Dial
Longines HydroConquest
The Longines HydroConquest showcases a sunray blue dial that adds a captivating sense of depth to its overall aesthetic. The silver-tone secondary color harmoniously complements the stainless steel case and bracelet. The round-shaped hour indices are accompanied by prominent Arabic numerals at the 6, 9, and 12 o’clock positions, drawing attention to these focal points. Thoughtfully positioned at 3 o’clock, the date window maintains visual balance. Notably, Longines has chosen a diamond hour hand design, reminiscent of Tudor’s iconic snowflake hour hand seen in their sports watches. Furthermore, the pencil minute hand introduces intriguing angles, serving as a counterbalance to the curved Arabic numerals. Connecting these elements visually is the lollipop second hand.
Tag Heuer Aquaracer
The dial of the Tag Heuer Aquaracer is very unique and it became a well-loved and recognizable, iconic detail element. This specific watch has a fumée effect dial, with the light blue center darkening gradually towards the edges into a moody dark, almost black hue. Additionally, the horizontally ribbed design element gives a stunningly eye-catching, rugged feel. Overall, the design is kept very clean and masculine, with the hour and minute indices all using straight lines and angles, no curves or round shapes can be found. This to-the-point, serious look is further emphasized with the pencil hour and minute hands.
A date window is positioned at the 6 o’clock position, providing exceptional visual balance and high visibility.
Bezel
Longines HydroConquest
The bezel of the Longines HydroConquest has no surprises. It features a unidirectional count-up ceramic bezel with an engraved 60-minute scale. The Arabic numerals on the bezel are slightly wider, ensuring better synchronization with the numbers on the dial.
Tag Heuer Aquaracer
The bezel of the Tag Heuer Aquaracer is a beautiful visual solution, tying together the straight and angular shapes found within the dial and the round shape that frames the dial itself. This is achieved by employing a slightly serrated bezel design that is broken up into 12 angles. This creates an overall round shape, with still perceptible straight lines. A beautiful, highly harmonious solution.
Case
Longines HydroConquest
In terms of dimensions, the Longines HydroConquest is 43 mm wide, with a 21 mm lug width. A thinner case, measuring 11.9 mm, provides an elegant look as most sports watches have an average 12.5 mm thickness.
Tag Heuer Aquaracer
The Tag Heuer Aquaracer’s case width is 40 mm. The lug-to-lug distance is 47 mm, and the watch has a thickness of 12 mm. It is an excellent size for smaller wrists, but can easily be worn on bigger wrists as well due to the substantial case thickness and visually prominent angles of the bezel. The Aquaracer is water resistant up to 200 meters.
Movement
Longines HydroConquest
The Longines HydroConquest is equipped with the L888 caliber, an automatic movement based on the ETA A31.L11. This 21-jewel movement offers a generous 72-hour power reserve and features a bi-directional winding direction.
Tag Heuer Aquaracer
Powering the Aquracer is the Calibre 5, an automatic movement based on either the ETA caliber 2824-2 or Sellita caliber SW200-1. This movement provides an impressive 38-hour power reserve.
Stainless Steel Bracelet
Longines HydroConquest
Completing the ensemble, the Longines HydroConquest features a stainless steel oyster bracelet. However, Longines takes it a step further by incorporating a combination of brushed and satin finishes. While an all-brushed stainless steel bracelet exudes a sporty vibe, Longines adds a touch of elegance with satin-finished center links.
Tag Heuer Aquaracer
The Tag Heuer Aquaracer comes with a stainless steel oyster bracelet also featuring a combination of brushed and satin finishes. Similarly to the Longines HydroConquest, the bracelet is the perfect blend of sporty and elegant. This blend of styles ensures the highest versatility which we find very important.
Summary
While a lot of people are comparing the Longines HydroConquest to the Tag Heuer Aquaracer, the two watches have distinct visual differences. We recommend trying them on, and analyzing the overall feel of each watch. One should immediately stand out as the more naturally fitting option. For one thing, the Longines is notably bigger with the 43 mm case width compared to the Tag Heuer’s 40 mm. Additionally, the Tag Aquaracer is really focusing on the angles with the overall design, creating a robust and rugged look, while the Longines in contrast employs more rounded, curvy design elements.
Verdict: Longines HydroConquest vs Tag Heuer Aquaracer
Your personal preference is a huge factor, but we’re always transparent here at TWR, so here’s our personal verdict.
Choose the Longines HydroConquest if:
- If you’re looking for a bigger watch, as the Longines 43 mm case width makes it a statement piece.
- If budget is a deciding factor. The HydroConquest is just below $1,500, while the Tag Heuer Aquaracer is slightly above $2,000.
Choose the Tag Heuer Aquaracer if:
- If you’re going for the more rugged, robust look. The Aquaracer’s angular design, and the lack of curves creates an absolute badass of a watch, but depending on your personal preference, that may be an advantage or a drawback.
- If you have a smaller wrist, or thinner arm. The Tag has a 40 mm case width, which is absolutely perfect for smaller wrists.
