Good question. I need reading glasses since I'm that age. I've not tried a lot of combinations but I've found that optivisor works well since you can wear glasses under them. I've mounted the extra magnification loup on my right eye when extra magnification is needed. If higher magnification still is needed, I use a standard Horotec loup in a head band without glasses.
The drawback is that the optivisor is somewhat bulky and sometimes tend to be in the way and you can "feel" that you wear it and after an hour or two you may need a break.
I never expect anything and haven't yet done a single Japanese watch (an Orient model EV0S004B with a calibre 46E40 is in the pipe), but I must say, PUSH being written on the movement seems very convenient.
For further clarification, Yes, it is exactly where it says “Push”, but also you have to pull out the winding stem to the first position, before there is anything to actually “Push” on. If you look into the space where you have to push, you will see the setting lever move into the correct place to be pushed, when the stem is pulled out to the first position.
