Can anyone help with a value for this ,
my father has had this since the early 70s , he was a saturation diver and worked for the likes of comex and warton williams, also went on an expedition with Jacques Cousteau .

 

Hello, Try to give a look here:

This is also a good thread/link.

Also post lettering inside clasp, someone here will be able to tell you if bracelet is vintage or new.

 

I’m no expert but I’ve never seen a 1000m /3000ft dial before.

I’m sure someone with more knowledge will be along soon.

 

There are members who know more about this than me, but one thing that is obvious is that the dial is incorrect. The dial is probably from a Omega Seamaster 1000 (166.093) and likely replaced during service.

 

Oh, I like this watch!

 

dial is def a replacement .... but the most important is the movement number to see if it was also swapped or is still the original one.
regarding the history from your dad ... best would be if u can prove it with pictures then it might add some value

 

pretty cool heirloom

 

This isn't the same watch in all pictures.

Front shot no C Case
Back shot C Case

 

They are all ‘C’ cases from the back!

 

Never knew that, thanks

 

clasp

 

It’s a vintage strap.

 

Some more history and any pictures of your Fathers work would be great.

 

is there any number engraved on the caseback?

 

take a look at the pics ... no its no protoype

 

Dial seem to be fake.

 

... after u read the post of mr. xy on instagram

 

yes
