ND sub info please

[Mr. K]

Hello all, I should be getting my ND sub this next week.

Can someone tell me how long this Luminova version of the watch has been out? When did they switch from tritium dials to the current dial?

Any other changes to know about within the current model.

It seems like the ND sub has had few changes. The dial lume has changed and I think there was a movement change awhile back. But still has lug pin holes and a non SEL bracelet. Not even an upgrade on the bracelet extention.

Can someone tell me a little more history on my new purchase.To be honest, I thought I should pick it up before they start writing Chonometer on the dial.
