....not Yippy ?

Unfortunately, the style's popularity waned as the 1960s progressed and the concept of suburban conformity came under attack, yielding the idea of formal dress watches as link passe (that's French for "so last year!") by the younger generation. Dress watches, like many other trappings of middle- and upper-class American life, became symbols of the dreaded establishment, no longer desired by the link restless youthful link masses.

Starting with the ref. 6239 link in '63 the Daytona went through a period of incremental change and experimentation for the rest of the decade. It really wasn't until 1971 with the introduction of the ref. 6263 and 6265 that the model settled into a link groove and found its footing. These two references carry the Daytona all the way through 1988 until the release of link the "Zenith" generation. For manually-wound Daytonas the 6263 and 6265 are king.
