• 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.

    Does this seem like a lot of oil?

    This video is not without problems. Here are few I've noticed: 1. Screwdrivers are undersized and slipping. This is sure way to damage screw heads and maybe something else. 2. Train jewels are literally flooded with oil. This amount is enough to lubricate five watches. 3. Escapement oiling is...

    English PW Watch repair hall of shame

    Here's one of my latest encounters with results of the shameful repair practice. The balance won't oscillate freely because the roller was askew. Inspection revealed that someone tried unsuccessfully tighten it on a balance staff. It was still kinda loose.

    How to get the proper mainspring

    Hello Samantha, how do you go about choosing a proper mainspring for a vintage watch if a catalog lists it in several strengths available for a particular caliber? One may be too weak for a good balance amplitude, while another is too strong and causes knocking.

    How to get the proper mainspring

    Hello Jftman, Dennison scale is different for width and strength. It's easier to think metric. Size 19-20 (width) on Dennison scale equals 2.8-2.9 mm. If Waltham catalog data for #2205 mainspring calls for 2.9-3.0 mm width then it's only 3% difference which is quite acceptable.

    Mechanical WW K&D 50 or 50B?

    Hello Sharukh Basically it's a high-speed DC micro motor with a Dremel-type grinding or cutoff disk and something to hold the balance staff - a drawbar with collet. A drawbar is brought forward for the bottom part of the staff to be ground off by the edge of abrasive disk until the remaining...

    Mechanical WW K&D 50 or 50B?

    Hello Lorne, By using the staff remover you'll eventually end up damaging the hole in the balance arm. The enlargement of the hole may be significant enough and the replacement staff will be loose or less evident and the balance wheel will require a lot of truing and re-poising. In the days when...

    Watch timing machines and hairspring vibrating tool questions

    It was indeed a very large hairspring. One can get an idea regarding its size when the spring is held by the fingers at 1:18. My guess it's about 20 mm in diameter. Handling the large spring is definitely much easier.

    Russian Translation?

    Hello Tim, as correctly noted by gatorcpa, the word to the left of "250" is indeed LASPOL in Cyrillic letters (ЛАСПОЛ). It is most likely that this custom dial design was made on order and the watch was then distributed among the members of the aforementioned chapter.

    Russian Translation?

    Hello Tim, the dial inscription means "250 years of the discovery of Russian America". Russian America was the common name for Alaska. This commemorates the date when the crew of Russian navigator Alexei Chirikov first landed on the Prince of Wales Island - July 15, 1741. LASPOL is the acronim...

    American PW Elgin Durapower Mainspring Questions

    You can check with the loupe if the hairspring is actually touching the balance arm, then check if the hairspring is horizontal and flat. For that you need to release the stud and remove the balance assembly. If you find that the spring is not flat and horizontal, it has to be corrected first...

    American PW Elgin Durapower Mainspring Questions

    Is your hairspring horizontal? Sometime the hairspring goes on top of the center wheel when the balance is installed. If this is what happened, just push it gently off the wheel. If it still rubs the wheel then the hairspring may not be horizontal and has to be corrected. Another possibility is...
