What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Tissot PRX UFO Robot Grendizer

The Tissot PRX UFO Robot Grendizer is noted for its unique sunburst blue dial featuring an embossed Grendizer bust, which, along with the hands and indices, offers yellow-green and blue-green luminescence respectively, while the seconds hand is shaped like Grendizer's weapon. This special edition utilizes the Powermatic 80 movement, providing an 80-hour power reserve, and comes in distinctive Spazer spaceship packaging. Reviewers suggest the €120 price premium for these thematic elements and packaging may only appeal to fans of the manga. Overall, reviewers consider the Tissot PRX UFO Robot Grendizer a clever, niche special edition that avoids excessive gimmickry, particularly appealing to manga enthusiasts.

Longines PrimaLuna

Owners widely praise the Longines PrimaLuna for its stylish, understated design and comfortable 26.5mm and 34mm case sizes, with some preferring the quartz for its lower maintenance and others the automatic for its craftsmanship. The automatic movement, an L899.5 or Caliber L899, offers a 72-hour power reserve and exhibits consistent accuracy averaging a loss of 1.3 seconds per day in testing, though it runs 3-4 seconds slower on the wrist. The redesigned collection features a curvier case with contemporary lug integration and is available in steel or bi-metal. On balance, owners and reviewers appreciate the Longines PrimaLuna for its elegant styling and reliable automatic movement, though some find its brand prestige and design less compelling compared to certain luxury alternatives.
