I lost track of the number of times I needed help with repairs on old Hamilton wristwatches. For ten years, I searched for service manuals and had no luck. I expected a handbook and now I know that the company never printed one. Instead, Hamilton issued service bulletins, known as Technical Bulletin.
In 2011, I moved to Paris, TX to attend watch school at the Texas Institute of Jewelry and Horology. Unfortunately, Department regulations prohibited any variance from existing curriculum, and Hamilton movements did not exist in the syllabus.
I have yet to find all the Technical Data Bulletins Hamilton published. I did find most of the TD’s and included them in the PDF below. I haven’t found TD105 or TD106, yet. If I do find them, I will add them as soon as possible and update this page.
Please feel free to download the 46+ page PDF at this link: Hamilton Technical Data (Bulletins).
The download is free.
Enjoy!
