This Omega Seamaster Cosmic was a tough call.

The dial, hands, and the front of the case are in good condition but the back looks like it was used as a block plane.

During the inspection, it was immediately clear that it needed a service because the movement was very dirty. I also noticed that the sweep second pinion friction spring needed to be replaced because it was badly distorted. The crystal also needed to be replaced.

Based on the condition, the initial verdict was that this watch wasn’t worth the time and money. The owner would sell it as is.

However, it pains me to see a non-runner. Especially when it’s a watch like an Omega that would be a good runner with some love and one tiny new part. I decided to ask around for a used spring in good condition.

Luckily, I was able to find one so here we go.

This Omega 2416 came in a batch of watches to look at. It didn’t run, it was dirty and the crystal was in a terrible shape.

The movement is an Omega 28SC with an indirect sweep second. The concept wasn’t that successful as it had a few problems.

The second hand would often stutter as it’s not in the direct flow of power from the gear train. Also, it adds an extra layer to the movement, resulting in a thicker movement. It still lasted for 6 years, though. After the movement was relisted as the 370 they probably used it for another few years.

It’s possible to look up the serial number on the charts available on the internet. They tell you that this particular serial number is from 1943, however, several sources state that the 28SC is in production since 1944. It must be one of the very first ones then.
