What people say

Owners + reviewers, side by side

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

Echo/Neutra Rivanera Piccolo

The Echo/Neutra Rivanera Piccolo is praised for its charming and impressive design, featuring a lightweight 26mm grade 5 titanium case with a sandblasted finish and polished edges. It is powered by an automatic Sellita SW1000 elaboré grade movement with a 46-hour power reserve and is available with an ultra-black Musou Black dial option. One reviewer suggested removing the date for a cleaner dial, while both sources note the straps lack a quick-release system. Overall, reviewers highlight the Rivanera Piccolo's distinctive design and titanium construction as its primary strengths.

From video reviewers

The thin 6.9mm case is a standout feature. Reviewers noted the Grade 5 titanium case construction. No shared weaknesses were identified.

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.
