Velociphile - No longer in the building

...No time now forgive me. I hope to return to this soon.
In a nutshell, bigger allows more room for more energy storage (spring), larger heavier balance wheel etc. If this energy advantage is released over a normal duration (e.g. 50h) through a higher inertia and/or higher frequency balance rather than simply to give a watch a long endurance (e.g. 8d) then this usually results in a watch with better stability of rate. Unfortunately, movement sizes have not generally kept pace with the space available in the current crop of big pieces (>42mm for example ;-)) to take advantage of this.

Bigger is better

As Velocophile says, bigger means more space for larger main springs and bigger balances. Bigger balance means more inertia which means more immunity to shock and more stability of oscillation (higher Q). Locking/unlocking forces can be higher which also ...
Only part of the story

I suspect that inertia is only part of the story. It gives you a lot of advantages in a watch that will be shaken and stirred, but there are other factors that come from having a physically larger movement to play with. In precisions clocks, one of the ke...
smaller and faster

with regards to the beat rate will even it out and make the accuracy of the movement less prone to being influenced by spontaneous shocks and wrist movements. That much being said, I love large balances and a slower rate of 18,000 to 21,600 bps because I ...
