Panerai has introduced the Submersible GMT PAM01495, a 47 mm titanium dive watch that combines a skeletonised in-house GMT calibre with 500 metres of water resistance.
It is an unusually technical expression of the Submersible line, using 3D-printed Grade 5 titanium, a matte blue ceramic bezel insert and an openworked movement designed to remain readable rather than merely exposed.
A 47 mm DMLS titanium case built for depth
The PAM01495 uses Direct Metal Laser Sintering to form its Grade 5 titanium case layer by layer, allowing Panerai to create hollow internal structures that reduce weight without abandoning the large 47 mm format.
Panerai says the construction makes the case roughly 25 percent lighter than a conventional titanium case, which matters on a watch this broad and purpose-built.
The sandblasted finish keeps the watch firmly in tool-watch territory, while the blue ceramic bezel insert adds scratch resistance and a sharper visual contrast against the grey titanium.
The signature crown-protecting bridge is also sandblasted titanium, preserving the familiar Submersible silhouette while securing the crown for deep-water use.
Skeletonised mechanics without sacrificing legibility
Rather than using a conventional dial, the PAM01495 places its applied hour markers on the rehaut, leaving the calibre visible while keeping the time display clear.
Panerai uses two lume colours to separate functions, with blue Super-LumiNova on the minute hand and bezel markers, and green lume on the remaining hands and indexes.
The orange GMT hand is the most assertive element on the front of the watch, chosen for visibility against both sea and sky and for its connection to marine signalling equipment.
The date at 3 o’clock is handled through Panerai’s patented polarised system, which keeps the date disc visually discreet across the open movement and reveals the numeral only through the aperture.
The P.4001/S calibre carries the technical argument
Inside is the Panerai P.4001/S, a skeletonised automatic movement made from 341 components and developed with two patents.
The calibre runs at 28,800 vibrations per hour and stores 72 hours of power through twin barrels, giving the watch a practical three-day reserve.
An off-centred tungsten micro-rotor winds bidirectionally and sits level with the bridges, helping preserve the movement’s slimness while leaving more of the skeletonised structure visible.
The specification also includes a Glucydur balance, a KIF Parechoc anti-shock system and a free-sprung regulating organ.
Panerai has moved the power reserve indication to the back of the watch, where it is displayed through a sapphire circular indicator instead of crowding the open dial side.
The movement also includes a seconds reset function, allowing the seconds hand to return to zero when the crown is pulled for precise synchronisation.
500 metres, boutique-only availability and pricing
For a skeletonised watch, the PAM01495’s 50-bar water resistance is the detail that gives the project real substance.
Each watch is tested through vacuum checks, pressure immersion at 125 percent of its rated depth and a thermal moisture-detection procedure.
The Panerai Submersible GMT PAM01495 will be sold exclusively through Panerai boutiques from May 2026, priced at €49,000, £42,100 or $50,300.
It is delivered in a deluxe blue cherry wood box with a blue rubber strap fitted, a second black bi-material strap, a screwdriver for buckle changes and a sandblasted titanium trapezoidal buckle.
This is a watch for collectors who want Panerai at its most technical, not its most nostalgic, and who see the Submersible platform as a place where size, engineering and maritime function can still meet convincingly.
