I understand there are several dial variants to this venerable diver: Type 1 tritium Type 2 tritium Type 3a tritium Type 3b tritium service dial Type 3b luminova service dial Now as far as value is concerned...with all things being equal, would it be fair to say the order goes from bottom to top of the list in order of increasing value? Is there a sizable difference in value between Type 3a dial vs 3b tritium service dial? I assume there's definitely a relatively sizable value difference between a Type 3b tritium vs lumina service dial.
