Pre-orders for Apple's latest Watch have been open since October 8, 2021. The flagship wearable comes in a variety of case and band types, many of which began to exhibit shipping times dated November 2021 since their launch. In fact, one or two options are now completely unavailable for delivery.

Apple needs to work on their schedules. I bought a pro-max on last month's 20th and still waiting for it.
