Hi @claraxx
Welcome to OF.
It’s generally customary for new members to introduce themselves but, that said, it looks like you have a nice watch.
Better, sharper, larger photos in good light would help but, based on your photo, it’s possibly an early 1950s Seamaster model 2577 with a 351 bumper automatic movement.
Again, in the absence of better photos, it looks like the dial may be original which is a big plus.
Don’t try opening the caseback yourself - unless you know what you’re doing but, if you send it for a service (and it probably needs one) get the watchmaker to photograph the movement and inside caseback.
Don’t bother going to ‘the guy in the Mall’ who replaces batteries and, if you post the area in which you are, someone should be able to recommend a good and reasonably priced local watchmaker.
So, post better photos.
If I’m right about your watch, this is my 2577 cal 351 gold-capped bumper.
