The 2915 is lot 229
The PDF catalog is not the easiest to navigate.
Things to note/investigate, before buying.
1. Dial, does it react to a Geiger meter? all sorts of issues around that, because if the whole watch reacts, we have to ask is it from the plots, the hands or a little deceptive spot of radium placed by a wily watchmaker behind the dial. Still, you have to check. A zero reading tells you that its wrong, at least. A positive means that it could be OK but further investigation as to the source of the radiation should be made.
2. Bezel. We have to assume its a repro - it looks like it to me. Its a flat topped 3, no damage to the surface, no damage to the edges. Flat topped 3 types usually fell off shortly after production as they fitted poorly - so to see one on a watch is always rare, though they do exist. In addition this is a low serial so it probably had a flat 3 to begin with. I am still naive with these bezels, but it just doesn't smell right here.
3. Lume. The hands and plots match so perfectly that I would have to presume that one or both are adjusted.
4. Case back - unfortunately we don't see it, and we need to. The rest of the case has had some work, not surprisingly, and the case back might also have had work.
None of these things are a deal breaker, and to be honest the low estimate is a fair price in today's market. It is possible that if it is nice in hand, and the points I mention above are addressed, it could go more.
For example if the buyers become convinced the bezel is original, then I see it worth more. It may reveal more in hand.
2915's are really, really hard to value. The market is so thin, that if two collectors miss the sale it might not sell. By contrast, if two Rolex Daytona collectors sleep through the sale it will have no effect on the price.
I will watch this eagerly.
