• 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.

No. You might be thinking of the Atmos clock which runs on changes in temperature and pressure to wind the internal spring. You have what appears to be a standard 400-day clock. The suspension spring, if the proper one is chosen, will not be affected by temperature.

A moderator should probably move this over to the 400-day forum.

Well, 400-day clocks IMO are not the greatest time keepers. Gravity powered clocks are going to be better, but spring wound have a few "issues".

From what I've discovered, a full wind of the main spring will make the clock run fast, but that can be adjusted out. Once the spring has unwound a bit , the clock will run a bit slower, but again, it can be adjusted. To counteract this, it's suggested to wind the clock twice a year and to a 70-80% level...then it will be in the more constant power region of the main spring. They are one wind a year clocks, but ideally, twice year might make them perform better.

If you like the clocks, go for it. They can usually be had at reduced rates. From a repair standpoint, any excess friction will stop these clocks, so it's important to take care of that. And the escapement needs to be properly setup.

It would appear that the dome with the clock is not original...there seems to be too much "air" above the top of the clock and the dome. But I wouldn't let that get in the way of it...replacement domes can be purchased.
