To keep constant time, watches are fitted with balance whell made of

The balance wheel of a mechanical wriest watch has a frequency of oscillation given by f = ((1)/2pi) sqrt(C//I) , where I is the moment of inertia of the wheel and C is the torisonal rigidity of its spring. The wrist watch keeps accurate time at 25^(0)C , How many seconds would it gain a day at .-25^(0)C if the balance wheel made of aluminium ? (Given, alpha_(Al) = 25.5 xx 10^(-6//0)C)
