Submariner above 12 O'clock dot

[salacak]

Anyone knows how to replace the green dot above 12 O'clock on submariner watches. I know they all different sizes and shapes and where can I purchase one what I need.
Thanks

If it's an older tritium you might try posting a WTB on varioue sales corners with the approiate reference listed. Rolex doesn't use trit anymore.

If it's a luminova dot, I've read someone with a parts account could get one, unless that's changed.
Might call the closest AD.
