Some registered Apple developers have received invitations for a "Special Opportunity for an Expedited Apple Watch Order." According to an invitation obtained by The Mac Observer, randomly selected developers can order a 42mm Apple Watch Sport (Silver with Blue Sport Band) with guaranteed shipping by April 28th.
Apple said the purpose of the offer is to give more developers a chance to test their Apple Watch apps as early as possible.

According to our developer sources, others who received this offer were all offered the same model Apple Watch. Speculation on the blue sport band being the least popular goes here.
