For dipping a toe into the (enjoyable) waters of Panerai, probably safest to start with something like a 111 or 005. You mentioned sandwich dials ('cut out' numbers) in your original post, so that would be models such as the 111, 112, etc. These models are popular and fairly easy to flip if you decide that the brand is not for you. They all use ETA-based movements, which will be easier to service than in-house movements.
Contrary to what you may read elsewhere, 'Base' models have two hands and 'Marina' models have three hands. There is a lot to learn with Panerai, not least of all the extensive model range. There is much fun to be had with straps and buckles, which for many is a big part of the ownership experience.
