This is my first post. I've been a long-time reader, and fan of the posts here.

I bought this Heuer Carrera at a local antiques market last weekend. The crystal has some deeper scratches, and I would like to replace it with the appropriate crystal, with period-correct profile. I've searched, but have not found a table of crystal makers or crystal numbers to use for replacement.

Could someone point me to such a resource or tell me what crystal to buy for this 3147?

Thanks!
