One is "less is more", that is, practical design to meet the needs of mass production, so as to minimize manual labor. Such as Seiko, ETA and other movement manufacturers, by streamlining their own movement structure, reduce the production cost and the difficulty of processing technology. The movement they produce is about several hundred dollars, which is also suitable for semi-commercial mid-range watches.
Another "always do better than needed" uses visually striking designs. This kind of movement needs less machining instead of a lot of skilled manual machining.
Take Amin Strom's independent movement as an example, it will adopt elaborate design and achieve excellent results through perfect surface treatment. Compared with mass-produced movements, independent watch movements need higher precision in design, processing, assembly and manual finishing.
In addition to making great efforts in mechanical design and operation, fine watchmaking also needs to reflect the wrist watch technology in aesthetics. Jewelry and advanced metal materials that match the movement, on the one hand, enhance the texture, on the other hand, represent more challenging processing.
