Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely report the Undone Tachikoma is a great purchase at its price point. However, some commenters feel the design lacks detailed anime references and find the price too high for an IP collaboration without a recognized watch brand. Overall, owners rate the Undone Tachikoma highly for its value, though opinions are split on its visual connection to the anime.
Owners praise the Longines Conquest Chronograph as a stylish, solid, and easy-to-use automatic chronograph with a bold, sporty design suitable for everyday wear, purchased new for €2,500. Accuracy averages around -3.3 seconds per day, considered normal for a non-certified mechanical watch. The 42mm case, at 14mm to 14.3mm thick, wears larger than expected and can feel top-heavy. One owner suggested the movement could be improved with a flyback function. Overall, owners rate the Longines Conquest Chronograph highly for its bold design and everyday wearability at its price point.
