Tudor's comeback over the past decade is one of the more interesting stories in watchmaking. The Black Bay — launched in 2012 as a heritage dive watch and now the brand's flagship — put Tudor back on collectors' maps in a way that decades of Oysterdate and Prince Oysterdate references hadn't. The Pelagos followed, becoming one of the most technically credible dive watches at its price point. The Black Bay Pro added a genuine in-house GMT function.
What makes Tudor particularly interesting from a winder perspective is its movement story. Starting around 2015, Tudor began introducing its own in-house manufacture calibers — the MT5000 series — to replace the ETA-based movements the brand had used for decades. That transition is ongoing, and it matters for winder settings.
Tudor's two movement generations and why they matter

If you bought a Tudor before approximately 2015, you likely have an ETA-based movement. If you bought one after, you may have a Tudor manufacture MT5xxx caliber. The two generations have the same winding direction (bidirectional) but different power reserve characteristics.
| Reference | Caliber | TPD | Direction | Power Reserve |
|---|---|---|---|---|
| Black Bay 58 (in-house) | MT5402 | 650–800 | Bidirectional | 70 hours |
| Black Bay 41 (in-house) | MT5602 | 650–800 | Bidirectional | 70 hours |
| Black Bay GMT Pro | MT5652 | 650–800 | Bidirectional | 70 hours |
| Black Bay Chrono | MT5813 (Breitling B01 base) | 650–800 | Bidirectional | 70 hours |
| Pelagos FXD (in-house) | MT5602 | 650–800 | Bidirectional | 70 hours |
| Ranger (in-house) | MT5402 | 650–800 | Bidirectional | 70 hours |
| Black Bay (older, ETA) | ETA 2824 | 650–800 | Bidirectional | 38 hours |
| Pelagos (older, ETA) | ETA 2824 | 650–800 | Bidirectional | 38 hours |
| Heritage Advisor (alarm) | ETA 2892 base | 650–800 | Bidirectional | 42 hours |
The 70-hour reserve on MT5xxx calibers is significant. Tudor engineered these movements to Rolex standards — the MT5602 is closely related to the Rolex Caliber 3132 — and the extended reserve reflects that investment. A Black Bay on an MT5602 can sit for nearly three days without stopping.
Older ETA-based Tudors carry 38 to 42-hour reserves. Two days and they stop. For collectors rotating through older Black Bay or Heritage references alongside newer MT5xxx pieces, a winder handles both with the same bidirectional setting — but the older references benefit more urgently from continuous winding.

The Tudor and Rolex collection
Tudor exists at the intersection of two collector types: the dedicated Tudor enthusiast who owns multiple references as a primary collection, and the Rolex collector who adds a Tudor as a more wearable daily driver alongside more precious pieces.
For the second type, the relevant fact is that Tudor MT5xxx calibers and Rolex 3235-based calibers share movement DNA and use identical winder settings — 650 to 800 TPD bidirectional. A multi-rotor system with both a Tudor Black Bay and a Rolex Submariner Date can run both slots on the same program without issue.

Frequently asked questions
What TPD for a Tudor Black Bay 58? 650 to 800 TPD, bidirectional. The MT5402 runs well at 700 TPD bidirectional.
Can I put a Tudor and a Rolex in the same winder? Yes. Both use bidirectional winding at 650 to 800 TPD. The same program covers both without compromise.
My older Tudor with an ETA movement stops after two days — is that right? Yes. The ETA 2824 carries a 38-hour power reserve. In-house MT5xxx calibers extend this to 70 hours.
Does the Black Bay GMT Pro need a different setting than the Black Bay 41? No. Both use Tudor MT5xxx manufacture calibers on the same bidirectional winding specification at 650 to 800 TPD.
