We present precise Sunyaev-Zeldovich (SZ) effect measurements in the direction of 62 nearby galaxy clusters (z < 0.5) detected at high signal-to-noise in the first Planck all-sky data set. The sample spans approximately a decade in total mass, 2 x 10(14) M-circle dot < M-500 < 2 x 10(15) M-circle dot, where M-500 is the mass corresponding to a total density contrast of 500. Combining these high quality Planck measurements with deep XMM-Newton X-ray data, we investigate the relations between D-A(2) Y-500, the integrated Compton parameter due to the SZ effect, and the X-ray-derived gas mass M-g,M-500, temperature T-X, luminosity L-X,L-500, SZ signal analogue Y-X,Y-500 = M-g,M-500 x T-X, and total mass M-500. After correction for the effect of selection bias on the scaling relations, we find results that are in excellent agreement with both X-ray predictions and recently-published ground-based data derived from smaller samples. The present data yield an exceptionally robust, high-quality local reference, and illustrate Planck's unique capabilities for all-sky statistical studies of galaxy clusters.
