I want to buy the Longines Ultra-chron Classic but I'm not sure which size to pick.

Everybody (gf, watch seller, customer, family, AI, etc.) has told me the 40mm looks better as it's much more proportionate, but I just like the classic look of the 37mm one when I look at my wrist.

For reference, these are my measurements:
- Height 6'2'' (187cm)
- Weight: 185 (84kg)
- Wrist width (6.5 cm)
- Wrist circumference (18.5 cm)

Would love to hear your thoughts! I know the images are not ideal to see the difference, sorry....
