My dad passed these on to me, any ideas?

 

This one is amazing.

 

This is a 176.005 Seamaster chronograph with an automatic 1045 movement in it. From the 70s, and quite nice. Even has the original bracelet. The inside ring of the dial seems to have some damage, though not sure from what. The minute counter hand may be a service replacement as it's not red/black, though it may also be original.

Hold on to it until we can get you in touch with a reputable watchmaker for servicing

EDIT: Provide more information about yourself and get a profile picture too please~! Or an @efauser will come and get you

too late.

 

Thank you for the information. Very interesting

 

My dad was an engineer in Pakistan and South America when he owned this, I imagine it got a hammering!

 

Correction Movement is Caliber 1040 not 1045[emoji736]
