• 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.

The speed adjustment is usually from the motor in electric clocks. In America, we use 60 cycle motors because that's how our electricity is supplied. If the clock comes from another country, it may not use a 60 cycle phase and will be inaccurate. That information is usually printed on the motor. If the motor matches the supply of current, and the clock won't keep time, it's likely because of excessive wear and/or dirt in the movement.

I understand. I'm not certain if this clock is actually run by a synchronous motor. If it is, that's as accurate as it'll get. If I can get a moderator to move this inquiry over to electric horology you'll likely get a more coherent response than I can give, but at the very worst you can likely install an AC movement like a Lanshire or whatever.

Edit: I just looked over at the electric horology forum and lo, there's lots of discussion about these clocks. Go have a look.

Thread moved for better exposure.
Thank you. Did I follow the correct procedure in "reporting" this thread? I worried that it would be assumed that something was offensive, somehow, but I didn't know how else to summon the authorities. (Although I could observe that standing on a ladder trying to figure out how the slave electronics on an IBM clock work is fairly horrible. It was many years ago and I thought I knew what I was doing and bragged about it, which is offensive in itself.)

Slave clocks won't run on their own, so yours is not that type. ;)

The only way to set this clock is to remove the glass and move the minute hand clockwise and the hour hand will follow or just wait until it is the correct time and plug it in. A signal generator or transmitter was required to correct this clock along with a master clock. Do you have a master clock ?

this type of slave will run just fine without a master. You may want to make sure that the correction mechanism is not misadjusted and dragging on the movement. There is a partial gear called a sector on the correction mechanism that should not touch the movement except during correction.
