Three of my favorite watches. I would not be able to give up either Speedmaster if I had to go down to three watches. On the third, it is tough. The AT was a grail watch for me, but I don't often wear it. I have owned it for 7 years. About due for a service. It's from 2013, but I bought used used in 2014/15.
Three of my pre-war (that's the Great War) Illinois railroad approved pocket watches. From left an 1887, model 2, grade 5; a 1904 model 6, grade Bunn Special; and a 1911 model 5, grade A. Lincoln.
The one in the middle is technically for my wife as it is 31mm but it does wear somehow bigger...
1946 (calibre 27) for the middle one, 1954 on the left (calibre 27B-1)& 1958 (calibre 26.9-21) on the right.
