Apple Watch Bands 44–49mm — Series 4–11, SE & Ultra | Sport, Leather & Stainless Steel

Flip the watch over — the mm number is engraved on the caseback (44, 45, 46 or 49). Alternatively in the iPhone Watch app under “My Watch → General → About”. Series 4–6 + SE = 40/44mm, Series 7–9 = 41/45mm, Series 10–11 = 42/46mm, Ultra = 49 mm titanium.

Yes — Apple kept the pin system compatible. 44, 45 and 46 mm bands are interchangeable. They also fit mechanically on the Ultra (49 mm) but look tight — Ultra-specific bands (Trail/Alpine/Ocean) are the visually correct choice.

Three outdoor bands by Apple for the Watch Ultra (49 mm). Trail Loop: light nylon with Velcro for trail running. Alpine Loop: double-layer nylon with G-hook for climbing. Ocean Band: fluoroelastomer for diving, saltwater-resistant.

No — Apple Watch has its own magnetic charging pad. MagSafe is iPhone-only from iPhone 12. Both are magnetic but technically different systems — a MagSafe puck does NOT charge an Apple Watch. Ultra models charge via USB-C puck with Fast Charging (80 % in about 1 hour).
