The original blue-dial Tissot PRX UFO Robot Grendizer 40mm is reference T137.407.11.041.02. It pairs a luminous Grendizer bust with a Swiss automatic movement, an 80-hour maximum power reserve and a stainless-steel PRX case. It is distinct from the later black PVD 50th Anniversary edition, reference T137.407.33.051.01.
What is the Tissot PRX UFO Robot Grendizer 40mm?
It is a Grendizer-themed version of Tissot’s 40 mm PRX automatic watch. On the original model, a blue dial sets off a luminous image of Grendizer’s bust. Tissot also highlights a Harken-style seconds hand and a decorated rotor visible through the see-through caseback. Swatch Group’s 2024 archive announcement describes the collaboration and the original’s 40 mm steel case and blue dial: Swatch Group archive announcement.

What to check before buying
- Match the reference number to the version you want: T137.407.11.041.02 for the original blue dial or T137.407.33.051.01 for the black PVD anniversary model.
- Verify the seller, regional availability and current price. A past manufacturer listing does not establish present stock or the status of a third-party listing.
- If considering a different strap, confirm fit for the exact reference. Tissot’s original-model page shows an optional black PRX 40 mm leather strap with steel endpiece, but the cited product details do not clearly confirm that strap’s compatibility with this reference.
