The watch in question is PAM00422. It is a 47MM Luminor Marina 1950 polished stainless steel case. I dare say this model is maybe was a flagship model in their 1950 case series. It is a manual winding P.3001 in-house movement with a 72-hours power reserve but on a full wind, this particular watch of my will work for almost 80 hours.
I find this watch to a comfortable fit. IMO - you need a strap for a snug-fit. If you wear this watch loose, it will be top-heavy due to the sapphire crystal which is heavier than the plexiglass models.

I do not know what is the size of your wrist. Normally, for most people, their first entry level Panerai is a 44MM. As you noticed the gold-hands, I can think of only 2 models with gold-hands. PAM00390 and PAM00911. Both are special edition which are rather difficult to find now. However, 390 does not has sandwich dial.
Why not you let me or us know what would you prefer? Meantime, you should read more and do more homework.
