Sorry for the late response. Usually, I'm Johnny-on-the-spot to comment on all things 1016.
I think it looks good, and I often recommend the Trusty 1016 to people asking for a good, out-of-the-box, vintage Explorer. I am puzzled by the dial, though, as that should be one of the Trusty's strengths. As sigsvoor said, this is a 5500 dial (and a pretty good 5500 dial, I might add), but it's wrong for the 1016. I would not recommend buying an NDT dial to replace it, but maybe you could contact Trusty about getting the correct SCOC dial for it? (I'm assuming that he really doesn't have any in stock, though.)
Alternatively, you could get an MBW 1016 dial that would work well. I may be able to help you with that, especially if you're 'Up North'. Drop me a PM.
I would not consider changing the crystal until I'm absolutely sure about the dimensions of the crystal/bezel on the rep. I am guessing that a Tropic 21 or 22 will not fit, but one member (If You See Kay) has had some success fitting a Tropic 19 onto his Trusty rep. It's a lot of work, but it will get you a taller and more correct-looking crystal profile. As for the hands, I would put them low on the priority list. If you really want a good replacement set, the hands for TC's Sub are probably the best.
I think Akira was referring to lugholes that will accept the fatter 1016 bars, which are as wide as Submariner springbars. Drilling the holes to 1.3mm would be a good mod, especially if you're thinking of reshaping the lugs.
