Tudor posted a short teaser on April 8, and within hours the forums had decoded, re-decoded, and then argued about every number flashed on screen. The brand turns 100 this year, the Watches and Wonders press days begin on April 14, and anything Tudor hints at in the week before the fair tends to land with extra weight.
The loudest theory is a revived Tudor Submariner. The quieter and more plausible one is a modern take on the Big Block chronograph.
What the teaser actually showed
Tudor's clip moved quickly and resisted easy screen-grabs. A few numbers were isolated enough to trigger speculation. Two Broke Watch Snobs wrote that the teaser "flashed a few numbers" that collectors almost immediately began connecting to "old reference points, historic dates, and deep-cut brand lore." No dial, no case shot, no price. Just the kind of hint that keeps a forum thread alive for a week.
The centenary backdrop is doing a lot of the work. Hans Wilsdorf registered the Montres Tudor trademark in 1926 through a Geneva intermediary, and the brand has spent the past decade rebuilding itself from a quiet Rolex offshoot into one of the most talked-about names in the accessible luxury segment. A hundredth birthday is the sort of moment a brand usually treats with a keepsake reference, not a quiet reissue.
The Submariner theory
Tudor stopped making the Submariner in the late 1990s, and the Black Bay line has done most of the heavy lifting for dive-watch nostalgia ever since. That is exactly why some collectors now think the teaser points back to it. The Black Bay is a modern reinterpretation. A real Submariner, with the name on the dial, would be a statement rather than a reinterpretation.
Others have pushed back on that reading. Monochrome Watches and Revolution both argued this year that the Black Bay already occupies the heritage-diver slot and the Pelagos holds the modern-tool slot, leaving little room to slot a third dive line in without cannibalising the first two. The counter-argument is that a limited centenary Submariner, produced in low numbers, would not need to fit into the permanent catalogue at all. Tudor has done anniversary pieces without building full collections around them.
The Big Block case
The other theory is less dramatic and, for that reason, probably more believable. 2026 is also 50 years since the original Tudor Oysterdate Big Block chronograph of 1976, one of the first self-winding chronographs in the Tudor catalogue. Kenissi, the Tudor-owned movement manufacture near Le Locle, has been developing in-house chronograph calibres for several years, and a prototype variant of the Big Block appeared in solid gold at the Only Watch charity auction in 2023.
A Kenissi-powered, in-house chronograph dressed as a vintage Big Block would fit Tudor's current pattern of quietly replacing ETA-based movements with its own. It would also give the brand a proper flagship complication to anchor a centenary year without forcing a revival of a discontinued collection.
What to watch on Monday
Tudor's stand at Watches and Wonders opens to press on April 14. A few things will answer most of the open questions quickly. If there is a new case shape, not just a Black Bay variant, the Submariner theorists were onto something. If the headline piece has a chronograph pusher profile, the Big Block camp wins. If it is a heavily finished, platinum-cased piece with Kenissi written on the rotor, the brand is making the argument that Tudor at 100 is no longer the low-cost cousin.
None of this has been confirmed. The teaser is a teaser. What is confirmed is that for a brand that spent most of its history in its big sister's shadow, the rest of the industry is now watching what Tudor does the week before Rolex even opens the curtain.
