This Panerai Radiomir Black Seal 8 Days watch comes in a classic look. it is one of the most purest Panerai watches. The Panerai Radiomir Black Seal 8 Days PAM610 watch offers a lot of what you should be looking for in a timepiece from the popular brand.
This particular Radiomir case in steel showcases the “big watch” appeal of the brand, being 45mm wide, but is also surprisingly wearable with its thinner , roughly 12mm of thickness that helps it sit flatter on the wrist. Elegant as always, the Radiomir case in this instance is entirely polished with a domed sapphire crystal making for a dressier look in the scheme of Panerai’s catalog of vintage-style sport watches. If you need a Panerai to work with shorts or a suit, then the Panerai Radiomir Black Seal 8 Days PAM610 will actually work quite well. 
Many of the most beautiful, actually Panerai vintage watches have just two hands like the Radiomir Black Seal 8 Days Acciaio. We’ve seen a number of such watches come out in small quantities over the years – but often as very expensive limited editions, or as Panerai’s absolute entry-level watches that do not contain in-house movements.
Speaking of Luminor, if you are more of a fan of the Panerai Luminor case style of watches, then you can acquire an almost identical watch as the PAM610 in a Luminor version with the Panerai Luminor Base 8 Days Acciaio PAM00560. It has a very similar black dial, a 44mm-wide Luminor case.
The Radiomir edges out the Luminor case on sex appeal, and the sleek simplicity of the “lume sandwich” dial really helps complete the design package. Panerai could, however, make a few minor improvements such as considering use of additional AR coating on the crystal to reduce glare . I would also like to see a two-hand Panerai watch like this that has a power reserve indicator on the rear of the case . Especially with longer power reserve timepieces, I tend to universally find power reserve indicators very useful. They also prevent me from obsessively winding the crown all the time.
Seriously, for watch lovers like myself who always tend to wind a manually wound watch to its max, power reserve indicators help to prevent constant winding – which can help accuracy, as most watches are at their peak level of accuracy somewhere between being fully wound and fully unwound.
Speaking of winding, using the comfortable screw-down crown is a real pleasure on a watch like this. I also happen to like the quite large synthetic ruby palettes used in the movement which are visible through the transparent sapphire crystal caseback of the Panerai Radiomir Black Seal 8 Days PAM610. While Panerai Luminor watch cases are generally water resistant to 300 meters, the Radiomir case is water resistant to 100 meters . I would, however, suggest swapping out the super comfortable, supple and tapering, black calf leather strap if you are going to be in water much.
The wire loop-style lugs are removable from the case via two small screws, which allows you to swap out the strap for other ones – even though the strap design isn’t as universally replaceable as those for, say, Luminor-case watches that have more traditional lug mechanisms with straight bars.
