Lets gather all the service dials in one place. Omega only. Lets try and fill the thread with photos. Here is an Omega fitted dial, on my 2998-5 Note the painted logo, no step, and close spaced T's just visible at the bottom of the dial. Anyone else got a Speedmster Service Dial?
This rare 861 70’s era service dial arrived 3 years attached to this Franken put together in a nice 105.012-66 CB case. Note the dial is flat, TT markings and the raised logo is very close to Omega.
