‘70s Lady Date Question

[Heather B]

Greetings,

Please pardon any breeches of etiquette, as I am new to this forum.

My question regards a (presumably) 1971 Date Lady Stainless, Jubilee Band. (Serial No. starts with 342.) From the best of my estimation, the dial is silver (composite) with gold “numerals” (indices?), and I believe the bezel to be white gold. Though I will admit that much of this information is anecdotal, and I am no expert. Is there a standardized reference number for such a watch, that I might be able to refer to in my research, and do the material I’ve mentioned sound consistent with Rolex’s manufacturing techniques of the time?

Many thanks to the aficionados out t by ere — any info is valued. Pic is attached.
