Abstract: A regulating member for a horological movement includes an oscillating weight, for example a balance, a balance spring including a flexible strip wound about itself in a plurality of turns, the strip having a predefined rigidity to allow the oscillating weight to undergo a rotary oscillatory motion, and the strip including an outer end of the strip. The regulating member includes a resilient device for compensating for external pressure, connecting the outer end to a first support that is immobile with respect to the horological movement, the resilient compensation device being configured to adapt its stiffness according to the external pressure in order to compensate for an effect of the external pressure on the regulating member. Additionally, the horological movement includes the regulating member.
