The Radiomir Black Seal is among Panerai's most affordable timepieces. Top models are made of ceramic and boast an impressive 8-day power reserve, which equals 192 hours.
The Italian luxury watch manufacturer Panerai introduced the Radiomir Black Seal in 2004. These models pay tribute to the Italian combat divers who used Panerai timepieces in the 1930s and 40s. During their night dives, they wore black wetsuits that made them look like seals, hence the "Black Seal" in this model's name. The term "Radiomir" comes from the radioactive luminous material of the same name, which Panerai used until the late 1940s. You can recognize a Black Seal watch by the "Black Seal" inscription on its dial. Earlier models had this inscription above the 6 o'clock position, while more recent models feature it below 12 o'clock.
The Radiomir Black Seal and Radiomir Base Logo are among the Radiomir collection's entry-level models. Top Black Seal models feature in-house calibers with an impressive 192-hour power reserve. This is the equivalent of eight days and is well above the power reserve found in most other mechanical timepieces. You can identify these models by the "8 Days" inscription at 6 o'clock. In terms of design, there's otherwise very little that distinguishes these timepieces from other Radiomir watches. They have a cushion-shaped case, conical crown, narrow wire loop lugs, and a smalls seconds dial at 9. There are also Arabic numerals at 3, 6, and 12 o'clock, with line indices marking the other hours.

The Radiomir Black Seal Logo is one of Panerai's most affordable timepieces. You can recognize these models by the Panerai logo at 6 o'clock. One example is the ref. PAM00380. This 45-mm timepiece is made of stainless steel and water-resistant to 100 m (10 bar, 328 ft), meaning it can accompany you on a swim. The manual caliber OP II powers this timepiece. This movement is based on the ETA 6497-2. It comes with a small seconds and 56-hour power reserve. A black calf leather strap holds this luxury watch securely on the wrist. The Radiomir Black Seal Logo ref. PAM 380 costs around 3,900 USD new and 3,800 USD pre-owned.
If you'd prefer a Black Seal Logo with an in-house caliber, you should take a closer look at the ref. PAM00754. It has the same design as the PAM 380, but is powered by the caliber P.6000. This movement features a small seconds and a 3-day power reserve. That is the equivalent of 72 hours, which is 16 hours longer than that of its sister model with a third-party caliber. The stainless steel PAM 754 is 45 mm in diameter and water-resistant to 100 m (10 bar, 328 ft). Prices for a never-worn piece come it at just over 3,800 USD. Pre-owned models sell for about 3,600 USD.
Thanks to its lack of a small seconds, the dial of the Radiomir Base Logo ref. PAM00753 looks particularly tidy and symmetrical. This version demands almost 3,500 USD new, while used watches change hands for under 3,300 USD.
Automatic watches have one distinct advantage: You don't have to wind them by hand every few days. This puts less stress on the crown and is convenient for the wearer. The Radiomir Black Seal 3 Days Automatic is one such timepiece. This model bears the reference number PAM00388. Like its manual counterparts, its stainless steel case is 45 mm in diameter and water-resistant to 100 m (10 bar, 328 ft).
Panerai equips this watch with the in-house caliber P.9000. This movement boasts a 3-day power reserve. You can view the P.9000 at work through a sapphire glass case back. A mint-condition Radiomir Black Seal 3 Days Automatic costs roughly 6,000 USD. You can save around 1,100 USD by purchasing a pre-owned timepiece.
The Radiomir Black Seal Ceramica is one of the highlights of the Black Seal series. It has a black ceramic case, which lends this timepiece its sporty and modern look. Ceramic has the added advantage of being much lighter, harder, and more scratch-resistant than stainless steel. However, this doesn't mean you have to sacrifice water resistance, as this watch can also handle depths to 100 m (10 bar, 328 ft). Panerai pairs this timepiece with a black leather strap, which coordinates perfectly with the rest of the watch. Luminous white hands and indices contrast beautifully with the otherwise solid black design.
The caliber OP XI, based on the ETA 6497, powers the three hands of the Black Seal Ceramica. This manual movement can run for a maximum of 56 hours before needing to be wound again. Plan to spend around 7,000 USD on a new ref. PAM00292. At 5,100 USD, pre-owned versions are quite a bit more affordable.
The Radiomir Composite Black Seal 3 Days Automatic is made of a brown ceramic-aluminum composite. This material is even lighter than ceramic and just as scratch-resistant. A brown leather strap, brown dial, and beige luminous material add to this timepiece's vintage look. The automatic in-house caliber P.9000 ticks away inside the high-tech watch. You can call a ref. PAM00505 your own for about 6,600 USD new and 5,700 USD pre-owned.
The top model in the Black Seal series is the Panerai Radiomir Black Seal 8 Days, ref. PAM00609. Thanks to the in-house caliber P.5000, this stainless steel watch has an astounding 192-hour power reserve. A sapphire glass case back offers a view of the manual movement at work.
The PAM 609 has a 45-mm polished stainless steel case. Like the other Black Seal models, it is water resistant to 100 m (10 bar, 328 ft). The Black Seal 8 Days costs around 4,900 USD in mint condition and 4,400 USD pre-owned. This makes it roughly 1,100 USD more expensive than the Black Seal Logo ref. PAM 754 with a 3-day power reserve.
