Best of Watchville: Fratello Examines A Complicated Crystal

Prokop & Broz is a Czech watchmaker that, I have to confess, I’d never heard of before noticing a recent Fratello article on Watchville. A photograph of the watch in question, the company’s aptly named Spiral, had me wanting to know more. Clicking in, I learned about the intricate, months-long process that results in the Spiral’s sandwich crystal. 

Each one is made using  pieces of metalized glass that have been glued together and inclined at a 51-degree angle. It’s this angle of reflection, I learned from the article’s author, Tomas Rosputinsky, that allows for a secondary rainbow. You can see a colorful effect in the photo above. According to the story, Prokop and Broz have to make around 150 to 200 crystals in order to yield one  that is perfect enough to install in a final watch. 

I think it’s tempting to think of a watch’s movement as its sole center of complexity – and the cal. PB11 HS in this watch is definitely worth a look of its own. Nonetheless, I thought it was really neat to learn about a process for making an unusual watch crystal in an artisanal way.
