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. 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.

American Pocket Watch Waltham Mass Repair and Service

I got this 17 stone American pocket watch from the brand Waltham Mass for repair. At first glance it looked like a normal repair. Clean the clockwork, set the gear, place the spiral, arrange the handwork and winding and finally adjust in 3 positions.

At second glance the errors came to light. A hole stone was broken and had to be replaced. It is not always easy to get a suitable perforated brick. After replacing the perforated stone, I found that the unrest in the position of the dial does not swing upwards sufficiently. This was remedied by polishing the journals of the balance shaft and all of the wheels. Later, when adjusting, there was a strong deviation in the position of the crown upwards. The position of the center of gravity, which must be removed, is then shown on the balance balance. Now the case was cleaned and the clockwork inserted. This pocket watch will now delight its owner again.
