• Important Executive Director Announcement from the NAWCC

    The NAWCC Board of Directors is pleased to announce that Mr. Rory McEvoy has been named Executive Director of the NAWCC. Rory is an internationally renowned horological scholar and comes to the NAWCC with strong credentials that solidly align with our education, fundraising, and membership growth objectives. He has a postgraduate degree in the conservation and restoration of antique clocks from West Dean College, and throughout his career, he has had the opportunity to handle some of the world’s most important horological artifacts, including longitude timekeepers by Harrison, Kendall, and Mudge.

    Rory formerly worked as Curator of Horology at the Royal Observatory, Greenwich, where his role included day-to-day management of research and digitization projects, writing, public speaking, conservation, convening conferences, exhibition work, and development of acquisition/disposal and collection care policies. In addition, he has worked as a horological specialist at Bonhams in London, where he cataloged and handled many rare timepieces and built important relationships with collectors, buyers, and sellers. Most recently, Rory has used his talents to share his love of horology at the university level by teaching horological theory, history, and the practical repair and making of clocks and watches at Birmingham City University.

    Rory is a British citizen and currently resides in the UK. Pre-COVID-19, Rory and his wife, Kaai, visited HQ in Columbia, Pennsylvania, where they met with staff, spent time in the Museum and Library & Research Center, and toured the area. Rory and Kaai will be relocating to the area as soon as the immigration challenges and travel restrictions due to COVID-19 permit.

    Some of you may already be familiar with Rory as he is also a well-known author and lecturer. His recent publications include the book Harrison Decoded: Towards a Perfect Pendulum Clock, which he edited with Jonathan Betts, and the article “George Graham and the Orrery” in the journal Nuncius.

    Until Rory’s relocation to the United States is complete, he will be working closely with an on-boarding team assembled by the NAWCC Board of Directors to introduce him to the opportunities and challenges before us and to ensure a smooth transition. Rory will be participating in strategic and financial planning immediately, which will allow him to hit the ground running when he arrives in Columbia

    You can read more about Rory McEvoy and this exciting announcement in the upcoming March/April issue of the Watch & Clock Bulletin.

    Please join the entire Board and staff in welcoming Rory to the NAWCC community.

I collect US Military clocks, and have several IBM masters in my collection. Here's some pic's of both a US Navy and a US Army Air Forces model 35 IBM master clocks.
This is a Model 35 master clock that came out of one of the Naval Aircraft Factory buildings in the Philadelphia Navy Yard in the 1960's . It's pretty much a standard Model 35 with an Invar pendulum except the pendulum and weights were finished in Silver/Grey wrinkle paint. There's no power supply components or relays inside the case, the contacts are all wired to terminal strips on the top of the cabinet.

This is a US Army Air Forces Model 35 Master with a Mercurial pendulum. The only difference is that they overprinted the dial with red 13-24 numbers. I've seen 3 others like this with the standard cams and contacts to drive a slave system. What make this clock interesting is that this clock isn't actually a Master, It doesn't have any of the necessary contacts or cams. There are no holes in the case or any evidence of any wiring ever being installed. It appears that it was built as a very accurate wall clock. (The pic of the paper label on the back is from the Ebay ad when i bought the clock, I have the clock rated down to about 9 seconds /month so I don't want to take it down for a better picture)
