In the case below the rubber ring holding the movement is another nylon ring. This is not a gasket, as the seal is established between the case and the inner rubber ring. Note the two screws lying in the case – these are the screws that should hold the movement in the case ring, and they have come loose. No wonder the watch wasn’t working reliably…
And here is the case ring with outer rubber ring. This outer ring is pressed against the case and on the other side against the crystal, which provides the waterproofing. Unfortunately, AP doesn’t sell parts to independent watchmakers, so I will have to reuse the ring, rather than replacing it.
A beautiful movement indeed, and nicely decorated. The rotor has a 21 carat gold weight attached to it. As gold is very dense, you get a lot of weight per volume, which is important when making a thin movement.
With the rotor removed, you can see parts of the auto winder gears. The rotor engages with an intermediate wheel that sits in a ball bearing, which in turn drives a wig-wag wheel providing bidirectional winding.
With the barrel bridge removed, you can see the rest of the auto winder gears. The wheel with the 3 spoke “Isle of Man legs” construction on top provides a clutch that engages in one direction, and freewheels in the other. This allows manual winding without turning the oscillating weight.
With a new strap, the watch looks very nice indeed.
There is only one gripe I have with the watch. In my book, a watch should be able to make it for 100 years, so that it can go through at least 3 generations. A bit more doesn’t hurt. A rubber case ring will have degraded within 50 years or so, and at that time in the future, it’s unlikely that a replacement will be available, which will mean the end of the watch. I’d rather have something made from metal, and standard rubber seals that can easily be replaced, even 100 years down the line. My Rolex will have more of a chance to be worn by my great-grandchildren 😉
