In Context
At 44 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 300 m is a professional diving rating, far past any demand a wrist is likely to make of it.
The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 56 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.
PAM00033 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case.
Inside: Caliber OP II
Explore this caliber →The OP II is the hand-wound Unitas 6497 as Panerai fitted it to the Luminor Base and Luminor Marina through the 2000s. It powers 66 watches in this library, 65 of them 44 mm Luminors. The 6497 is a pocket-watch movement, 36.6 mm across, and the [Unitas piece](/blog/the-unitas-6497-and-panerai) explains why that suited Panerai: a 44 mm cushion case needs a large movement to fill it, and the historical Panerais had run pocket-watch calibers from Rolex and Angelus. The OP II runs at 21,600 vph with 17 jewels and a 56-hour reserve, with a small seconds at 9 o'clock and no date, decorated with Côtes de Genève. It is the least complicated movement Panerai has used and the one most watchmakers know best. In the library it sits under 65 [Luminor](/brands/panerai/luminor) references, the Luminor Marina boutique editions of the 2000s and 2010s, and one [Radiomir](/brands/panerai/radiomir). 47 of the 66 are limited editions, most of them boutique series of a few hundred pieces. The [OP I](/calibers/panerai-op-i) and [OP XI](/calibers/panerai-op-xi) are the other Unitas-based hand-wound movements in the range, and the [P.5000](/calibers/panerai-p-5000) is the in-house eight-day movement that replaced them in the Luminor Base and Marina.
65 other watches in the library run the Panerai OP II.
