Omega 145.010 Chrono Stop Repair

Recently my apprentice James purchased his very first chronograph, an Omega Chrono stop Driver. reference 145.010, this watch is easily identifiable with the face turned 90 degree’s compared to normal. The motivation was to repair and store the movement and case back to original. Chronographs are tricky to learn but this chrono is easier due to the movement design and functions.

Omega 145.010 Geneve Driver

This watch was in a little worse for wear and wasn’t running. It had been polished and refinished incorrectly in the past. This watch has a radial sunburst brushed finished on top. next to this you have two high gloss polished surfaces. Where the issue arrives is in keeping the gloss and brushed surfaces separate. When the finishes cross over we often refer to this as creep.

One sign of a good polish is have distinct consistent lines between the different finishes.

James was able to complete a full service of the movement all on his own and identify the faults. Below are a couple of photos of the watch after polishing.
