Introduced in 2020, the Panerai Luminor Marina TuttoGrigio reference PAM01662 has a titanium case with ‘Carbotech’ bezel, and a Grey diall. Inside ticks the self-winding caliber P.9010.

Nicknamed “The Ghost” and officially known as the Panerai Luminor Marina TuttoGrigio PAM01662, this model stands out – not because it draws attention, but because it deliberately blends into the background. What makes it unique is the way the case is built. Instead of being cut from a solid block, the titanium is 3D-printed layer by layer using a process called Direct Metal Laser Sintering (DMLS). This allows Panerai to shape the case with less material inside, making it lighter without losing strength. Paired with a Carbotech bezel and a muted grey color scheme, the result is a watch that looks and feels different from anything else in the brand’s lineup.
Released in 2020, this Luminor Marina was part of Panerai’s special series focused on new materials. It uses modern technology but keeps the classic Luminor look.
So, how did this all-grey Panerai come to be? Let’s look at how the brand used cutting-edge technology to bring the PAM01662 to life.
On-Wrist Feel
In 2020, Panerai introduced two special models called “Prima Assoluta” (meaning World Premieres) each one showcasing a new material for the first time. One of them was the Luminor Marina PAM01662, a stealthy grey watch that combined 3D-printed titanium with a Carbotech bezel. It wasn’t just a design update; it showed exactly what Panerai’s innovation lab, Laboratorio di Idee, was created for.
Laboratorio di Idee is Panerai’s internal research and development program, focused on pushing boundaries in material science and watchmaking techniques. It is the division responsible for bringing technologies like Carbotech, Fibratech, and DMLS into the Luminor lineup. The PAM01662 was one of the first Luminor Marina models to benefit from this forward-thinking approach.
This “TuttoGrigio” (Italian for “All Grey”) version introduced a muted, monochrome style with a lightweight case and modern finish. Even with the new look, it still keeps the familiar 44mm shape and crown guard that make a Luminor easy to spot.
With that context in place, let’s dive into what makes the case and strap of this watch stand out in everyday wear.
Case & Strap
Built with a 44mm case crafted from DMLS titanium, this model stands out for more than just its size. The case is formed through a 3D-printing process that stacks 30-micron layers of titanium powder, allowing internal cavities that cut weight without compromising durability. After printing, the surface is sandblasted, giving it a matte finish that feels smooth to the touch and looks noticeably different from standard titanium cases.
Complementing the case is a Carbotech bezel, made by compressing thin sheets of carbon fiber with a polymer at high heat. The result is a dark, layered texture with visible grain lines that vary slightly from piece to piece – no two bezels are exactly alike. Panerai also uses Carbotech on the crown and locking lever, giving high-wear areas extra durability and visual contrast.
The watch comes on a black Sportech strap, made from a water-resistant synthetic material that looks like sailcloth. It is lined with leather on the inside for added comfort and fastens with a trapezoid-shaped titanium buckle coated in DLC (Diamond-Like Carbon), a hard, matte finish that helps resist scratches and wear.
After covering the exterior, it’s time to look at the dial, which follows the same all-grey theme and keeps legibility and function at the core.
Dial Design
The dial of the PAM01662 continues the monochromatic theme with an anthracite grey finish and matching grey Super-LumiNova. True to Panerai form, it uses a sandwich structure: numerals and indices are cut out from the top layer, revealing the luminescent material below.
The layout is familiar – small seconds at 9 o’clock and date at 3 o’clock – ensuring easy orientation while keeping things symmetrical. Even the brand name, model designation, and running seconds subdial is printed in subdued grey tones, reinforcing the stealthy aesthetic.
Despite the muted color palette, legibility remains solid in well-lit conditions, and the grey lume emits a soft glow in the dark. It is not as bright as traditional green or blue lume, but it complements the theme without compromising functionality.
Now that we’ve covered how the watch looks, let’s take a look at what’s ticking inside.
Movement & Functionality
Powering the PAM01662 is Panerai’s in-house Caliber P.9010 automatic movement. It runs at 28,800 vibrations per hour (vph), which helps keep the timekeeping smooth and accurate, and offers a 72-hour (3-day) power reserve, stored across two barrels. The movement is just 6mm thick, helping keep the case profile relatively slim for its size.
This caliber includes a quick-set hour hand that moves independently, making it easy to update the local time or change the date without stopping the watch. The current P.9010 movement does not stop the seconds hand when the crown is pulled – making precision time-setting less exact than before.
While it operates through Panerai’s signature crown-locking system rather than a standard screw-down crown, the winding and setting actions feel smooth and responsive. The bi-directional rotor keeps the watch charged efficiently through daily wear.
Panerai pairs this with a solid titanium caseback and a 300-meter water resistance rating, making it more than capable of handling water activities or everyday conditions.
But specs aside, what does it actually feel like to wear?
On-Wrist Feel
Despite its 44mm case size, the PAM01662 wears lighter than expected. Thanks to the hollowed DMLS titanium construction and lightweight Carbotech components, it doesn’t carry the same wrist heft you’d get from a full stainless steel or bronze Luminor.
The lug-to-lug distance of about 53.8mm gives it some wrist presence, but the short, curved lugs help it hug the wrist rather than hang over. The matte textures and darker color palette also give the illusion of a smaller watch, making it more wearable for medium-sized wrists.
The Sportech strap adds to the comfort factor. It is flexible, breathable, and contours well after a few wears. Paired with the DLC-coated titanium buckle, it keeps the watch secure without digging in.
If you’re familiar with Panerai’s bigger watches, this one feels lighter and easier to wear but still keeps the classic Luminor shape.

A Familiar Look with a New Feel
