Bands Without Sizes (One Size Fits Most) Ocean Band (Ultra), Sport Loop (Velcro), Nike Sport Loop (Velcro) - still need to select correct lug size.
Hermès In-Store Availability Generally Online Only or restricted to high-tier Flagship stores.
Action Button Programmable hardware key exclusive to Ultra 3 (Orange button) for instant workout start, flashlight, waypoints, etc.
SE 3 Double Tap Gesture Yes, supported because it uses the S10 SiP.
SE 3 Back Case Material Nylon Composite (plastic feel), not ceramic/glass like Series 11 and Ultra 3.
Upsell Argument: SE to Series 11 Sell Health and Visibility: Series 11 has ECG, 2000 nits (2x SE), and charges 33% faster (critical for sleep tracking).
Durability Argument: Series 11 vs Ultra 3 Ultra 3 is better for clumsy users; Series 11 has curved glass (vulnerable to doorframes), Ultra 3 has flat glass protected by a titanium lip.
Titanium Band Trick (Sales Scenario) Put an Ultra Trail Loop or Alpine Loop on a Series 11 (46mm); it fits perfectly and gives the rugged look for $99.
