No rhyme or reason, ordered 2 Apple Watches (SS), 38 and 42 with w/black sports bands on 04/26. The 38 was received on 05-07, the 42 just changed today to: "delivers 22 June - 29 June". Not complaining just wanted to share my experience thus far. Demand obviously much higher than supply.
What kind of 42mm Watch did you get? I ordered the 42mm Space Grey with Black Sports Band on April 24th and have no delivery window other than "June".
