I’m absolute floored by the detail that’s went into this site about how Mechanical Watches work. It’s broken down into smaller, digestible pieces of information that uses interactive graphics. The site and interactive graphics all look to be hand built.
This isn’t the first time I’ve been in awe on Bartosz’s site. They’ve posted plenty of amazing interactive articles before. You should really go check it out. Some of my favourites include GPS and The Internal Combustion Engine.
You can view the rest of the articles at ciechanow.ski but be prepared to loose a few hours.
