I've been learning in the watchmaking craft for some time and in my view, it's not about the cost of the lume itself that's expensive, but time to apply it and have a good finish on them. Sometimes you have to do several applications of the lume, sometimes you can just apply a thick lume, but the finish might vary. So I think it's the process itself that's quite expensive. For a smaller volume product, this process might not be a big problem or is something that the manufacturer is willing to pay, but if it's a high volume product, that slight addition in manufacturing time will add up. Just my 2 cents.

Hello, I'm still pretty new in the watch obsession game. Lately I've been really interested in dress watches, which then led me to various vintage watches. Would love to explore more with you guys here. Cheers!
