A book about the history of the mechanical clock. Its inventors, investors and consumers. I really enjoyed reading this. It’s like reading a history book but looking through a very specific lens. I like it as a concept and after reading this book I added a lot more ‘history of industry’ books to my list.
The mechanical clock
- Weight driven
- Transmitted energy of falling weight through a gear train
- Used oscillation to track the flow of time
1. Why Innovation Was Focused in Europe
- China
- Astronomical clock
- Water wheel clocks & clepsydras (sand timers with water)
- Froze in winter (same as in Europe)
- Middle East
- No trouble with cloudy skies or cold weather
- Hence sundials and water clocks worked fine —> No innovation
- Room for error
- Europeans brought clocks to China
- China did not take opportunity to copy and improve them
- China did not need to know the time like Europe did
- Communist china —> You do things when government says, not at a certain time
- Clocks represented an insult to china
- Clocks very Christian (telling you when to pray etc)
- Interest in time measurement —> The clock (Not the other way around)
- Popularity of clocks grew in line with developments in Astronomy
- Also grew as Christianity grew (prayer times)
- Monestary bells —> Timings for monks to increase productivity for God
- Early turret clocks
- Very expensive
- A mark of prestige
2. History of Horological Techniques
- Personalisation of time
- Miniturisation (1400s)
- Allowed for portability
- Birth of the watch
- Who’s watch was most accurate? <— Status symbol
- “Privatisation”/personalisation of time —> Individualism —> Growth of horology in Europe
- War
- Personal time was useful for military organisation
- Miniturisation (1400s)
- Regional Focuses
- Main parts of horology development
- English/Dutch: Greater accuracy & measurement precision
- Germans: Greater complexity (minaturisation, advanced engineering)
- French: Development of the watch as an ornament of beauty
- Drivers of accurate time measurement
- Astronomers
- Calculation of longitude at sea (longitude can be inferred from time differences at sea)
- “Dead reckoning”
- Britain announced big prize for whoever could solve this longitude problem
- Main parts of horology development
- Further Precision
- 1600s - Introduction of a minute hand
- Galileo vs Huygens: Who invented the pendulum clock?
- Industry ran into the verification problem
- How do you know if your watch is accurate if you dont have an accurate watch to compare it to?
- 1690s - Introduction of second and fractional second hands
- In Britain to ensure bookies knew the winner of Horse races
- Reaching an Asymptote
- The last gains are the hardest and this was the point the industry was at
- Improvements generally came in reduction of friction
- Using crystals/rubies in watches
- Adding oil regularly
- Longitude Problem Solved
- John Harrison
- Englishman that solved the longitude problem with a clock he made from wood
- His clock was called the H4
- John Harrison
- French rise to challenge English dominance
- Pierre Le Roy
- Arguably the greatest horologist to ever live
- Chronometer (detend) escapement
- Ferdinand Berthoud - Another french clockmaker
- Patriotism drove the french horologists
- Pierre Le Roy
- Arnold v Earnshaw
- In 1700s, John Arnold began to manufacture and industrialise the Chronometer
- Ran into competition from Thomas Earnshaw
- Large debate around the father of the English marine clock: Earnshaw vs Arnold
- A pocket chronometer by either of these men would still work perfectly today
- One Second = 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of ground state of the cesium-133 atom
3. Who Made Clocks, and How
- Royal comissions
- Something unique to clockmaking in the 1700s-1800s was that maintenance was as costly and time consuming as production
- “Royally comissioned”
- Watchmaking was expensive, so initially horologists were comissioned by royalty and the ultra wealthy to make custom pieces
- Division of labour
- Driven by specialisation
- Clockmaking broke down into
- Master clockmaker - Owner of the shop and maker of designs/manufacturing process
- Apprentices - Doing apprenticeship under a master
- Journeymen - Completed apprenticeship but had not yet opened their own shop
- Clockmakers guilds
- Made to protect against competition
- Had to be in the guild to sell clocks
- Prevention of competition = Decreased innovation
- British Superiority
- Britain vs France
- Industrial revolution
- British horology enjoyed a century of superiority in the 1700s
- Demand for watches in Britain grew as people had more money
- Initiation of import wars on watches from france
- Importing watches to copy them was a big market too
- Geneva
- Place of refuge for protestants in France
- Had a highly skilled population
- Had access to cheap labour in the farms of the mountains
- Travelling merchants grew in importance
- Knew what was popular
- Transported watches
- The Swiss Jura
- Abundance of cheap labour
- Low cost mass production
- Made very cheap watches
- Standardised parts —> Replaceable
- Geneva made the custom beautiful watches, the jura mass produced for the standard person
- UK unable to compete with the Swiss
- “Unification of time”
- As everyone needed to know the time —> Increased demand —> Benefits mass producers (Swiss Jura)
- Policy blockades preventing Jura watches in UK were avoided with smuggling, etc
- Growth of common time from: Railways, industrial work
- Growth of Swiss Industry
- Improvement of both quality and quantity from the Swiss
- New swiss watchmakers were popping up to make new styles (eg. Patek Phillipe)
- Swiss market too small —> Needed to export —> Made the industry more flexible to change
- American mass production
- Driven by civil war of 1850s
- Used machinery to make parts
- High production and great quality + accuracy
- US marketed their watches better than other nations
- Swiss Response to the US
- Swiss reacted to US much better than Britain did to the Swiss
- Swiss stressed the quality of their pieces, which were better than the US
- Marketed itself with a Swiss prestige
- After this the US industry fell away
- The Swiss became crazy dominant in the watch market
- Quartz Watches
- USA and Japan benefitted from this
- Timex, Seiko, Casio
- US did mass production right with Quartz watches
- Swiss lacked the technological ability to compete
- They stuck to the high quality, good prestige mechanical watches
- Quartz kept better time than a lot of more expensive watches
- Swiss lost a lot of market share as a result of not doing well with Quartz
- Swiss are still untouchable in the prestige market
- USA and Japan benefitted from this
