Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners and reviewers highlight the Audemars Piguet Royal Oak Concept Tourbillon Chronograph Openworked Selfwinding 44mm's visually elaborate skeletonized design, with one owner appreciating the Audemars Piguet script on the dial and the unobstructed flying tourbillon. Reviewers note the skilled decoration of the movement and praise its legibility despite the openworked dial, though one reviewer points out that the black chronograph seconds hand may hinder legibility. The watch is 44mm and offers 100m water resistance. On balance, owners and reviewers appreciate the Audemars Piguet Royal Oak Concept Tourbillon Chronograph Openworked Selfwinding 44mm for its intricate openworked dial and movement finishing.
The Azimuth Crazy Rider is a conversation-starting watch inspired by motorcycles, featuring a literal rotating bike chain on the dial that carries the 24-hour hand. Its design sacrifices minute legibility, with an incomplete minute scale between 35 and 55. The massive 55mm case and 30m water resistance limit it to casual wear. On balance, the Azimuth Crazy Rider appeals to those seeking unusual, avant-garde designs, though its CHF 5,250 price point is considered high.
