Hallmarks on a Patek Phillipe pocket watch

Hi,

A friend is trying to date a pocket watch he has bought, I have found the gold mark (750 Helvetica) for 18K and the Geneva mark (key with 2 crosses)

But there are 2 marks one which is both on the lid and the rim of the case around the face, which is an owl.

The other is a little obscured but is close the the owl on the rim, which looks like a hare running for left to right.

Sorry no good pictures I need to take some.

Do you have any ideas?

Thanks

Gary
