"We’ve always used CNC machines,” explains Smith. “I’ve never shied away from showing that. If you want to make more than one watch a year you need to use CNC, there’s no question. Making pocket watches by hand is one thing but the reduced tolerances required for wristwatches is something else entirely. You make a change to one component and it affects five others. I’ve done it before but I don’t want to make watches that way.”
For Smith, the most important virtue of CNC manufacturing is “repeatable accuracy” and he estimates that 80 per cent of workshop hours are devoted to finishing components that have been “roughed out” using the CNC.
