Fantastic to see the time line. Even better to see some of the most iconic revolutions by british watchmakers.

Nicely organised table. Interesting to see that British time keepers invented a lot of things we currently use in watchmaking. Why is it that Switzerland has the monopoly of the watchmaking world?

Hi Alexis, that’s a question with a long answer! The short answer is that the Swiss were far better at adopting mass-production in watch manufacture. They also had invested so heavily in the industry that when the watch industry collapsed elsewhere in the world after the emergence of the electronic watch, they were stubbourn and persisted on. Most watch companies went bust and were bought up cheapily by conglomorates like Swatch or the Richemont Group. Then the mechanical watch came back into fashion and the industry started to grow again. By this stage is was only the Swiss left, so they were the monopoly by default.

Hello,
I’m just delving into the history and development of British horology as it relates to both clocks and watches, so as to forage forward into a path of my own in the watchmaking industry. I personally find it fascinating, especially when an inventor gets credit for their discoveries. It’s only fair, even if they never financially benefited from their discoveries. This list is extensive and I printed it out. Is this list of just only the inventors that are known whom are British? What about Scottish or Irish? I guess what I’m eluding to is that as it relates to the British Isles as a whole, is this list inclusive of ‘all’ the known British inventors and if so, what about Scotland, Ireland and maybe even Wales?

Hi Seph
Thanks for your comment. The list primarily focuses on British inventors, which includes all the nations of the British Isles, although the list will be heavily weighted towards the English, as historically they have had the larger population and the biggest influence on watchmaking.
