When Mr Silviu works one can hear only the clocks ticking. A song appreciated so much by the watch-menders.
If you happen to be in the shop at any sharp hour all sorts you will hear all sorts of clocks from all sorts of unusual places.
The workshop is very easy to find beacause is right on Calea Mosilor. At the entrance one can see written that this is also a workshop for jewlery but for now the jewler mender has paused his activity.
