The ShengShou 3x3 Magic Clock M is a magnetic version of the classic Clock puzzle, one of the few puzzles recognized within the official WCA regulations that does not have a cube shape. This model corresponds to the standard 9-clock format, three by three on each face, exactly as used in official competition in the Clock category.

The ShengShou Clock puzzle family was released in several formats, with the 3x3 with 9 clocks being the best known and the one that matches the WCA standard. With the magnetic version, the brand adds magnets to the mechanism of the outer wheels, which in practice translates into a firmer, more satisfying feel when turning each wheel, with marked clicks that help count movements more clearly, an important detail on a puzzle where each turn affects several clocks at the same time.

The model weighs around 110 g and comes in a blue housing. The manufacturer classifies it at level 1 of difficulty on its scale, which is consistent with the Clock's mechanics: although the solving logic is not obvious at first, once learned it becomes a relatively quick puzzle to solve, especially compared to large cubes. It is considered a clear improvement over the original ShengShou Clock in terms of fluidity and consistency.

It is a good option for getting into the Clock category within the WCA environment with a current magnetic version, or for anyone who already knows the puzzle and wants to replace an older model with a more reliable one. The Clock puzzle is one of the most particular categories in the competitive scene: it does not require learning a method with many algorithms, but rather understanding the relationship between the wheels and the pins, and once internalized it offers fast and very visual solves. ShengShou's magnetic model has become a benchmark for its value for money.
