Its amazing what the ongoing search for that "grail" watch sometimes turns up.
A Doxa - currently FS on ebay - http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=300837459500#ht_500wt_1414
turns out to be a bastard son of Breitling - http://breitlingsource.com/phpBB2/viewtopic.php?f=31&t=44307
AND to have a another Breitling 1/2 brother, with more cross breeding via Scubapro to Seiko!
To cap it off, all the little bastards had a quartz ticker!
Can only conclude that there were some high levels of watch incest back in the 70's and 80's.
That Breitling divers, which then traces through via Scubapro, to finally emerge as a Seiko, gives question to whether Seiko would have much claim to any patent action on that model.
Especially when it is understood that the basis of the case for Doxa was initially from Squale.
Lots and lots of "fathers" and "uncles", maybe even a freckled milkman came a courting?
Sometimes its not such a flash idea to go digging into the family tree! Never know what skeletons may be dug up!
Who wudda believed??
