Where can i buy Apple Watch Hermès Strap - 38mm Etoupe Swift Leather Single ?

Apple's online store is showing almost all 38mm Hermes straps are sold out in all regions. You might get lucky and find one in stock at one of the street Apple Stores, but If you have already checked Singapore and HongKong I think you are out of luck. You may have to wait until the next product announcement (September?) to find out if they are continuing the Hermes brand,

FYI the Apple announcements are now scheduled, Sept 12th.
