Adjustable watch band having multi-part link units

An adjustable watch band comprising a plurality of link units, each of said link units having a first side and a second side, each of said sides facing in the longitudinal direction of the watch band, said first side having an engaging projection portion, said second side having a recess section, said recess section generally corresponding in shape to said engaging projection portion, adjacent said link units being connected by engaging said engaging projection portion to one of said link units with said recess section of another of said link units, wherein

• each of said link units includes a first link and a second link;
• each of said first and second links having a body, said body having an inner side and an outer side substantially parallel with the longitudinal axis of the band, a projection projecting from said inner side of said body in the lateral direction of the band and extending in the longitudinal direction of the band, and a notch portion formed by a base end side of said projection and said inner side of said body;
• said body having a blind hole formed in said inner side and extending in the lateral direction of the band;
• said projection having a through hole extending in the lateral direction of the band;
• said projection and said notch portion of said first link having shapes so as to form said engaging projection portion and said recess section of said link unit by adjoining with said projection and said notch portion of said second link;
• a connecting pin, said connecting pin having an inner end portion and an outer end portion, said inner end portion being engageable with said blind hole of said body of said first link, said connecting pin being slidably engaged with said through holes of said projections of said second link unit adjacent to said first link unit, and slidably and rotatably engaged with said blind hole of said second link of said first link unit so that said second link may be pivoted and slided on said connecting pin;
• and
• means for preventing said first and second links from moving in the lateral direction of the band when said first and second links are disposed substantially co-planarly, and for allowing movement of said links in the lateral direction of the band when said first and second links are relatively angularly displaced about said connecting pin.
