This watch was purchased in 2012 and since receipt has never worked correctly. The main problem appears to be that when the watch is not upright (i.e. with dial facing upwards) it stops, thus losing time. The watch and all other received material (case, guarantee, etc) has been returned via post to the following address for repair: Thomas Bressous, Theorema, Gutenbergring 22, 22848 Norderstedt, Germany
