About me

I was born on 08 April 1958, the son of a watchmaking family in Bad Langensalza. After school, I completed an apprenticeship as a computer and typewriter mechanic. After graduation, I began my training as a watchmaker and then acquired the championship title. Later, I took over my father's watchmaking company. There I deal with the sale of watches and jewelery and the repair of complicated watches. During my many years of work, I have gained a lot of experience. Some time ago, I relocated from Germany to Thailand and am now working for you in Chiang Mai, more precisely in the Doi Saket district. I have found that there is a large community of watch enthusiasts here in Chiang Mai who own quality Swiss watches and want them taken care of. I have had a number of Omega, Rolex, Patek Philippe, Jaeger LeCoultre, Roamer, Tag Heuer and so on watches repaired here. If you have a valuable watch that needs repair, please contact me. A high-quality mechanical watch would like to be cleaned and repaired by an experienced watchmaker after 5 to 8 years. Her precious, beloved watch is in good hands with me. Also visit my gallery. There I put together some repair reports and pictures.

Repair of an old tubular radio Nordmende Rigoletto from the year 1958

Although I am a watchmaker, I gladly accepted the order to repair this tube radio.

This vintage tube radio was outwardly in good condition, but the strong pollution no reception was possible, the tubes had no contact with the rest of the circuit. The power switch was gone and replaced with a cord switch. First, the radio was cleaned and all contact points were put back in order. So that the radio can be switched on and off again, I have decided to use a micro switch. I made a board and modified the micro-switch so that it could be placed in the original position. Please also note the pictures. Peter Hertel Chiang Mai, 2019 in May.
