Brand Face-Off
Hamilton vs TAG Heuer: Which Is Better?
At the top the two brands meet in one band and TAG Heuer wins it: the Carrera Chronograph's in-house Calibre Heuer 02 runs 80 hours against the Hamilton Intra-Matic Auto Chronograph's Valjoux-based H-31 at 60 hours, both in the $2,500–$5,000 band. Below that band TAG Heuer has nothing in our catalogue and Hamilton has everything: the Khaki Field Mechanical (80-hour hand-wound H-50) in $500–$1,000 and the Khaki Aviation Pilot Auto (80-hour H-10) in $1,000–$1,500. Buy TAG Heuer if you are spending $2,500 or more; buy Hamilton for a Swiss mechanical under that.

Movements: in-house chronograph vs Swatch Group workhorses
The TAG Heuer Carrera Chronograph runs the Calibre Heuer 02, an in-house automatic chronograph at 28,800 vph (4 Hz) with 33 jewels and an 80-hour reserve. The TAG Heuer Aquaracer Professional 300 runs the Calibre 5, ETA 2824-2 or Sellita SW200 based, at 28,800 vph with a 38-hour reserve.
Hamilton's chronograph, the Intra-Matic Auto Chrono, runs the H-31, a Valjoux-based automatic at 28,800 vph with 27 jewels and a 60-hour reserve. Its field and pilot watches run the H-50 hand-wound (ETA 2801-2 base) and the H-10 automatic (ETA 2824-2 base), both at 21,600 vph with 80-hour reserves. The Hamilton Ventura is Swiss quartz. Hamilton's 80-hour reserve on a $500–$1,000 watch is the standout number in the table.
Build and water resistance
The Carrera Chronograph is 44mm steel and ceramic, sapphire, 100m (10 ATM). The Aquaracer Professional 300 is 43mm steel, AR sapphire, unidirectional bezel, 300m (30 ATM). The Intra-Matic Auto Chrono is 40mm steel with domed sapphire and 100m. The Khaki Field Mechanical is 38mm steel with sapphire and 50m (5 ATM); the Khaki Aviation Pilot Auto is 38mm with sapphire and 100m.
Hamilton's cases run smaller, 38mm to 40mm against TAG Heuer's 43mm to 44mm. For a true dive rating only the Aquaracer qualifies.
Price positioning
Hamilton spans three bands in our catalogue: $500–$1,000 (Khaki Field Mechanical, Ventura), $1,000–$1,500 (Khaki Aviation Pilot Auto) and $2,500–$5,000 (Intra-Matic Auto Chrono). Both TAG Heuer watches sit in $2,500–$5,000. The only head-to-head in the same band is chronograph against chronograph, where the Carrera's manufacture calibre and 20 extra hours of reserve are the case for TAG Heuer.
