In Biatec together with Czech seller Helveti, we are symbolically commemorating the 30th anniversary of the founding of the Czech and Slovak Republics and 30 years of mutual coexistence of the two young republics with a limited edition CS30 watch. The velvety divorce of Czechoslovakia, followed by three decades of fraternal coexistence, took place peacefully thanks to the linguistic and cultural proximity of the two nationalities and the enduring sense of belonging.
