Strengths & weaknesses
Strengths
- Column-wheel chronograph with vertical clutch
- COSC-certified with approximately 70-hour power reserve
- Breitling B01-derived architecture, not a Valjoux 7753 derivative
- One of the strongest technical arguments for Tudor Black Bay Chrono models
Weaknesses
- Not a fully Tudor-only in-house calibre; Breitling B01 collaboration must be explained honestly
- Chronograph service complexity reduces independent-service flexibility versus simple three-hand movements
- Must not be confused with Heritage Chrono 70330B modular ETA architecture
Why this movement matters
Power reserve
70 hours means you can take the watch off over a weekend and it will usually still be running Monday morning. That is a genuinely useful reserve for a daily wearer, not just a marketing rounding exercise.
Frequency
28,800 beats/hour / 4 Hz is a common modern automatic rate. Higher frequency can improve stability in some conditions, but service access and long-term ownership matter more than Hz alone.
Certification
COSC chronometer means the movement passed an independent timing standard before leaving the factory. That is useful, but it does not replace long-term ownership feedback or service network access.
Serviceability
Best handled through Tudor authorized service or qualified chronograph specialists. Avoid fixed service costs or intervals without source-backed data.
Movement origin
WatchIntel classifies this as Manufacture collaboration calibre. Origin labels matter because they affect service access, resale narrative and whether marketing language matches what is actually inside the case.
Finishing
Bridges and mainplate with alternate sand-blasted and polished surfaces and laser decorations. Finishing on tool-watch calibres is often practical rather than exhibition-grade. That is not automatically a flaw if the movement is robust and well regulated.

Medium confidenceMovement honesty
Public label: Manufacture collaboration calibre
A brand manufacture calibre built on a documented collaboration or shared architecture with another manufacture, such as Tudor MT5813 on Breitling B01. Not generic outsourced, but not fully isolated either.
Source nuance: Tudor officially calls MT5813 a Manufacture Chronograph Calibre. Independent sources identify it as based on Breitling B01 architecture and created through a Tudor-Breitling collaboration. It is not an off-the-shelf ETA/Sellita/Valjoux movement, but it should not be described as a fully isolated Tudor-only in-house calibre.
The Tudor MT5813 is a high-spec automatic chronograph movement used in the Black Bay Chrono family. WatchBase identifies Breitling B01 base architecture with 41 jewels, 33.80mm diameter and 28,800 vph frequency.
WatchIntel never overclaims "in-house" without source nuance. Manufacturer marketing language may differ.
