We are here for you

We strive to do the impossible and so it was a matter of time before a watch with a water gun came along. It is a truly functional clock from the workshop of architect Ašot Haas, where the jet serves as an hour and minute pointer. Their trail is also fringed by a second scale with sixty small jets around the circuit of stainless body, which doesn’t defend itself from attention. It is also placed in the center of Florentinum arcade where it shows our creativity and unique attitude. A unique temptation is a sort of business card from an empire of precision mechanics; space-time, in which both women and men can live their dreams and feel pampered.

The services of watch store Koscom definitely aren’t limited to just the purchase. Of course, we are talking about our professional service from the hands of experienced master watchmakers, whose work you can personally witness in the store. The grounds of the store are really vast and our watchmaking services take place in our modern workshop which is divided only by a glass wall. This way, you can view the watchmakers working on your watches. Scratched glass, broken gadget or torn strap – we can solve almost everything. We have a certificate of authorized warranty service for 20 brands, but we are competent to take care of service after expiration of warranty or even cleaning your historical watches; family heirlooms.
