FAQ
1. What can the three chronograph subdials measure?
The 3 o’clock subdial records up to 30 elapsed minutes, the 9 o’clock subdial records up to 12 elapsed hours, and the 6 o’clock subdial displays the continuously running seconds.
2. How is the tachymeter bezel used?
The tachymeter scale can estimate average speed over a known distance. Start the chronograph at the beginning of the measured distance and stop it at the end; the central chronograph hand points to the approximate speed on the bezel scale.
3. Why are the chronograph pushers screw-down?
The screw-down design helps prevent accidental operation and improves protection around the pusher openings. The pushers must be unscrewed before using the chronograph and securely tightened afterward.
4. Does the black dial look different under various lighting conditions?
Yes. Its glossy wet-look surface appears deep black in softer indoor lighting, while stronger light highlights the silver sunburst texture of the subdials and the polished central hands.
