What do the credentials "FBHI" mean?

Answer: FBHI stands for "Fellow of the British Horological Instute". This is the British Horological Instute's highest grade of horologist and is realized through years of testing and advancement through several grade levels. Persons with this designation have proven to the BHI that they are dedicated to the advancement of horology and have above average skills at restoring historically important timepieces. For more information, contact the BHI. A note from a third party: Only a handful of people in the world have earned both CMC and FBHI levels of certification.
