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.

The YEMA x Alain Silberstein Limited Edition is noted for its avant-garde, playful design featuring toy-like hands and a vibrant dial, housed in a 40mm black DLC-coated titanium case. It is powered by the French CMM.20 micro-rotor automatic movement, offering a 70-hour power reserve and rated accuracy of -3/+7 seconds per day. Some reviewers and owners find the sea star and koi motifs on the handset and caseback discordant with the overall aesthetic, and the polished Yema logo and "Marine" label on the dial are considered incongruous with the matte case. The $3,900 price is frequently cited as a significant negative. Overall, opinions on the YEMA x Alain Silberstein Limited Edition are sharply divided, with the price and design elements being the most contentious points.
