Five automatic, in-house chronographs, none built on a third-party module — but each solves the same function (timing) with a different technical priority: proven reliability, high frequency, sport heritage, or integrated-bracelet design.
Calibre 4130, column wheel and vertical clutch, ~72h power reserve, fixed Cerachrom bezel with tachymetric scale. Zero date window, zero dial distractions. It's the chronograph every other one gets compared to, for better or worse.
Manual-winding Calibre 3861, Co-Axial escapement, METAS Master Chronometer certification. It's the only one of the five that isn't automatic — a deliberate choice preserving the original 'Moonwatch' tradition. Sapphire caseback on this specific execution.
El Primero 3600 caliber running at 36,000 vph (5 Hz), double most of its rivals here. It measures 1/10th of a second via a central hand that completes a full rotation every 10 seconds instead of 60 — the one capability on this list no other automatic chronograph matches out of the factory.
MT5813 caliber co-developed with Breitling (which builds it into its own B01), with a bidirectional bezel rather than the unidirectional norm on sport watches — it makes sense because its scale is a tachymeter, not a dive scale, so it can turn freely with no risk.
Calibre 2385 inside Gérald Genta's original 1972 Royal Oak architecture: an octagonal bezel with eight visible hexagonal screws and a bracelet integrated into the same case. It's the only one of the five built as a complete luxury sport piece, not a chronograph with a swappable strap.
Want the most recognizable market benchmark? The Daytona. Prefer manual winding with documented space heritage? The Speedmaster. Priority is timing speed and precision (1/10s)? The Chronomaster Sport. Want an unusual bidirectional bezel without giving up in-house manufacture? The Black Bay Chrono. Does the integrated bracelet and Genta's design matter more than anything else? The Royal Oak Chronograph. None of them have verified market price data in Cazador yet.
