More Details


Our inspiration for the creation of this limited edition was the 100th anniversary of the death (May 4, 1919) of M. R. Stefanik (therefore the 100-piece limited edition), which we unfortunately failed to complete at the time of its anniversary. However, it also has its positive aspects, because in the meantime we have managed to improve a number of small details and bring this limited edition to perfection. In cooperation with the Slovak author of the book about M.R. Stefanik, Mr. Michal Ksinan, we also created three accompanying letters with a brief summary of the life of General M. R. Stefanik, which you will find attached to the watch. Please note that since this limited edition is offered mainly to our Slovakian customers, these letters are also available only in Slovak language.
