Ok well ,the one that odd boy has very kindly posted is a late omega service/replacement dial which has light white thin lume wedge 2 and No concentric circle [if it’s the conventional modern version made by SJSwiss nl] and is the second of my photos
The second service /replacement dial is the one exhibited on the tea towel by Omega Rolex which has concentric but no wedge 2
the original has concentrics and a wedge 2 and a heavy over lume Carmel colour and is is made by singers and is the first of my photos
It’s very difficult on a low resolution photo to distinguish the modern replacement but it’s crisp thin low load white lume is the clue
On high resolution you see no circles on the sub dials
The feet are 4 mm and the diameter of the feet are 0.8 mm they are thus not interchangeable with other speedy calibers also the dial is marginally smaller in diameter
We are of course ignoring some redial that I have seen but they are mostly Type D1 with lume corrections
One final vital point ...all the service dials I have seen are coal Black Matt with crisp white writing .....originals are lighter and gray ...very noticable when posted side by side
Hence my earlier observation on another forum thread of the rareness of total original models and I believe Oddboy has an excellent reference prototype very authentic and externally looking totally correct which subject to his permission should be used as a comparative
