I鈥檇 keep it original. If you don鈥檛 care for it, maybe sell it and look for another speedmaster in the condition you want. It is getting harder to find honest, original speedmasters. It seems they鈥檝e all had some part replaced or been polished or had their case backs scratched all to hell.
I actually like the look of this watch, what I can see of it, it looks like it has lived a life as a tool watch. Not in a drawer.
