The reach of the Apple Watch is due to expand both domestically and internationally in the coming weeks, reportedly arriving in Belgium on Sept. 19, and possibly U.S. carriers Sprint and T-Mobile later in the month.

The Belgian launch is official and will coincide with the opening of the country's first Apple Store, local site Apple Weetjes said on Thursday. Sport models will start at â¬419 ($475) and â¬469 ($531) in 38- and 42-millimeter sizes, respectively, while stainless steel Watches will begin at â¬669 ($758) and â¬719 ($814).

T-Mobile USA will begin selling the Watch on Sept. 25, the same day as the iPhone 6s and 6s Plus, according to MacRumors. The carrier's CEO, John Legere, recently confirmed plans for Watch sales, but did not offer a definite date.

Sprint will also begin sales on the 25th, according to stock screens from the carrier. Prices should be roughly identical to Apple's, though allegedly 99 cents higher. Unusually the carrier is expected to sell only third-party accessories by companies like Mophie and CaseMate, leaving out Apple bands.
