Mordis,
I don't generally worry about it, but if you want to quantify the error in a particular model of sexatant with such a label, just go with the published number found in the sales brochure. The Astra IIIb, are around 20" of arc (0.3") and on the high end of metal sexants, while the assens & Plaths claim around 12" (0.2'). For most uses these are pretty neglible errors
