ShengShou Magnetic Clock 5x5 — a larger magnetic clock puzzle for Clock fans who want more planning and more dials.

Manufacturer: ShengShou (also commonly seen as “SengSo”). This “5x5” (often referred to as the “Pentagram” variant) features 11 dials per face, 5 turnable gears (side wheels), and 5 pins. The goal is to set every dial on both sides to 12:00.

Who it’s for

• Anyone who already knows the basics of Clock and wants a tougher, bigger variant with more dials.
• Collectors and fans of unusual (non-standard) clock mods.
• Solvers who enjoy slower, logic-heavy sessions where one move affects multiple dials.

Control feel

• Magnets typically help the positions feel steadier and easier to align cleanly.
• With the larger layout and extra dials, it leans more toward planning than pure speed.

Magnets & mechanism

• Magnetic version.
• Center pins can be pressed from the top or pushed up from the bottom; the pin pattern decides which dials move.
• 5 side gears rotate the linked dials.

Size, weight & materials

• Puzzle size (no packaging): about 124 × 124 × 26 mm.
• Puzzle weight (no packaging): about 147–148 g.

Main pros

• Noticeably more challenging than a standard Clock (11 dials per face).
• Magnets improve control when lining things up.
• 5 gears + 5 pins create more combinations and “side effects” per move.

Possible nuances

• This is a specialty variant, usually bought for fun/collection rather than as a replacement for the standard competition Clock.
• The larger footprint can take more space in a bag and on the desk.

How to use

• Pick a pin configuration (pressed/released).
• Turn one of the 5 side gears to move the linked dials.
• Switch pin states and repeat until both faces read 12:00 everywhere.

Packaging

• Package size: about 129 × 129 × 33 mm.
• Shipped weight: about 178 g.
• Boxed item; exact in-box contents can vary by batch/seller.
