Hi all, first post, so before i get to my question, thought i would introduce myself a bit. completely new to the world of watches. my watch of choice for most of my adult life is a timex/casio digital watch. bullet proof, multi-functional and cheap. over time, even though i have acquired several nice watches through gifts and inheritance, i almost always wore the digital . my favorite non digital is the gold longines , a heirloom passed down from grandfather-father-me. i really like its elegant simplicity. it fits well on my wrist and is very comfortable. not ostentatious. i wear it for more formal events. the rolex was my dads special watch. its also a nice piece, but a little thick and heavy for me to wear for a extended period of time. perhaps changing the band, but thats how my dad liked it, so i keep it as is. never really gave the watches much thought, but for some reason, a couple of months ago, i started looking at watches on the computer. i guess i was curious about what makes a rolex a premium watch, and eventually i found the seamaster chronograph circa late 1960's. to be honest, i was completely ignorant of omega as a brand. anyway, i ended up buying a 1968 seamaster chronograph with 861 movement. just received it today. i really like the aesthetic of the watch, and it fits quite nicely on my wrist. the lugs are a bit stiff to pressing but work fine. my concerns are: 1) i think everything is authentic, but maybe not original? 2) the movement inside the case rattles and moves a little bit if i shake the watch. when i hold the crown everything seem stable. i can move the dial slightly by moving the crown. something is loose and im hopeful it is not a big fix. i have included photographs- my first attempt at watch photography- tougher than i thought to get decent photos. hopefully these are good enough. im not sure if i should try to remove the case to take photos of the movement. any thought and comments would be appreciated.
