some of my favorite watches

these watches are some of my collection. found some info on some of them except the transitional watch in the 4th pic. what i do know is that on the movement it says mirinda swiss. 7 jewel 2 adjustments. it has a hinged back. on the back is says "scepter- warrented 10 years- 10 1/2 ligne and the # 4474423". it is engraved on the back "Grayce". only thing on front is swiss. it seems to be a quality watch and it runs for a a while then stops. probably needs cleaned and oiled. found a little info on case but thats all. if anybody has any info on it i would appreciate it. the others are a gruen 835 movement from the 1920s i believe. inside of the back it has "gruen- 14k gold filled-cincinnati-74/153-2042848. the hamilton is a 986a movement. with serial #2132556 on the movement. it is from 1925-26 according to some websites. it is 14k gold and it runs for a few then stops. i guess if i was that old i would too. the last one is an elgin 744 movement. the crystal is missing and it doesn't stay running at all. it makes about 3 or 4 tics and stops. if anybody has more info on these i sure would like to get it. a value would be nice also. thanks for reading.
