Jerin,
An EXCELLENT "Doctor's watch" trio! You've become quite the collector and contributor here... in what, three+ months!? As have several other guys... Maybe I'll get back "involved" here, once I have the time and capital?
Yah... you have to BUY the crystals (and catalogs) when they surface... or GOOD LUCK finding them again soon, as it goes in waves, like anything/everything else on eBay and online!
If one only had 30 +/- Jewelers catalogs, THEN they could likely ID a couple hundred+ models, like the guys (eventually) did with Hamiltons... Or the same goes for an other brand/models, of course!
Find those catalogs... and increase interest and demand, 10 fold !?! (However I believe we got the stone rolling downhill, eh, with about a dozen +/- main contributors, here?!?)
Best :-) Scott
