What would you pay for 170 Seiko new old stock Seiko Crystal?

That would depend on the crystal part numbers in the lot. 100's of nos Seiko crystals are useless to collectors when they don't fit collectable models.

With a comprehensive list of part numbers and some due diligence you could get an idea of what has actual value, calculate that and divide by two if you want to be generous, divided by four would be a "normal" lot price..

Im tempted all the time but tbh if you can't read serials its not really worth it. Or maybe youre ready to set up a store on ebay to resell all the ladies crystals and crystals to watches you have no interest in. Maybe lots of 80s quartz crystals? I'm mostly resigned to letting someone else go through that process, sell me what I need for a markup.

I’ve bought a few crystal lots in the past, but only when I can see that there are at least a few useful ones. It’s impossible to value a lot of crystals without photos/part numbers.

I would never pay that much for a crystal unless maybe if it was a rare 9 sided facet crystal that I need for a build or restoration. Today you can find replacements in almost any size for way cheaper and maybe even a better quality sapphire

I can say I agree with that. Seiko fabricated and installed many flat top domed underside and the only aftermarket you can find is from VTA, only recently and in one size. they aren't cheap either. otherwise sternkreuz are nicely made but often flat and they're "seiko" types are very limited. I have found that their acrylic rarely fit as they should either. Also, sapphire for vintage restoration doesn't make sense to me personally, but to each their own i suppose.

I agree sapphire for vintage restoration doesn't make sense but sometimes it's fun. It's like putting a brand new body kit on an old car.

I put a double dome sapphire on my July 1970 6119-6023 Baby Pogue because I had one in my parts bin marked for a 6105 and when I realized they take the same crystal I figured what the heck. It does not have ar and bugs me when I am trying to take pics of it I will eventually go back to a flat hardlex type 1 or 2 reproduction. But I may simply send the old crystal off to be polished.
