There are no arrows, no obvious pins, no pin latches. This band is different than all of the ones I've ever sized. Does anyone know how to remove links from this band?
Edit: user Septimaeus was correct in that it was a fixed link band. The link they provided helped in understanding what is requires to resize, and the band now fits my wrist like it was made for it. Thanks!!
It certainly has pins in the normal places. They must have been ground down after they were installed, making them extremely difficult to see.
If it was mine, I would grab each side of a link with a pair of pliers, and alternate between gently squeezing the sides together, and pulling them apart, with a very slight twisting action. I'm not trying to take it apart yet, just get enough movement in the pins to be able to identify them. Once found, remove like normal.
They may be extremely difficult to reinstall...
You could try some of the tricks used to expose the layers in Damascus steel: etching with various acids. The differing steels of the pins and the links may etch differently, revealing the pins.
Edit: at the time of this edit, not one other comment has even attempted to address OP's question. The only other suggestions have been to move the pin in the clasp (which is so bleedingly obvious that I can't believe that OP could have missed it; OP needs adjustment beyond the limits of the clasp) or to just buy a new band. (Again, bleedingly obvious).
What I described is certainly feasible for a patient and moderately skilled craftsman, and does not preclude the "advice" presented in other comments.
OP, consider hitting the pliers with an engraver while gently pulling. The vibrations may be enough to move it. If you're familiar with how metal reacts to a torch and can avoid overheating, a butane torch might help the pins begin to move.
Remember: you're only trying to find the pins. You'll need to punch them out.
You have no idea as to OP's level of skill, nor their motivation. They may be interested in attempting an uneconomical repair for sentimental reasons; they may be trying to determine the feasibility and just need to know what it will take. Or they may be trying to learn a skill they could apply to a more expensive band in the future.
Even if the pins break, they can still be drilled out and replaced entirely.
Another option would be to break off two links, and swap in a spare link from another strap which does have removable pins. Or pop out the link, and braze the ends together. Sure, they would be fused, but we do that with spines, and they remain reasonably functional.
As for your crimped pins; a slot cut across the band to the depth of the crimp would free the pin, and could be repaired with silver solder.
But, we never get to explore any of these options, because we didn't feel like engaging in any sort of craftsmanship, and skipped straight toward replacement.
