Edi Lüthi's workshop is in the centre of Bern's old town. He spends his time repairing wrist and pocket watches, regulators, as well as grandfather and alarm clocks.
Tuesday morning is market day in the capital, and the door to Lüthi's workshop opens every few minutes with a new customer. Not a good time to revise a complicated watch, a job requiring concentration and a steady hand. Changing batteries is more the order of the day.
It is unikely that anyone under the age of 30 would end up in the second-floor store. Most clients belong to a generation that has worn the same watch for decades and expect it to be fixed.
