Apple Watch Series 12 46 mm GPS Black Aluminum with Black Sport Band

Wear a 46 mm GPS smartwatch in a black aluminum case with a Black Sport Band sized S/M. This Apple Watch Series 12 configuration combines the larger 46 mm case option with GPS connectivity, making the physical finish, case size, and supplied band selection clear for replacement or new-user requirements. The black aluminum exterior and black band create a consistent dark finish across the watch and wrist band. Apple MJEK4LS/A specifically denotes the Series 12 GPS version with the 46 mm black aluminum case and Black Sport Band in S/M sizing. Those details matter when matching an existing wearable standard: GPS connectivity is specified rather than another connectivity configuration, while the case is black aluminum rather than a different material or color. The S/M band designation also identifies the supplied Sport Band size. Use this configuration where a larger Apple Watch case is required with a black case-and-band appearance. It suits users replacing an identical Series 12 watch, standardizing personal devices with a 46 mm case, or selecting a GPS model with the stated band size. Confirm the wearer’s preferred case size and S/M band fit before selecting this exact configuration, since those are fixed attributes of the supplied watch and band combination.
