The cited Aquaracer Professional 300 Date references suit buyers who want a date display in a 43 mm watch; the cited Professional 300 GMT references add a GMT function, use a 42 mm case, and have a longer manufacturer-stated power reserve. Both are rated by TAG Heuer to 300 m water resistance. These are specification comparisons, not hands-on review findings, and they apply to the references listed below—not every Date or GMT version.
Which Aquaracer should you choose?
- Choose the Date if you want hours, minutes, seconds and a date, and the cited 43 mm case works for you. The two cited U.S. Date references are listed as discontinued, so availability may depend on remaining or secondary-market stock.
- Choose the GMT if tracking a second time zone is useful and you prefer the cited 42 mm case, COSC-certified movement and 80-hour stated power reserve.
Those choices follow published specifications; they do not establish wrist comfort, real-world accuracy, bezel feel or overall superiority. Check the reference number, materials, dial and strap against the exact watch offered for sale.

Date vs. GMT: the practical differences
Case size and configuration
The specific Date examples documented here measure 43 mm; the cited GMT examples measure 42 mm. That one-millimetre difference is a specification, not a reliable prediction of how either watch will feel on a particular wrist. The cited Date options are steel and grade 2 titanium. The cited GMT options use steel cases, with a steel bracelet or blue rubber strap depending on reference.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Calendar and time-zone functions
The cited Date models provide a date display. The GMT adds a GMT function for following another time zone and pairs it with a 24-hour bezel scale. TAG Heuer’s product information lists the same basic time and date functions for both families; the additional time-zone function is the defining complication of these GMT examples.
Movement and power reserve
TAG Heuer specifies an automatic Calibre 5 with a 38-hour power reserve for the cited Date models. For the GMT, it specifies an automatic TH31-03 movement with COSC certification and an 80-hour reserve. These are manufacturer figures, not independent measurements or a guarantee of an individual watch’s accuracy or running time.

Water resistance and bezel

These published ratings and descriptions do not represent independent water-resistance or usability testing.

- Date: TAG Heuer’s U.S. pages mark WBP201A.BA0632 (steel) and WBP208B.BF0631 (grade 2 titanium) as discontinued. That status applies to these cited references, not necessarily every Date configuration or market.
- GMT: The cited references distinguish a green-dial steel-bracelet model (WBP5115.BA0013), a blue-dial steel-bracelet model (WBP5114.BA0013) and a blue-dial model on a blue rubber strap (WBP5114.FT6259). Their product pages document specifications; check local stock and current status before buying.
Confirm the case material, dial, bracelet or strap, condition and seller’s stated reference before purchase. The official product pages are useful for matching specifications, but a product page alone does not establish a retailer’s inventory or the authenticity of a particular listing.

The published specifications make the core trade-off clear: the Date examples offer a date in a 43 mm case, while the GMT examples add second-time-zone functionality in a 42 mm case and have a longer stated reserve. The available evidence does not establish comparative service costs, resale value, real-world accuracy, comfort or performance while diving. Buyers weighing those factors should assess the exact watch and obtain information specific to its condition and market.
