The movement is also frequently admired, with one reviewer calling it an "excellent Master Chronometer movement." However, some reviewers and owners note potential issues such as dial printing color, date wheel alignment, and bezel misalignment, while one owner found the hour markers could be brighter for easier reading. The helium release valve is considered a vestigial element by one reviewer, and another owner found the titanium case softer than expected.
