We present a unique set of nested stellar kinematical maps of NGC 3377obtained with the integral-field spectrographs OASIS and SAURON. We thenconstruct general axisymmetric dynamical models for this galaxy, based on theSchwarzschild numerical orbit superposition technique applied to thesecomplementary measurements. We show how these two datasets constrain the massof the central massive object and the overall mass-to-light ratio of the galaxyby probing the inner and outer regions respectively. The simultaneous use ofboth datasets leads us to confirm the presence of a massive black hole with amass of $M_{BH} = 7_{-5}^{+4} 10^{7} M_\sun$ (99.7% confidence level), with abest-fit stellar mass-to-light ratio $\Upsilon_I = 2.1 \pm 0.2$ (for an assumededge-on inclination).
