Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Breitling Top Time B01 for its handsome design and sharp finishing, with some calling it one of their favorite watches and sexier than alternatives. Reviewers note the in-house B01 movement, 41mm case that wears smaller than dimensions suggest, and 100m water resistance. Owners appreciate the blue dial that changes with light and unique details like a lightning bolt seconds hand or dials made from automotive paint chips. One owner notes the lug-to-lug length can be a concern for smaller wrists, suggesting an in-person try-on. Accuracy figures vary, with one owner seeing +1/+2 seconds per day and another about -6 seconds per day. The Breitling Top Time B01 offers a 70-hour power reserve and a 5-year warranty. On balance, owners and reviewers rate the Breitling Top Time B01 highly for its attractive design and the value of its in-house B01 movement.
The in-house B01 chronograph movement with its 70-hour power reserve stands out as the defining strength, delivering substantial functionality and reliability across multiple variants. The compact proportions—ranging from 38mm to 41mm cases with lug-to-lug measurements between 44mm and 50mm—ensure comfortable wearability across different wrist sizes. Reviewer assessments diverged sharply on value, with one calling the £5,950 price point excellent value for the specifications, while others provided no pricing commentary.
Owners report the Kobold Phantom SL Avantgarde can be found for better value on the secondary market, though customer service issues and long repair times are significant concerns for some. One owner reported a crown threading issue on their steel Phantom, while another experienced the same problem on a titanium model. Despite these drawbacks, some owners still appreciate the watch's style and build quality. Overall, owners rate the Kobold Phantom SL Avantgarde with mixed feelings due to customer service concerns despite appreciating its style and build quality.
