I have one or two scratches on the crystal of my 7T27-7A20. Is that something which can be recovered (e.g. Polywatch), or would it be a case of a new crystal? Wondering if this one is polishable or not?
They're quite minor and down at one edge so could easily live with, but....I do like my watches looking pristine! :-)
Most crystals can be polished - glass and sapphire can be polished with diamond paste.
Thanks. From what I read it seems like the crystal is 'Hardlex', would that be right? It sounds like polishing out might take quite a while to achieve!
It will be pretty difficult- maybe get a replacement crystalQuote:

More like nigh on impossible and a complete waste of effort, for the cost of a replacement crystal.
The original Seiko crystal p/n is obsolete and NLA, but there's the Sternkreuz substitute, p/n XMF320.927 - available from Cousins UK for £4.15 + VAT.

Thank you sir, exactly what I was after, much appreciated. Is that an easy fix(*) or is there anyone recommendable who is good with these Seiko models?Quote:

I've used cerium oxide glass polishing compound to good effect on Seiko's with hardlex though does take some time.
