From War to the Auction Block: The Story of Sgt Rowson’s Panerai Kampfschwimmer

Watches, perhaps because they are so much more personal than almost any other artifact, have a knack of telling stories that bring the past vividly into the present. This is one of the best.

In the gathering darkness of the evening of September 28th 1944, a group of six German Kampfschwimmer (military frogmen) slipped into the Waal River in Holland and began swimming silently towards the road and rail bridges at Nijmegen. Their intention? To lay explosive charges under the main supports of the bridges—key strategic objectives on the way to Arnhem—and deny their use to the Allied forces. By 0600, they’d laid their charges under the bridges’ main supports and started navigating back to their lines. In another hour it would be daylight.

By 0630, they were confident they had made it back into German-held territory, and so they swam towards the riverbank. But instead of being greeted by their own side, they found themselves surfacing under the noses of Sgt George Rowson and his men of the 43rd (Wessex) Reconnaissance Regiment. They’d swum the wrong way.

Understandably, Sgt Rowson and his men were keen to ensure the next stop for the group of Kampfschwimmer was a prisoner of war camp, but only after (as was customary) they’d relieved them of their watches and any other spoils of war.

Rowson explained, “They were wearing these rubber suits and also each had a watch on one wrist and a compass on the other.” It’s likely the compasses that had led them astray were made by Panerai. The watches in question were the rather more reliable ref. 3646 diving models made by the same Italian manufacturer for the Decima Flottiglia MAS, the underwater unit of the Royal Italian Navy.


Before the Allies liberated the city in 1944, German forces raided Panerai’s Florence workshops, taking many of the watches. The diving models were shipped to Venice, close to the Italian Maggiore Wolk’s Kampfschwimmer training facility on San Giorgio in Alga before they were issued to individual divers.

And this one, in turn, found its way from the wrist of its nameless German owner to Sgt Rowson’s.

As an early Panerai, Sgt Rowson’s new watch was powered by a ref. 618 Rolex movement supplied by maker Cortebert. These were chunky, 16 ligne engines with 17 jewels and a beat rate of 18,000bph. Relaxed, but still accurate, reliable and eminently regulatable, they had micro-adjustment screws on the balance and a power reserve of around 36 hours. That’s all sufficient to still be ticking when you get captured because you’ve swum the wrong way, clearly.

The watch needed to be large (47mm) so it could be legible in low underwater visibility, hence the clear, cutaway and luminous-filled numerals on the dial. Where a modern watch would use phosphorescent LumiNova, this Panerai uses radioluminescent radium. Over time, the radium filling in the numerals has faded so as to be barely visible whereas the lume in the steel, blued hands is still much clearer and brighter.

Logically, the 12-sided case back and brevet-marked crown both screw down tightly to the case to make the watch waterproof.  These early ref. 3646 case backs seem to have hand-applied engine turning on the inside of the case back, but only around the circumference. They’re still stamped “Rolex,” unlike the later models where Rolex markings were removed. Sgt Rowson was clearly eager to ensure his new watch didn’t find another home by mistake. He carefully engraved the case back by hand with his full name, rank and the year he liberated the watch from its German owner.

Since leaving the bench, it’s been a well-traveled watch. Starting in Italy, the Panerai made its way (via the wrist of the unfortunate Kampfschwimmer) to Holland and thence to the UK and Nuneaton. After the war, Sgt Rowson passed the watch to his son who seems to have barely worn it.

Now the family is selling their WWII heirloom. Although, perhaps unsurprisingly, it doesn’t run anymore. It does, however, come with its original broad leather strap. Even more unusually, it also comes with a fragment of its original owner’s rubber diving suit.

One of the gnarliest straps you’ll ever see.

This isn’t the first ref. 3646 to turn up in interesting circumstances post-war, although it may be one of the most engagingly storied and best provenanced. In 2016, a Cheshire man found a ref. 3646 in a chest of drawers while he was clearing the contents of his late father’s house. He had no idea of its worth (his father had bought the watch at a car boot sale for £10 some years earlier) and casually strolled into a valuation day at a local saleroom with the watch in his pocket, thinking it might make as much as £500.

It sold for rather more. Apparently, post-sale, the auctioneer needed to explain to him exactly how much his father’s car boot £10 Pam had made. “When I told the vendor afterwards it sold for £46,000 he thought I had said ‘£4,000 to £6,000’ and had to repeat it three times before he believed me.”  Rather better luck than that of a certain Kampfschwimmer in 1944.

Birmingham-based auction house, Fellows, have put a rather conservative estimate of £30,000-£40,000 (roughly $41,600-$55,500 as of this writing) on Sgt Rowson’s watch. Given that there are few ref. 3646 models on the market and those there are carrying circa £70k prices, the hammer could easily fall somewhere north of £75,000 ($104,000). Sgt Rowson’s watch may not work any more, but the history it comes with is unique and the story it tells is priceless.

The watch will be auctioned on Tuesday, January 30, at Fellows Auctioneers in Birmingham as part of their January sale. To learn more about the watch and the other lots in the auction, visit Fellows.
