• 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.

When you say "Stops on occation" do you mean that it actually stops or are you assuming it is stopping because it is behind when you check time?

- It could be as simple as the hands slipping behind because of the low resistance you experience when setting the watch!

When you test it on a table do you check it in various positions i.e. Dial up and down and pendant up, down, left right?

- If it slows down or you have bad amplitude of the balance in one position, that may be a hint to what's wrong.

It definitely stops. I don't really notice bad amplitude in any particular position, but I looked at it under a microscope and it appears that the escapement wheel jewel could be worn because it looks like the pivot wobbles a bit in the jewel bore. Sorry, I'm not great with technical terms here. If it is that jewel, it will more than likely cost more that the watch is worth to have it professionally repaired.

The wobbeling and stopping could also be caused by a bent pivot. You need to have the balance removed and the jewels and pivots inspected.

The behavior is typical for a watch that has been dropped and often both the balanse pivot is bent and the jewel is damaged..... What talks against this is the fact that it keeps time in all positions....

Hi finiteguy,

The balance wheel is the one with the red circle, the escape wheel is the green one. As Skutt says, the pivots could be just worn if the watch is willing to run in all positions but occasionally stops. Although jewels can be cracked or otherwise damaged, they don't wear much in normal use, it's the steel pivots which suffer. However, he's quite right that it really needs inspecting properly. You're also quite right that the cost of any repairs would exceed its monetary value, but it would be a good learning opportunity for you if you're so inclined, to go through the diagnostic processes with guidance from here.

Regards,

Graham

Thanks for chipping in Graham,

I now realise that I read the post too quick and answered as if finiteguy was taking about the balance wheel even if he wrote escape wheel.....

Hi Skutt,

I wasn't sure which wheel he was meaning, so I thought we should be clear on some names to start with.

Regards,

Graham

Hi Skutt and Graham, thanks for your replies here and your help. I will take the watch apart again and inspect it. I will be retiring in a few months and it would be a great project for me....I will need to fill my spare time. I also found that the movement does not fit very tightly in the case...it rattles a bit because it's held by only one screw. I also noticed that when I removed the dial, there was no gold washer on the hour hand minute hand shaft. Could that also be an issue?

That is probably a brass washer called Dial Washer which function is to prevent the hour wheel from rising and disengaging from the pinion on the minute wheel. I don't think that will cause the watch to stop and the minute hand should basically do the same........
