From the newbie on this forum.
Pay attention to these guys, they are steering you in the right direction.
I bought a kit very much like yours before I joined the forum.
It is a start and there are some good things in this kit but ....
You really need a good set of tweezers (take it from someone who tried these kit tweezers) and the heads on the screwdrivers didn't keep a straight edge, on mine the small set screw kept coming out, basically useless.
Once you try to put watch hands back on, you will see your tweezers will be worth their weight in gold !
I found most of the watch band tools to be good though, including the small pin removers (really useful for the stem and crown press release button on quartz watches), the only disappointment was the twisting blue device, the pins bend and buckle when you have a stiff pin in the watch band. Your better off with the small hammer, the small pin drivers (those in this kit located with the needle nose pliers and the plastic yellow block. Even the tightest watch band retaining pins don't resist a sharp blow with the small hammer.
As a kit, it is better suited for watch bands and the small parts of a watch.
Here's my assessment of the kit, I hope it helps !
