Watch comparisons

Head-to-head comparisons that end in a decision rather than a shrug, with the trade-off stated plainly and the evidence laid out.

28 comparisons. Grouped by subject. Specifications from published sources, prices in US dollars.

Comparisons on this site end in a decision. Each one puts the options side by side, explains why the differences exist rather than just listing them, and then says who should buy which and why. Where the honest answer is that the difference does not matter, the page says that too.

What you will not find is a tie. If two things are close, the page names the tiebreaker.

Accuracy and standards

  • COSC vs METAS vs in-house accuracy standards

    COSC tests the bare movement to minus 4 and plus 6 seconds a day. METAS tests the finished watch to 0 to plus 5. Brands test their own. What each is worth.

Complications

  • GMT vs world timer watches

    A GMT tracks two or three zones with a 24-hour hand. A world timer shows all 24 at once. Which suits your travel, and why caller and traveler GMTs differ.

Fit and sizing

  • 38mm vs 40mm vs 42mm: which watch size

    Diameter is the least useful of the three size numbers. How lug-to-lug and thickness actually decide fit, with wrist sizes in millimeters and inches.

Materials

  • 316L vs 904L stainless steel

    904L carries more chromium, nickel and molybdenum than 316L, so it resists corrosion better and costs far more to machine. On a wrist, the gap is small.

Movements

  • Automatic vs manual winding

    A rotor buys convenience and costs thickness, weight and parts. A manual movement is thinner and more involving. How the two really differ in use.
