FIELD: machine building.
SUBSTANCE: group of inventions relates to the field of machine building. First plate (1) made of the first material is taken. Second plate (3) made of second material is taken. Changes of the Young's modulus depending on the temperature have an opposite sign relative to changes in the Young's modulus depending on the temperature of the first material. First plate is connected to second plate to form substrate (2). Pattern (4) is etched in substrate to form composite compensating balance spring (31), including first thickness of first material and second thickness of second material. According to the second version, the method involves etching identical patterns in each of the plates. Connecting the first plate to the second plate to form a substrate. According to the third version, the method involves etching identical patterns in the rest part of the substrate to form a composite compensating balancing spring.
EFFECT: wider range of equipment is achieved.
