Torn between Explorer 1 sizes

Merry Christmas to all! I’m hoping to get an Explorer 1 for myself soon to commemorate some mental health milestones. I love the versatility and ruggedness of the piece

I’m leaning more towards the 40mm vs 36, but you know what they say, nothing beats having strangers who don’t know you’s opinions :p

Appreciate any perspectives from owners re wearability as well! The 36mm is the first pic if not obvious
