Design a custom pilot chronograph: a large legible case, bold Arabic numerals, syringe or sword hands, generous lume and a tri-compax subdial layout. Drag each subdial into place and the compatibility engine maps the count to a real caliber and estimates the case thickness.

What movement runs a tri-compax chronograph?
The automatic Valjoux 7750 is the classic choice for a 3-subdial (12·6·9) chronograph with a date.
How big should a pilot chronograph be?
Pilot watches wear large for legibility — 42–46 mm is typical. Timepiece Canvas lets you dial in the exact diameter and warns if a thick movement crowds a small case.
