2 part question

[Coheed196]

So first off, brand new. Joined today, never have been a Rolex owner until a couple of weeks ago. Short version is, my grandmother passed away November last year. (98 yrs old) My sister and I have been going through boxes in her basement. I came across these 2 Rolex boxes. Looks to be 2 (his & hers sets). No paperwork, just the boxes and the little pillows. I know absolutely nothing about watches, let alone Rolex watches.

So questions are can anyone tell me what these watches are called? (I see Oyster Perpetual Date just) but not sure if there's more to it than that. Doesn't appear they've ever been worn, the watch bands and clasp part still have a shrink wrap type plastic around them. I'm sure they are old, aka vintage, as they were buried in a box in my grandmother's basement.

Second question you should have known was coming. Any ballpark figure on value? If can't answer the value part, I'd be glad to know what they're actually called.

Thank you
Vincent
