Radio star: The incredible story of the Panerai diving watch almost lost to the sea

By: Alex Doak

In the nineties, you didn’t have Patagonia gilets, quarter-zip sweaters or Logan Roy logo-less baseball caps – you had ‘oversize’ watches. They were status symbols you could drive right into the boardroom, unlike your 911, and style statements to mark you out in a sea of suits. 

The sea is an appropriate metaphor, as the ur oversize timepiece started life sculling beneath Mediterranean waves, as anything but a statement timepiece. 

Long before the likes of Audemars Piguet’s Royal Oak Offshore swaggered onto the scene 30 years ago, Florentine engineering firm Officine Panerai was, in 1935, answering a request from the Royal Italian Navy: to create a waterproof watch for its covert frogmen, to keep them synchronised while sneaking up to enemy ships’ hulls and attaching limpet mines. 

It wasn’t just because of Giovanni Panerai and his technicians’ experience kitting out Italian warships with fuses, compasses and assorted military chandlery. He was the pioneer and patent holder of ‘Radiomir’ – a radium-based luminescent paint. It had proved itself (albeit in a riskily radioactive fashion) as a furtive solution to illuminating gun sights, and it would be perfect as a means of illuminating the hands and numerals of a diving watch during nocturnal missions. 

It worked a bit too well in fact – upon crossing enemy lines, aboard their two-man ‘torpedo’ mini-subs, the ‘incursori’ combat swimmers would have to cover their wrists with cloth to obscure the glow of their Radiomir watches: adapted from existing, cushion-shaped Rolex ‘Oyster’ pocket watches, with stencilled-out ‘sandwich’ dials retro-fitted atop fully luminescent base dials. 

All of which was totally unbeknownst until the nineties, when the Italian military secrets act expired and Panerai was revealed to be the watchmaker every alpha male should covet. Well, eventually… 

A few years before being snatched from obscurity by the Richemont Group and given its own purpose-built Swiss manufacturing facilities, Panerai was on the ropes. If it wasn’t for a Japanese watch magazine running a nostalgic cover story in 1992, new owner Dino Zei might never have been inspired to tentatively commercialise a strangely shaped diving watch discontinued in the seventies.

That watch was Signore Panerai’s ‘Luminor’ from two decades before, now with less-lethal tritium providing the glow, and fitted with a D-shaped crown guard. Zei ordered a run of 1,000, made in Switzerland. If it wasn’t for that tiny run, a well-connected Montenegrin photographer called Monty Shadow (bear with us, here) might then have never spotted one of those reissues in a Milanese shop window, then been so bold as to doorstep Panerai with the promise of brokering some white-hot product placement on the wrists of two Hollywood friends in their respective summer-of-’96 blockbusters, Daylight and Eraser. Arnie, Sly Stallone, Hugh Grant, Dwayne ‘The Rock’ Johnson, Jason Statham… 

With perhaps the exception of Mr Grant, it’s safe to say Officine Panerai became the watch of choice for a certain brand of hyper masculine gentleman. But once Richemont began evolving what was now an out-and-out watch brand, it would wisely return to its thirties origins beneath enemy waves: the (now-non-radioactive) Radiomir design, which, ironically enough by today’s sartorial standards, qualifies as an elegant dress option. 

That iconic cushion case contours to a slender, rounded-out square, with only the easy-to-grip conical crown and wire lugs interfering with an otherwise perfect, smooth ‘pebble’ of steel or gold.

It’s a delicate balance of lines and facets that, like every industrial icon, never dates and always bears revisiting. Bringing us to the latest ’Quaranta’ evolution, fittingly revealed during Milan Design Week, marking Panerai’s debut as partner to the 2023 edition of the ‘Salone del Mobile’. 

In the brand’s proprietary copper-infused ‘Goldtech’ alloy, the Radiomir Quaranta (£16,100) retains all those mid-century features, only with a small seconds and date added into the mix, and – as the nomenclature implies – pared down to a versatile, gender-neutral diameter of 40mm. 

White dials, blue dials, alligator straps, unisex proportions… it’s all a far cry from cigar-chomping A-listers at Planet Hollywood parties, let alone daring WWII saboteurs. 

That the Radiomir can legitimately remain true to its 87-year-old utilitarian form, however, says everything of good watchmaking’s ability to transcend time itself. It’ll always be back.
