From a collector’s perspective, the Tritium dial versions (marked with the “T”) tend to be more sought after. The aging of the Tritium over time often develops a unique patina, giving each watch its own character, which many vintage enthusiasts appreciate. It adds to the watch's vintage appeal and originality.

That said, the non-Tritium (Luminova) dials are generally in better condition over the long term, since they don’t age the same way. If you're more focused on long-term wearability and clean lume, they might be preferable.

Given that you're planning to swap out the bracelet for a NATO strap and your primary love is for the dial itself, I’d lean towards the Tritium dial for its collectibility and charm — especially if you enjoy that bit of vintage flair.
