Found this amongst my dad's watches not too familiar can someone please educate me

 

Hi there, this is model ref. 11630 from the mid-1970s.

 

Great thanks is this an orange boy?

 

No, afraid not. These are a different model

 

Ok thanks

 

Have you been able to figure out which exact reference is this?

 

It is an MH, according to a Heuer catalog from 1974:



Even though both black and silver dial models could be specified with a Tachymeter or MH bezel, apparently Heuer gave the black dial the MH reference and the silver dial the T reference.

 

Ahh great thanks for the info

 

I was thinking it was an MH as well but the minutes dial isn't orange.

Can you help me on my other post too in watches just brought I'm at a loss on the omega

 

You guys are great

 

It is, but yours has faded. See the remnants of the orange bars on the minutes counter at 1-5, 10-15, 20-25

 

MH just means that is has an MH bezel...
And it does. It's just a regular 11630... MH if you want..

 

Though the bezel could be specified at a dealer to be either MH or tachy, Heuer did refer to the black dial as the MH model and the silver dial as the T model - see the descriptions in the catalog above
