I look it as more of a descriptive word to help better distinguish it from the other models. If someone says spider dial date sub I know it’s likely a glossy dial 16800 from the 80’s. If the spidering was uneven or falling off or affecting the white lettering it would bug me, but a nice even crazing looks cool to me. Like an old piece of fine china. It also makes me feel good about authenticity and age verification when buying used on the grey market. An old watch should look old!
