Power Up with the Panerai Radiomir Black Seal

May 14, 2019

BY Celine Simon


To the untrained eye, most Panerai watches look so similar to each other that it can be challenging to figure out what the differences actually are. However, once you’re familiar with Panerai watches, you’ll note that each model brings something different to the table, while still retaining that bold Panerai aesthetic that has made the brand so famous. Today we’re taking a look at what the Panerai Radiomir Black Seal 8 Days has to offer.

The Design of the Panerai Radiomir Black Seal 8 Days

The Panerai Radiomir Black Seal 8 Days PAM609 sports a 45mm stainless steel case in the familiar Radiomir silhouette – cushion-case shape, wire lugs, no crown guards, and an oversized turnip-style winding crown. However, despite its large diameter, the PAM609 is relatively slim for Panerai standards, and sits comfortably on the wrist with a rather low profile.

As with most Panerai watches, the Radiomir Black Seal 8 Days houses a stark black dial with a mix of oversized and luminescent Arabic numerals and sticks. This particular version has a “sandwich dial” – a style of dial that is constructed in layers, where the bottom layer includes the luminous material and the top layer features cutout indices to display the luminescence below.

The PAM609 is what is referred to as a “Marina model” in Panerai parlance, which essentially means that there is a running seconds subdial at 9 o’clock. In contrast, the PAM609’s sibling reference, the PAM610 is a “base model,” which means that it only includes the hour and minute hands.

In case you’re wondering, the “Black Seal” label on the dial is a tribute to the Italian Royal Navy’s frogmen, also known as “Gamma Group.” Panerai has a rich history of supplying these elite combat divers with Panerai dive watches as early as the 1930s.

Completing the look of the Panerai Radiomir Black Seal 8 Days PAM609 is a beautiful brown leather strap, accented with white stitching. The strap tapers slightly to meet the large stainless steel tang buckle, which is engraved with the Panerai name.

The Panerai Radiomir Black Seal 8 Days Movement

Turn the Panerai Radiomir Black Seal 8 Days PAM609 watch around, and you’ll get a view of the manually-wound, in-house P.5000 movement operating  at 21,600 beats per hour, via the sapphire caseback. Introduced in 2013, the P.5000 movement utilizes two mainspring barrels to achieve an 8-day (192 hours) power reserve (as the name of the watch might suggest), which echoes the vintage Panerai dive watches that were made for the Italian Navy about 70 years ago.

Although the Radiomir Black Seal 8 Days PAM609 is considered an entry-level Panerai watch, you get plenty of value with this particular model. Along with the unmistakable Panerai aesthetic, you also get an in-house movement and a power reserve that lasts for more than a week. That all makes for a value proposition that’s hard to beat.
