I was just bumming around town, and came upon this 6106-8060 Sealion M110 from April '68:
The problem is, besides the imperfect crystal, is that it doesn't run. So that means a trip to the watchmaker. I've tried to find sale-price info for it online, and came up with a $150 sales price on SCWF a few years ago, to an as-is parts watch eBay sale of $15.
I'm thinking of selling it (but of course I couldn't pass it up), having just bought a black sawtooth, and sort of being at the mythical point of having "too many" watches...
