ETA 6498 Keyless work- Lubrication and fault finding

Now we were a bit more familiar with the 6498 we could start to learn how to service everything correctly. The movement minus the balance would be broken down into different areas. We would focus on one area at a time, learning how to find faults and how to correctly lubricate all the components. We […]

Initial Ideas for My School Watch- ETA 6498 Base Calibre

Long before the days of practicing for and completing examinations, I was already thinking about what I might do with the school watch we get to make. We will be using the ETA Unitas 6498 as the base, we receive the movement in kit form and each component has to be either made, finished or […]

Pivot Gauges with Straight and Conical Pivots

The second of our two micro mechanics exams was to produce a pivot gauge. We once again had a time limit of 8 hours to complete it, turned between centres using a hand lathe. The task would be a lot harder than the winding stems because this time we would be using blued steel, which […]
