Watch Service: Breitling Superocean Heritage. Cal ETA 2824-2.

Glenn sent me his Breitling Superocean to service and opted for my light case refinishing option – the case brighten. I was actually quite surprised that I hadnt featured a watch with the ETA 2824-2 movement on this blog before, its a popular, bullet proof movement used in a range of brands.

Movement removed from the case, as always with any good divers watch, the dial is very legible. Although not often used as such, the watch is designed to tell the wearer how much oxygen is left in their tank whilst diving – being able to read the dial and particularly where the minute hand points to is a key part of this.

In order to use it as such, the bezels 12 o’clock point is aligned with the minute hand immediately prior to entering the water, the wearer then knows this is the start point. The amount of time spent underwater can then be calculated by checking the position of the minute hand in relation to this point.

An interesting fact as to why divers watch bezels will only ever turn anti-clockwise is because if the bezel happens to get accidentally knocked, it will indicate the diver has less oxygen in his tank and needs to return to the surface sooner. As opposed to it moving clockwise, and the diver thinking he has been underwater less time than he actually has, thus staying under longer than he should.

I remove the dial to reveal the 2824’s date, motion and keyless works.

I disassemble everything as far as the keyless works.

At this point I turn the movement over and begin work on the opposite side. In the picture below I have removed the automatic device.

After letting the power down from the movement, I begin to disassemble the components of the barrel bridge.

I continue on with the disassembly, first removing the barrel bridge, followed by the train bridge and gear train.

Once the watch is full disassembled I load it into the baskets in preparation for cleaning.

Once clean, the first components refitted are the shock settings for the balance, closely followed by the keyless works.

Barrel, Barrel bridge and train fitted back into place.

The movement is running at this point, I will oil the Jewels and escapement to the same specifications as the manufacturer would.

The watch is tested water resistant before moving onto its various mechanical tests.

One of those tests is the test for the automatic device, the watch is basically fitted to the arm of a piece of equipment that looks like a windmill, and the watch is slowly rotated. I do this from zero power to check that the automatic device is functioning as it should, and winds the watch up.

Finally, some shots of the completed watch after its case brighten. I do enjoy refinishing a Breitling, they are high shine and always come up looking very nice.
