Finally got my hands on a geiger counter, and it turns out this alarm clock is indeed spicy!
Radium was a common component for luminous paints in clock and watches back in the 30's, and plenty of those devices are still floating about today.

Really can't beat an ultrasonic for clearing out grime, neither pet hair nor tar buildup can stand it!
Lever set movements may be few and far between, but I love the way they are incorporated into case designs, needing to stick out enough to be easy to access and adjust, but hidden enough so as not to distract or interrupt the rest of the design.
A simple weight driven clock in a stand held over the end of a table, partially held down by a fake skull named steev.
Steev makes an excellent assistant, helping to hold the stand for the (fittingly) skeleton clock I've been working on this week.
A gold pocket watch case with 9 dots of blue puddy on it
I lovr working on old pocket watches, the history held within them is facinating.
Each spot of rodico on the case here is a different engraving from previous horologists who have servised this same watch at some point in the past.

Dream job right there!
oh that sounds frustrating! sometimes you just look at what work was done before and can't imagine what was going through the head of whoever last had their hands on it.
incredible!
Such a lovely movement!
This article is a series of letters exchanged in a horological newspaper column from 1866, transcribed by @allcollections.bsky.social . As different as the times were 160 years ago, it reads quite similar to modern internet argumentation, if in a bit of a longer format!

Figured i should show some of my work here, this one was an over 100 year old Junghans clock with some of the thickest brass plates i've ever gotten to work on, I hope to work on more like this beauty in the future!
First 5 minutes on the site and I find exactly the sort of thing I'd never see outside of social media, and it's right up my ally as a female horologist!
