Round by Round Comparison
Round 1 — Design & Build Quality
🏆 Winner: Apple Watch Series 9 — iconic premium design
The Apple Watch Series 9 remains the most recognizable and premium looking smartwatch on the market. Its distinctive square design, available in aluminum and stainless steel, looks equally at home in a boardroom or a gym. The Samsung Galaxy Watch 6 has a sleek circular design that looks more like a traditional watch. The Xiaomi MI Watch S1 also uses a circular design with stainless steel case that looks surprisingly premium for its price point.
Round 2 — Health & Fitness Features
🏆 Winner: Apple Watch Series 9 — most comprehensive health platform
The Apple Watch Series 9 is the most advanced health monitoring device you can wear on your wrist. ECG, blood oxygen, crash detection, fall detection, cycle tracking and the new Double Tap gesture make it a genuinely life saving device. The Samsung Galaxy Watch 6 is impressive with its body composition analysis and advanced sleep tracking. The Xiaomi MI Watch S1 covers the basics well — heart rate, SpO2 and stress monitoring — but lacks ECG and advanced health features.
Round 3 — Performance & Software
🏆 Winner: Apple Watch Series 9 — watchOS is years ahead
The Apple Watch Series 9 powered by the S9 chip is the fastest smartwatch ever made. watchOS has thousands of apps, seamless iPhone integration and the smoothest user interface of any smartwatch. The Samsung Galaxy Watch 6 runs Wear OS 4 with Google apps including Google Maps, Google Pay and Google Assistant — very capable. The Xiaomi MI Watch S1 runs MIUI Watch which is functional but limited in third party app support.
Round 4 — Battery Life
🏆 Winner: Xiaomi MI Watch S1 — 12 days battery is unmatched
Battery life is where the Xiaomi MI Watch S1 absolutely dominates. Its incredible 12 day battery life means you charge it twice a month — you can even sleep with it for continuous health tracking without worrying about battery. The Samsung Galaxy Watch 6 lasts about 40 hours — you charge it every couple of days. The Apple Watch Series 9 needs daily charging at just 18 hours — its biggest weakness by far.
Round 5 — Display Quality
🏆 Winner: Apple Watch Series 9 — brightest display at 2000 nits
The Apple Watch Series 9 has the brightest smartwatch display ever at 2000 nits — perfectly readable in direct sunlight. The Always-On display shows time and complications without raising your wrist. The Samsung Galaxy Watch 6 Super AMOLED is vibrant and beautiful. The Xiaomi MI Watch S1 AMOLED display is good for its price but not as bright or sharp as the premium options.
Round 6 — Value for Money
🏆 Winner: Xiaomi MI Watch S1 — $150 cheaper than Samsung $250 cheaper than Apple
The Xiaomi MI Watch S1 at $149 offers extraordinary value — GPS, heart rate, blood oxygen, 12 day battery, AMOLED display and stainless steel build for less than half the price of the Samsung and a third of the Apple Watch price. The Samsung Galaxy Watch 6 at $299 offers excellent value with ECG and body composition. The Apple Watch at $399 is the most expensive but justifies it with the most complete health and software ecosystem.
