Mido vs TAG Heuer: Which Is Better?
On the spec sheet Mido wins the movement and TAG Heuer wins the depth: the Mido Ocean Star GMT runs an 80-hour Caliber 80 with a GMT hand and 200m water resistance in the $1,000–$1,500 band, while the TAG Heuer Aquaracer Professional 300 runs a 38-hour Calibre 5 rated 300m in the $2,500–$5,000 band, two bands higher. TAG Heuer's in-house case is the Carrera Chronograph, whose Calibre Heuer 02 is a manufacture chronograph with an 80-hour reserve. Buy Mido for reserve and value; buy TAG Heuer for the 300m rating or the in-house chronograph.

Movements: 80 hours vs 38 hours, and one manufacture chronograph
The Mido Ocean Star GMT runs the Caliber 80 on an ETA C07.661 base: 21,600 vph (3 Hz), 25 jewels, 80-hour power reserve, with a GMT hand and date. The Mido Multifort Powerwind Chronometer runs the Caliber 80 Si, COSC-certified with a silicon balance spring and the same 80 hours.
The TAG Heuer Aquaracer Professional 300 runs the Calibre 5 on an ETA 2824-2 or Sellita SW200 base at 28,800 vph (4 Hz), 25 jewels, 38-hour reserve. The TAG Heuer Carrera Chronograph runs the Calibre Heuer 02, an in-house automatic chronograph at 28,800 vph with 33 jewels and an 80-hour reserve. So the Mido reserve beats the Aquaracer by 42 hours, and only the Carrera matches it.
Build and water resistance
The Ocean Star GMT is 44mm steel with double-sided AR sapphire, a unidirectional bezel and 200m (20 ATM). The Aquaracer Professional 300 is 43mm steel with AR sapphire, a unidirectional bezel and 300m (30 ATM). The Carrera Chronograph is 44mm steel and ceramic with sapphire and 100m (10 ATM). All three are Swiss Made.
For diving depth the Aquaracer is the deepest-rated watch in this comparison by 100m. For a chronograph, only TAG Heuer offers one here.
Price positioning
Both Mido watches in our catalogue sit in the $1,000–$1,500 band. Both TAG Heuer watches sit in the $2,500–$5,000 band. That is a two-band gap for the Aquaracer's extra 100m and TAG Heuer's name, or for the Carrera's in-house chronograph, which is the one thing here Mido does not sell.
