Chasing a replacement crystal for this old Seiko 6309-4020

It appears the part number is ES8W48LM01 but I can't seem to locate a replacement anywhere. That's a lie, I found one on eBay (with no picture attached) for $100, but I'm gonna pass on that...

Does anyone have a good source?

Looks like this, but in worse condition:

Oh man, it's really about time I made a cousins account. Thanks @RichardHarris123!

Think I found a pusher for my casio amw707 on there too and a new crystal for it. Ooooh no, I'm gonna spend far too much on that site.

Half of my family are in Australia, they went as £10 poms.
