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.

Audemars Piguet Royal Oak Offshore Replica Repair and Service

This replica Audemars Piguet Royal Oak Offshore Automatic watch is a few years old. Now the accuracy and duration of this watch decrease and a service of the movement becomes due. A Chinese replica of an ETA automatic with a decorative bridge is used as the movement. After opening the case, the movement is removed and dismantled into its individual parts. All parts are checked for defects and then cleaned. When putting it together, great attention is paid to cleanliness, the gear is checked and the spiral spring is re-positioned. Opening the shock protection is always critical. When the movement is working properly again, I will adjust it in 3 positions over several days and check the power reserve. Finally, I would like to say that the repair of an original watch is much more pleasant than the repair of a replica due to the very high quality. Replicants keep getting new errors or problems that are often not easy to master.
