• 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.

Iam having the cause of a problem with my waltham model 1892 the balance wheel seems to be bound up and will not turn freely . the balance staff and pivots but power does not seem to be getting transmitted to the balance from the mainspring. Any ideas on how to troubleshoot this problem? Thanks.

No telling what the problem is from here. That said, being that these are full-plate movements that sometimes give assemblers grief at the pallet-fork, I'll throw a broken pallet-fork pivot as one distinct possibility. Just a WAG though. I've seen this on a few 1892's. And to complicate matters, there are two or three different types of pallet arbors for the model based on pivot type, i.e. straight vs. conical. Only your watchmaker will know for sure. Unless you have decent knowledge of such things yourself, of course. Good luck.

for those who haven't seen the watch before I have a link which has pictures. This is a rather interesting watch as pointed out above it's a full plate but it's not your normal full plate. Unfortunately ilike all full plates everything is hidden. This makes troubleshooting definitely more interesting.

Be nice to have a little more background history like the watch was running perfect and this suddenly popped up. Then was was the last time this watch was serviced if ever?

The problem I have encountered with this movement, and I have several, is if the mainspring was replaced with an incorrect one, or one that is slightly taller than it should be. This will cause the MS barrel to sit high and therefore the plate will not seat correctly. I'm talking .01"-.015" of an inch. If this isn't caught, and the screws are tightened down, the resulting bind will cause the watch to not run. If you loosen the screws of that plate slightly and your watch starts running, you have solved the problem.
