Omega Seamaster cal 571 (2991-1-SC) - Looking for more info!

Hi guys,

Iv been a big fan of the vintage Seamaster watches for many years now and I was able to finally get my hands on this beauty a few days ago in an auction. It's a gold plated, 'boys size' Seamaster.

From the different online sources iv understood it was made sometimes late 50s or early 60s. Im not sure if the dial is original, it seems to be in very good condition if it is. The glass has the Omega logo. I feel as if the buckle is slightly off color, compared to the watch, so that might be non original. Thoughts?

I would love to know if anybody has more specific info on this watch! Grateful for any information or just your personal comments.

Thanks all!

Ref: 2991-1 SC
Cal: 571
Jewels: 24
Case size: Roughly 31.5 mm

Watch is actually gold capped. You have plated (over brass?), gold filled (thicker than plated over a brass case and applied under heat and pressure) and gold capped which is thicker than gold filled and bonded to a steel case.
