I doubt this will garner much interest but thought I'd submit it just in case.
What we have here is a basic 149 piece watch repair tool kit, sold and shipped by Amazon, which I purchased to hopefully use for changing the batteries in three or four watches, nothing too fancy more just for fun.
The shopping center shoe dude wanted $25 to change a watch battery last I checked but admittedly I haven't shopped around so might be cheaper elsewhere.
Hopefully the watch batteries themselves, whatever they are, aren't too expensive.
FYI - This has 108 Watch Pins which aren't really regarded as tools.
