HSNY Member Exclusive: A Detailed Study of H4 (film)

We may not be able to meet in person lately but HSNY is working hard to continue offering exclusive benefits to our HSNY members. This month, we're happy to share "A Detailed Study of H4", a film about John Harrison’s successful Longitude timekeeper and its reconstruction project spearheaded by Derek Pratt.

Never before available in a digital version, this film is made accessible with kind permission from producer Barbara Darby, and is exclusively intended for members of the Horological Society of New York. (Use your HSNY member password to access.)
