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.
Owners widely praise the Tudor Black Bay Chrono's excellent legibility, solid lume, and comfortable wearability, with one owner noting it feels substantial and masculine. The watch features snowflake hands and hour markers that align with the Black Bay design language, offering a fresh take on a retro chronograph feel.
