Owners widely report the Tudor Black Bay One 31's polished case and bracelet scratch easily, though its wearability under gloves and robust movement are praised. Some desire more micro-adjustment options on the clasp, and a lack of contrast between the silver dial and hands is noted. The 31mm size may be a consideration for daily wear due to its 50-hour power reserve. On balance, owners and reviewers appreciate the Tudor Black Bay One 31 for its comfortable wearability and robust movement, despite concerns about case scratching and clasp adjustability.
