Tissot has returned to its successful anime collaboration with a new twist on the PRX, celebrating 50 years of UFO Robot Grendizer. Following the colorful debut edition, the brand now introduces a far more dramatic version: the PRX Grendizer 50th Anniversary Special Edition in Black PVD. With its limited production of just 1,975 pieces worldwide, this release not only pays tribute to the mecha anime classic but also highlights how far Tissot is willing to go in blending watchmaking with pop culture.

A Darker Take on the Anime Collaboration

The first Grendizer PRX was about vibrancy, with a blue dial, colorful Super-LumiNova, and playful accents that leaned into the nostalgia of the series. The new edition takes a different approach entirely. Its case, bracelet, and dial are fully treated in black PVD, creating a stealthy look that feels more aligned with the battle-ready nature of the giant robot itself. Against this dark backdrop, the central design element stands out: Grendizer’s raised fist, appearing to burst through the dial. This detail, combined with engraved textures and selective yellow Super-LumiNova, adds both dynamism and depth to the watch face.

Other touches reinforce the tribute. The eyes of Grendizer glow with lume, and the central seconds hand is shaped like the Double Harken weapon, finished in gold for maximum contrast. Around the bezel, a commemorative engraving marks the 50th anniversary, ensuring that this watch isn’t just another PRX variant but a clear celebration of the anime’s milestone year.

Design, Dimensions & Movement

The watch stays true to the familiar 40 mm PRX case size that has become one of Tissot’s most popular offerings. At just under 11 mm thick, it retains the sleek, integrated-bracelet profile that makes the PRX line so versatile. While black PVD gives the watch a sharper and more aggressive look, it also makes the dial artwork pop in a way that the stainless-steel model could not. The integrated bracelet continues the all-black theme, fitted with a triple-blade folding clasp and Tissot’s quick-release system for easy strap changes.

Tissot equips the Grendizer edition with the Powermatic 80 movement. This automatic calibre offers an impressive 80-hour power reserve. The movement also includes a Nivachron balance spring, designed to provide better resistance against magnetic fields.

The watch is water-resistant to 100 meters, offering practical protection for everyday use. A sapphire crystal covers the dial, while the caseback is fitted with mineral glass to allow a view of the movement.

Collector’s Appeal and Special Packaging

Beyond the watch itself, Tissot has made sure the presentation adds to the collectible value. Each piece comes in a box inspired by Grendizer’s UFO Spazer, a nice thematic nod that fans of the series will immediately recognize. Inside, buyers will also find an exclusive piece of artwork hand-signed by Go Nagai, the creator of the anime. These details elevate the release from being just a branded watch to a true commemorative edition aimed at enthusiasts who value the cultural significance of the collaboration.

With production capped at 1,975 pieces — a number chosen to match the year Grendizer debuted — this edition is designed to be scarce. Each case is individually numbered, giving owners a sense of exclusivity. For anime fans and collectors alike, these touches add a layer of desirability beyond the specs and design.

Pricing and Availability

The PRX Grendizer 50th Anniversary Special Edition in Black PVD is priced at €1,095. While that places it at the higher end of the PRX range, the pricing reflects both the limited production and the licensing tie-in. Considering the movement inside, the quality of the build, and the collectible packaging, the watch presents a compelling case for fans of the series as well as those looking for a PRX variant with genuine character.

Final Thoughts

Crossovers with pop culture, especially anime, are increasingly popular, but not all succeed in balancing fan service with thoughtful watchmaking. The PRX Grendizer in Black PVD manages to strike that balance. Its design is bold without being cartoonish, and its technical package is robust enough to stand on its own even without the theme.

For fans of UFO Robot Grendizer, this watch is both a celebration of the series and a wearable tribute. For collectors who enjoy the PRX line, it represents one of the more creative executions in recent years. Whether you see it as a conversation piece, a nostalgic keepsake, or simply a stylish blacked-out PRX, it’s a release that shows just how versatile this Tissot platform has become.
