Hi Guys, new member here. I realised that this is an old thread, just wanted to put in my 2 cents as I have just acquired a 2551.80.00.
@Tony, I don't see it either, it's super legible. But I used to and I can understand why.
I was used to wearing big watches for over 20 years, from 41mm upwards to 47mm. I don't know how I used to pull that off as I have a 7 inch wrist. Anything over 42mm - 44mm looks silly on my wrist, but I didn't care. I didn't realise how silly they were until I took wrist shots and reviewed them. Even at that stage I still didn't care and continued increasing my collection with large watches. Anything under 40mm I would laugh it off and mock them as women's watches without even giving them a chance to try them on or even see them.
When I first saw a mid size for the first time, I was taken back on how small it is. I immediatelly dismissed it as too small and did not even want to consider buying it. It wasn't until the seller asked me to try it on and....
take photos while on the wrist. I remembered I was laughing at how small the watch is when I was trying it on. After reviewing the wrist shots later that day, the realisation of how good and proportionate it looks on my wrist made me reconsider. I have to be honest it did take a day for my "watches must be BIG and NOTICEABLE so it's MANLY" brain to adjust. But when I made the decision to have a second look and finally pull the trigger, I realised why I got rid of my 41mm 2531.80.00 back in 2001. I remembered the watch just didnt sit right on my wrist, maybe it was the bracelet sizing but I just didn't feel comfortable wearing it. So it spent most of it's days in that red box and I finally had to let it go. Rinse and repeat with other even larger watches over the years and that's my collecting habit.
Now after 20 years, a Seamaster is back on my wrist. Only now it's a more appropriate size. I can wear the watch all day and it feels very comfortable, so comfortable that I may never take this off if I was a one watch guy. The only downside now is that almost all my other watches in my collection looks and feels larger and the silliness in the larger size is much more obvious.
Hope this helps people that are curious about the mid size. The key is to take several wrist shots (closeup and further away with your hand in the shot), or look at yourself in the mirror with the watch. Comparing the 2 sizes side by side in photos and videos will not help as the 2 sizes are noticeably different and your "MAN brain" will make you decide to choose the larger size every time. That part of me still exist as I tell myself this would be the smallest size I will ever wear.

Edit: Here are a couple of wrist shots.
