The AndoAndoAndo UFO Watch Prototype 36mm prioritizes experimental shapes and fun over readability, making it very difficult to tell the time on, though future iterations will include lume for better visibility. The 36mm prototype versions may become rare limited editions. Overall, owners rate the AndoAndoAndo UFO Watch Prototype 36mm highly for its unique, experimental design and potential rarity.

Timefactors Everest PRS-25

Owners widely praise the Timefactors Everest PRS-25 for its gorgeous design, flawless finishing, and comfortable 36mm wearability, often calling it the best Rolex Explorer 1016 homage available.
