Panerai Luminor Due 38 mm PAM00755

The storyWhy this reference matters

The Luminor Due was born in 2016 out of an awkward question: what does Panerai do about everyone who likes the design but cannot wear the watch. The answer was to slim the Luminor case down, give up on dive-grade water resistance and keep the silhouette. Same cushion, same lever bridge over the crown, roughly half the thickness. Purists called it a betrayal. Buyers, rather more of them, were grateful to get a hand back inside a shirt cuff.

At SIHH 2018 Panerai pushed the idea to its limit with the 38mm Due, launched as the smallest watch in its history. The PAM00755 is that version in steel with an anthracite grey sunray dial: 38mm across, 11.2mm tall, 20mm lugs, measurements that would be unremarkable at any other brand and that made news at this one. Inside, an in-house automatic with three days of running, small seconds at nine and a date at three.

The detail almost nobody mentions is that the PAM00755 did not always carry the same engine. The earliest pieces were marked with the OP XXXIV calibre and the later ones with the P.900, as WatchBase records: same watch, same reference, different naming. It was made between 2018 and 2020 in runs of 1,500 to 2,000 a year and is now discontinued, which makes it a quiet rarity from a brand not much given to quiet.

IdentificationHow to tell it apart

The first thing is the proportion, obvious once you know to look for it: the crown bridge takes up relatively far more of a 38mm Due than it does of a 44mm Luminor, and the case can look like it is mostly bridge. The lugs are 20mm, neither 22 nor 24. If a listing says 38mm Panerai and shows a 22mm strap, something in that description does not add up.

The PAM00755's dial is anthracite grey with a sunray finish, not black: in direct light the tone opens out from the centre towards the edge. Its twin is the PAM00903, identical in every respect but for an ivory dial. Small seconds at nine, date at three, baton hands. Nothing else on the dial, which is half the argument.

And the warning that always has to be made: 30 metres. The Luminor Due is not a water watch despite the crown bridge, which here works as a design quotation rather than a diving seal. Solid back, sapphire crystal, 11.2mm tall. It is a Panerai for a shirt cuff, not for a wetsuit, and buying one under the other impression ends badly.

CollectingWhat collectors check

Before you buy, ask about the calibre. Early PAM00755s carry the OP XXXIV, late ones the P.900. There is no meaningful difference in use, but there is when you ask for a service quote and when you compare two listings that look like the same watch and are not quite. The series letter on the certificate, U for 2018, V for 2019, W for 2020, settles which one you are looking at.

Those 11.2mm have an aesthetic consequence: the case is thin, the flanks are flat and every knock shows. Run raking light along the edges and the rim of the bezel. Look hard at the crown bridge too, which on the Due is smaller and more delicate than on a 44mm Luminor; a loose lever or a tired spring makes itself known the moment you open and close it twice.

Finally, the strap. The Due uses a quick-change system with 20mm lugs that taper to 18, convenient but specific: straps from a big Luminor will not do here. An example with its original strap and signed buckle is worth more than one on a generic band, simply because tracking down the right part costs time and money.
