Thanks, Chuck!

The watch has:

'11063 V' - etched between lower lugs.

'387884' - upper lugs.

BREVET
'503.305'
M.R.P.S.A

inside the caseback.

Cal. 12

Guess this makes it a 11063VNT?

Anyway, am real happy with this find ( even with all its battle scars ) as this is my first vintage Heuer Chronograph. =)

Another question though,

Where can I buy a replacement crytal for this watch?

I suspect that this watch has an aftermarket? crystal, as there appears to be a cloudy film underneath that reflects the applied indices when light hits it at certain angles.

Even tried putting it with the caseback open inside a Ziplock bag with some silica gel overnight, to no avail. lol

What a wonderful resource 'OTD' is!

Thanks again to yourself and Jeff Stein for making things easy for us.
