which bezel for the vintgage seamaster 300 is correct?

[If you see Kay]

I've seen two types of bezels, one with the yellow numbers as shown here:

and one that is only ss coloured, as shown in this example below:

which one is the correct bezel? or, are they both correct/

The top one has a more gen feel to it, but the dial is wrong.

Okay, so my watch is close in colour to the 2nd pic. Should I go ahead and color in the bezel markers yellow? Or should I leave it alone.

I've seen both examples on gens (Notwithstanding the first pic I showed, as that watch looks suspect in terms of its authenticity)

There's something like 4 or 5 different bezel insert types for the SM300. Regarding color, the safest bet is to have the insert numerals match the lume on the dial. However, there are examples of gens (with all-original parts) on which the lume doesn't match.
