Help Identifying Features

[mfellers]

Hello,

Inherited my dad's OP, certificates from the purchase are dated early 1963, serial numbers has it ~1962. I believe the bracelet was replaced at some point over ~25 years ago. Serviced locally ~12 years ago and it was polished poorly and the crystal was replaced.

I'd appreciate help in identifying some features:
-What is this type of bezel style called?
-What is the dial color called, Champagne? Is there another naming convention for this color?
-Plan to add it to the insurance rider, any thoughts on a rough value?

Thanks in advance!
