Magnification equipment for changing/sizing a bracelet

I'm in the process of trying to size a newly acquired 1125 bracelet for my late 60's Seamaster.
The bracelet just arrived yesterday and upon inspecting it, I realized that this bracelet uses screws, not pins. doh!

Using the 'fine' tip (1.2mm) of my Bergeon spring bar tool for width reference, it appears that a 1.2mm screwdriver blade will be a decent width to span the majority of the recess in the screw(s). So I'm going to place an order for a Bergeon 1.2mm screwdriver tomorrow. Before I close out the order and pay the shipping on something so small, I'd also like to get something to give me a little better visual fix on what I'm working on.

So my question for you guys is what do you use to magnify the work piece(s) when you're working on bracelets/links?

I'm debating between these two types of magnification aids:
Headband Magnifier w/ 4 different lenses (1.5, 2.0, 2.5, and 3.5 magnification), $24
or
Folding Magnifier (3x magnification), $10
or, I would also welcome suggestions on other contraptions to help me.

Pinky promise: that I won't go full gorilla on the screws and post another thread next week asking for help on what to do now that the screwheads are FUBAR'd. 😉 If the first one won't cooperate with light effort, I'll probably just tap out and take it to a watchmaker to have him remove them (along with the thin layer of dead skin cells and other crude that are currently residing in the screw holes. 😲

Just go to your local drug store/chemist and get a pair of 3+ reading spectacles.

I use them for general work and only use a loupe/microscope for detailed work like incabloc springs.tiny screws etc.

Great tip! I cruised over to my local drug store and picked up a set of +3.25 reading glasses, for $10. These should do the trick. 👍
