I know this won't help much -- but I DID have an order for the S6 44mm SBSS Noir single tour placed on 09/15 with "Arrives on Sept 21-23". On release day my order was STILL on "Processing" ... but my local Apple Store had the same watch available for same day pickup. So I canceled the 09/15 order and picked it up from the Store.
I don't know what your current status is -- but mine never moved past "Processing"; even with other Hermès orders with later Delivery dates at "Preparing to Ship".
Thank you for your reply. Mine is just in processing but it is still too early as it is not expected to ship until 9/30 or so. None of the apple stores around Los Angeles are open so I just have to wait. Apple is always slow to update their website for status so I just check my Apple Card balance and UPS or FedEx shipping by reference number. I was just hoping for an early delivery as i sold my series 5 and I miss it. Lol.
