes (or even better, a 40 and a 36 photograph on the same similarly sized wrist to mine)?

Thank you in advance.
