Two-way communication makes the two instruments a perfectly complementary tandem in which each one is used for that which it does best. The EXOSPACE application allows the user to verify and adjust the main settings of the EXOSPACE B55 chronograph at a glance, but also to have rapid access to its different functions. The smartphone memory allows the different measurements of the EXOSPACE B55 chronograph to be saved so that they can be viewed, compared or even transferred to other applications.
