This is a New York Standard, the grade name is New Era. It was an affordable watch when new (early 1900's), one step up from a dollar watch as it had jewelled balance. I think this New Era has a good example of the quality of a Perfection case from Philidelphia Case Co; these cases were plated and not gold filled. The outside is completely without any leftover gold plating, while the inside is still crisp. The dial was originally sold with these watches when new.
