Pi Day

by Jordan Ficklin

I guess it isn’t really watch related, and certainly not watchmaking related, but it is related to time. Besides being Einstein’s birthday, today is Pi day. And the minute this was posted was pi minute. There is even a pi second. To learn more about pi day check out the wikipedia article for pi day.

3.14 1:59 – or March 14th at 1:59AM represtents the first six digits of pi (3.14159), the constant which represents the ratio of the diameter of a circle to it’s circumfrence.

How should you celebrate?

You might try reading Life of Pi – which has nothing to do with the number or watches, but it is an interesting read.

Or . . . . . You could just post something on your blog, that’s what I’m doing. — Ok, I’m a math geek!

    Pi Day is interesting — but I was kind of surprised you didn’t blog about Abraham Lincoln’s watch. On Thursday, the Smithsonian discovered a hidden message under the dial of Abraham Lincoln’s watch, left by a watchmaker nearly 150 years ago. Did you read about that?

    Vince, I found the story about President Lincoln’s watch very interesting but was unable to get any new information to add. As I had already read about it on a half dozen watch blogs I assumed most of my readers already heard the story.

    That makes sense. I should have figured as much. As a professional watchmaker, what is your opinion of leaving a mark or “signature” inside a watch?

    I have thought about this topic a lot and I still don’t have a strong opinion either way. My training has always taught me to leave no traces in the watch, but even at Rolex they scribe the inside of the case back with repair details.

    I don’t see any harm in marking a case with a permanent marker (which isn’t really permanent) but I also don’t see much value in it.

    I have been waiting with baited breath for a year and a half for the AWCI Case Marking Committee to publish its conclusions on the subject.

    Certainly there should never be any marks left on a movement and if a case is marked it should be done professionally and as small as possible.
