Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Orient Star Avant-garde Skeleton for its rich dial experience and value, often noting its affordability compared to luxury skeleton watches. The watch features skeletonization on the power reserve and seconds sub-dials, with applied polished markers and lumed hands. Accuracy is generally reported as better than the claimed +25/-15 seconds per day, with some owners seeing under 5 seconds per day. The movement offers a hacking function and a power reserve that sources report as either 50 or 60 hours. Legibility in dim light is considered weak but better than most skeleton watches. One reviewer notes the numeral XII is criticized for not cohering with the rest of the design. The Orient Star Avant-garde Skeleton is priced around $700-$1000 and includes both leather and steel straps. Overall, owners rate the Orient Star Avant-garde Skeleton highly for its detailed skeletonized design and value proposition.
Owners widely report the Orient Bambino Open Heart offers good value, with some appreciating its dressy style and sunburst dial. One owner notes the movement can be noisy and the stock strap feels less premium. The 40.5mm case size is generally considered wearable, though lug width can complicate strap changes. Overall, owners find the Orient Bambino Open Heart to be a good value proposition for its price point, particularly for its aesthetic appeal.
The open-heart dial revealing the balance wheel is a standout feature, typically seen on higher-priced watches. No shared weaknesses were identified.
