We love a vintage diver here at Falco, but every now and then, a piece comes through the door that’s just that little bit more special.
If you’re even remotely into Rolex and their four-digit Subs, you’ll likely know that their younger and pluckier sibling, Tudor, has also made some exceptional watches. While the 7928 wasn’t the first Tudor Submariner, it’s certainly the most revered and well known in the lineup—even though its eleven-year production run is relatively short in the grand scheme of things.
Initially, the 7928 came with a square crown-guard case like the Rolex 5512—only around 100 Tudors with this configuration were produced, and seeing one today is about as likely as bumping into a dodo. The Mk2 followed soon after, featuring the eagle-beak case; production numbers were slightly higher, but still only a few hundred exist. Then we arrive at the Mk3, which is the example on offer here: a pointed-crown-guard (PCG) case, a Swiss-only signed dial, and radium or early “glowy” tritium markers.
Most examples we’ve seen and tested haven’t shown radium past 1962 on a Geiger counter. The tritium on these does read slightly hotter than usual. One theory is that the Rolex Group anticipated the incoming crackdown on radium by 1960 and began adjusting their lume mixtures ahead of the regulations. This transition was well underway by the time the Mk4 appeared with the underline dial indicating the absence of radium.
This example, however, features a stunning full-radium dial. The watch is preserved in fantastic condition—the dial, visible beneath that dramatic super-domed glass, is mint. All the markers are intact and have aged to a rich pumpkin tone, often associated with radium. The hour and minute hands are the steel variant rather than gilt, but the large-bubble seconds hand is correct. The fat-font insert has developed a dark blue hue over time—subtle, but noticeable in strong light.
The case remains very strong and clearly hasn’t seen much polishing over the years. This is easy to spot on a PCG case, as polishing tends to soften or even erase the guards quickly. Here, both crown guards are still sharp and well defined, symmetrical around the no-dot crown.
The later C&I rivet bracelet, stamped 7/70, is in wonderful condition and retains all its links. The Fleurier 390 movement is running well at +3 seconds per day with 265 amplitude—one of the best-performing 390s we’ve seen.
As 7928s go, this is probably the nicest one we’ve had the pleasure of selling. In terms of rarity, these are far harder to find than their older brother, the 5512, yet they still sell for significantly less. Expect to see examples like this continue to rise in value as more are absorbed into collections worldwide.
